It is a code word used to refer to the socially accepted hour of the day to consume cannabis around 4:20 p.m. (or a.m.) and April 20th (4/20 in the U.S. form) is also celebrated as cannabis’s global holiday. The term originates from San Rafael High School in California (1971) among a group of cannabis-smoking teenagers called the 'Waldos,' who would meet at the campus statue of Louis Pasteur at 4:20 p.m.



Just like 420, 710 is a term used to celebrate dabs and cannabis concentrates on July 10th (7/10 in the U.S. form). The number 710 spells oil when placed backward; a word used to describe potent concentrations of cannabis like hash oil, honey oil, wax, shatter, etc. 710, therefore, is the recognized dab holiday for smoking hash oil due to the number resembling the word ‘oil’ when placed upside-down.



To draw or take in, roots absorb water and nutrients.

Acapulco Gold

A strain of Cannabis Sativa that was popular during the 1960's counterculture movement for its potency and unique color.


A sour substance, an acid or sour soil has a low pH.


A hydroponic system that actively moves the nutrient solution.


Heavy clay soil that drains slowly - adobe is not suitable for container growing.

Adult Use

Any use of cannabis by adults, whether for medicine, pleasure, religious purposes or otherwise. 

Adventitious Roots

Roots that grow from unusual spots, as on the (stem) pericycle or endodermis of an older root - auxins may influence this type of growth.


Also called aerification, it is the process by which air is circulated through, mixed with or dissolved in a liquid or substance. Also, it is essential to supply soil and roots with air or oxygen.


Growing cannabis plants by misting roots suspended in air.


A substrate that is of nearly uniform size and used for the inert hydroponic medium.


The process of breaking off and harvesting trichomes from the cannabis flower through physical contact. Agitation can be made more effective by freezing the product prior to agitation.


Having to do with the economics of agriculture.

Alcohol Extraction

A process in which cannabis is placed in alcohol to extract the cannabinoids from the plant. After the plant is allowed to soak in warm (but not boiling) alcohol for 10 - 20 minutes, it is strained through a coffee filter until it is clear. One of the best alcohol products to use is isopropyl alcohol. The product is then boiled, with or without added pressure, to completely remove any and all alcohol. It is very important to make sure that all alcohol is removed, as isopropyl alcohol can cause blindness if ingested. What remains is hash oil containing around 90% of the cannabinoids from the plant. The longer the extraction, the more oily the product.


Refers to soil, or any substance, with a pH over 7.


A process in which an alkyl group is substituted or added to a compound.


Two genes, each of which occupies the same position on two homogeneous chromosomes.

Alternating Current (AC)

An electrical current that reverses its direction at regularly occurring intervals.

Ampere (or Amp)

The unit used to measure the strength of an electric current.


A plant having staminate (male).


Pollinated by wind-dispersed pollen.


A plant that normally completes its entire life cycle in one year or less - cannabis is an annual plant.

Arc Tube

Container for luminous gases; houses the arc in an High-Intensity Discharge (HID) lamp.


A term used to describe the general smell and/or taste of a certain plant or flower. Because consumers’ individual definition of aromas (such as 'earthy,' 'skunky,' 'citrus,' etc.) can differ somewhat, aroma descriptions are meant as a basic guideline.

Asexual Propagation

Reproducing using non-sexual means such as taking cuttings from a parent plant - will produce exact genetic replicas of the parent plant.


The process of shatter or taffy changing consistency into a budder form. Auto-buddering occurs if a product is kept in too high of heat if it has high wax content or a variety of other environmental factors.


Classification of plant hormones, auxins are responsible for foliage and root elongation.



A type of breeding method that involves crossing a progeny with one of the most desirable original parental genotypes. In cannabis breeding, a hybrid plant is bred with one of its parents to maintain the desired traits of the original parent and enhance those with recessive genes.


Extremely small, single-celled organisms that usually have a cell wall and reproduce by cell division.

Bag Seed

The common term that is given to a seed of unknown origin that was found in a bag of cannabis.


A stabilizing unit that regulates the flow of electricity and starts an High-Intensity Discharge (HID) lamp - a ballast consists of a transformer and a capacitor.

Beneficial Insect

A good insect that eats bad, cannabis-munching insects.


Bhang is frequently used as a synonym for cannabis flowers, though the word itself originally refers to a cannabis-infused beverage produced in the Indian subcontinent. This beverage is occasionally prepared with raw, unheated flowers and is not considered a drug. Sometimes, however, it is heated during preparation and thus made with activated cannabinoids.


To decompose through natural bacterial action - substances made of organic matter can be broken down naturally.


The production of a chemical compound by a plant.


The process of creating hash oil by passing a solvent through the cannabis plant material.


Household laundry bleach is used in a mild water solution to sterilize grow rooms and as soil fungicide.

Blood Meal

High-nitrogen organic fertilizer made from dried blood.


To yield cannabis flowers.

Bloom Booster

Fertilizer high in phosphorus and potassium that increases cannabis flower yield and weight.

Blue Dream

This renowned Sativa-heavy hybrid is one of the most sought-after strains and it is bred from a cross between Blueberry Indica and Haze Sativa, Blue Dream is a great daytime strain - it provides symptom relief without knocking you out for the rest of the day.


A method of smoking cannabis which consists of hollowing out a cigar, filling it with cannabis, and re-rolling it. Blunts tend to be the favorite method of smoking at parties, because one blunt, even with a dozen people smoking it, can burn for a long time. The method was originally nicknamed after the Phillies Blunt brand of cigars. 'Dutchies' referring to blunts rolled from Dutch Master cigars, is another common name. People who avoid tobacco are generally averse to smoking blunts, because most cigar casings are made from tobacco leaf.

Blunt Wrap

Tobacco-based rolling paper designed for people who enjoy rolling their own blunts. The paper mimics the casing of regular cigars, but can come in a wide variety of sizes and flavors. Blunt wraps are taxed as tobacco products in various states, and may require a license to sell.


A bong is usually a glass, ceramic, or plastic apparatus that is used to smoke cannabis flowers, herbal extracts, or tobacco. A bong, similar to a hookah, filters smoke through water so that it may be cooled before it is inhaled. In its simplest form, a bong consists of a bowl and a stem, but as the complexity and artisanship increases and the bong becomes more sophisticated, ash catchers, ice holders, and percolators may be incorporated. These additional 'contraptions' are intended to further purify and cleanse the smoke. 


A very short or dwarfed cannabis plant.


The part of your cannabis instrument of choice (pipe or bong) where you pack (place) the bud. On pipes, there’s often a hole on the side of it that you cover when inhaling cannabis smoke. Alternatively, bowl can be used to refer to the pipe as a whole, or it can be used as a crude unit of measurement.


Small spur-like foliage that grows from the stem at the point from which flowers emerge.

Breaker Box

Electrical circuit box having on/off switches rather than fuses, the main breaker box is also called a 'service panel.'


To sexually propagate cannabis under controlled circumstances.


A bubbler is essentially a cross between a pipe and a bong. It's like a pipe because it has the size and shape of a pipe, and also includes a hole or 'carb' on the side of the bowl. But it also usually has a bulb under the bowl to hold water, allowing water filtration just like in a bong. This is useful if you want something portable like a pipe that still has the potency of a bong. It is named for the sound the water makes when you smoke it.


Bud refers to the actual flower of the cannabis plant. These are the fluffy parts that are harvested and used for recreational or medicinal purposes as they contain the highest concentrations of active cannabinoids.

Bud Blight

A withering condition that attacks cannabis' flowering buds.


A budder is the most potent solvent-extract cannabis product with a Tetrahydrocannabinol (or THC) concentration of up to 99.6%. The cannabis concentrate that is similar to wax but more pliable retains more of the terpenes so it tends to be more flavorful than other types of harsh oils.


A dispensary employee, similar to a pharmacist, who works behind the counter and showcases the stores' different products. They are usually very knowledgeable and will help guide you through your cannabis experience. Remember, they are there to help; if you have any questions from strain types to ingestion methods, feel free to ask.


A substance that reduces the shock and cushions against fluctuations, many fertilizers contain buffer agents.


Outer glass envelope or jacket that protects the arc tube of an High-Intensity Discharge (HID) lamp.

Bulbous Trichome

Ball-shaped, resin-producing plant hair without a stalk.


One of the most popular solvents used in earlier concentrate extraction methods. Butane is marginally cheaper than propane and can be used to produce a wide range of concentrate products.

Butane Hash Oil (or BHO)

A strong concentrate of cannabinoids that is obtained by immersing the cannabis plant in a solvent, normally butane leaving a stick and resinous liquid after the extraction process. It has a high concentration of Tetrahydrocannabinol (or THC) going up to 80% and is also referred to as 'honey oil,' 'earwax' or 'shatter,' depending on the mode of production. Butane hash oil can be smoked, vaporized directly or ingested by mixing it with other edible products.



Tissue made of undifferentiated cells produced by rooting hormones on plant cuttings.


Refers to the sepals found in the cannabis flower that is usually covered in resinous trichomes, containing high concentrations of Tetrahydrocannabinol (or THC) and other cannabinoids. In the case of fertilization, the calyxes become the housing structures for the forming seeds. Growers can really benefit by maintaining seedless calyxes as it increases the potency of the resulting buds.


Layer of cells which divide and differentiates into xylem and phloem and are responsible for growth.


Scientific family to which Cannabis (marijuana) and Humulus (hops) belong.

Cannabichromene (or CBC)

Second most abundant cannabinoid in cannabis, Cannabichromene (or CBC) is considered one of the 'big six' cannabinoids prominent in medical research. It doesn’t get as much attention, but CBC has the same origins as both Tetrahydrocannabinol (or THC) and Cannabidiol (or CBD) do in that they all stem from Cannabigerolic Acid (or CBGA). Cannabis plants produce CBGA, the precursor to three major cannabinoids: Tetrahydrocannabinolic Acid (or THCA), Cannabidiolic Acid (or CBDA), and Cannabichromenic Acid (or CBCA).

Cannabidiol (or CBD)

The second-most common cannabinoid (chemical unique to cannabis) found in cannabis, Cannabidiol (or CBD) are the non-psychoactive ingredient of cannabis that is used to treat a number of diseases, including epilepsy and autism. It was almost bred out of cannabis because people were more concerned with getting high off Tetrahydrocannabinol (or THC), but recently it’s been making a comeback for the aforementioned medical reasons. 

Cannabinoid Hyperemesis Syndrome (or CHS)

Can occur with cannabis use and is characterized by recurrent nausea, vomiting, and crampy abdominal pain. These symptoms have been reported to be improved temporarily by taking a hot shower or bath, or more fully by stopping the use of cannabis. It is important that Cannabinoid Hyperemesis Syndrome be distinguished from other causes of nausea and vomiting, such as cyclic vomiting syndrome

Cannabinoid Profile

Proportional ratio and levels of major cannabinoids found in cannabis being tested. Cannabis testing is the scientific process of measuring different chemicals and compounds in the product. They can measure beneficial constituents like cannabinoids and terpenes, or not-so-desirable contaminants such as pesticides, mold, and residual solvents. Research is now showing that strains exhibit different compound profiles, unique 'fingerprints' built by a specific composition of cannabinoids and terpenes.

Cannabinoid Receptors

Located throughout the body, are part of the endocannabinoid system, which is involved in a variety of physiological processes including appetite, pain-sensation, mood, and memory. Cannabinoid receptors are of a class of cell membrane receptors in the G protein-coupled receptor superfamily. There are currently two known subtypes of Cannabinoid Receptors, termed CB1 Receptor and CB2 Receptor. The CB1 Receptor is expressed mainly in the brain (Central Nervous System), but also in the lungs, liver, and kidneys. The CB2 Receptor is expressed mainly in the immune system and in hematopoietic cells.


A hydrocarbon unique to cannabis, it produces a variety of compounds known as cannabinoids, many of which have not been detected in any other plant. Most of them are present at very low levels, especially in commercial cannabis products, making it difficult for scientists to accurately detect them. The important point is that there are many. Cannabinoids are a large class of compounds that act on the brains cannabinoid receptors in cells that repress neurotransmitter release. Tetrahydrocannabinol (or THC) is the most well-known cannabinoid due to its euphoric and psychoactive effects on your body (ex. the 'high'). THC can alter behavior, consciousness, mood, and perception. Most health benefits of cannabis are associated with the Cannabidiol (or CBD) cannabinoid. Cannabis products are often enhanced with CBD to provide more potent effects. Choose a strain with high levels of CBD if you're looking to use cannabis as an alternative form of medication. 

Cannabinol (or CBN)

Cannabinol (or CBN) is a non-psychoactive cannabinoid found only in trace amounts in Cannabis and is mostly found in aged Cannabis. Pharmacologically relevant quantities are formed as a metabolite of Tetrahydrocannabinol (or THC). CBN acts as a partial agonist at the CB1 Receptors, but has a higher affinity to CB2 Receptors; however, it has lower affinities relative to THC. Degraded or oxidized cannabis products, such as low-quality baled cannabis and traditionally produced hashish, are high in CBN, but modern production processes minimize the formation of CBN.


Cannabis is a plant genus that produces three species of flowering plants: Cannabis Sativa, Cannabis Indica, and Cannabis Ruderalis. Cannabis Sativa and Cannabis Indica are used to produce both recreational and medical cannabis. Cannabis Ruderalis is rarely farmed due to its natural lower Tetrahydrocannabinol (or THC) content and small stature, but there is some cross-breeding thanks to Ruderalis‘ unique ability to auto-flower rather than mature based on light, so there is potential for this variety to grow in popularity. Cannabis is native to Asia, but grows almost anywhere and has long been cultivated both for the production of hemp and to be used as a drug.

Cannabis Concentrate

A cannabis concentrate [also called concentrates, extract, shatter, wax, butane hash oil or Butane Honey Oil (or BHO), live resin, budder, and taffy] is a highly potent Tetrahydrocannabinol (or THC) concentrated mass that is most similar in appearance to either honey or butter, which is why it is referred to or known as 'honey oil' or 'budder'. Cannabis concentrates contain extraordinarily high cannabinoid levels that could once range from 40 - 80%, up to four times stronger in cannabinoid content than the high grade or top-shelf cannabis, which normally measures around 20% THC levels. 

Cannabis Consumption

Cannabis consumption refers to the variety of ways cannabis is consumed, among which inhalation (smoking and vaporizing) and ingestion are most common. Each method leads to subtly different psychoactive effects due to the Tetrahydrocannabinol (or THC) and other chemicals being activated, and then consumed through different administration routes. It is generally considered that smoking, which includes combustion toxins, comes on quickly but lasts for a short period of time while eating delays the onset of effect but the duration of effect is typically longer. Researchers reported that vaporizer users experience the same biological effect, but without the toxins associated with smoking.

Cannabis Cup

The High Times Cannabis Cup is the world’s foremost cannabis festival. Founded in 1988 by Steven Hager, the  Cannabis Cup is the world's leading cannabis event and most trusted cannabis strain competition in the industry. The event allows judges from around the world to sample and vote for their favorite cannabis varieties. These judges-at-large decide the Cannabis Cup (overall winner in the cannabis variety competition), best new product, best booth, best glass, etc. A team of VIP judges decides which seed company has grown the best Indica, Sativa and hybrid strain and which company has produced the best. The High Times Cannabis Cup also includes live music, educational seminars and an expo for cannabis-related products from cannabis-oriented businesses.

Cannabis Essential Oil

Known as 'Hemp Essential Oil,' is an essential oil obtained by steam distillation from the flowers and upper leaves of the hemp plant (Cannabis Sativa) Hemp essential oil is distinct from hemp seed oil, hemp oil, and hash oil: the former is a vegetable oil that is pressed from the seeds of low-cannabinoid varieties of hemp, the latter is a cannabinoid-rich extract of dried female hemp flowers (cannabis) or resin (hashish).

Cannabis Flowers

The flowering part of the cannabis plant that can either be male or female. Female flowers usually produce Tetrahydrocannabinol (or THC) and other cannabinoids in higher amounts than the other parts of the plant. The female flowers are fertilized by the male plants to produce cannabis seeds. If left unfertilized, the female flowers continue to produce the resin that contains active cannabinoids until their point of harvest.

Cannabis Indica

Formally known as Cannabis Sativa, is an annual plant in the Cannabaceae family. It is a putative species of the genus Cannabis. Whether it and Cannabis Sativa are truly separate species is a matter of debate. Many uses come from Cannabis Indica, such as extraction, cultivation, cloth from the fibers, medical uses, and a drug plant. Cannabis Indica produces large amounts of Tetrahydrocannabinol (or THC). The large amounts of THC make it most commonly used as a drug, whether it be for recreational or medical purposes.

Cannabis Oil

Refers to a sticky, dark-red potent concentrate commonly consumed by dabbing or vaporizing. It is extracted by the use of solvents e.g. butane, ethanol or naphtha to separate the cannabinoids and essential oils from the plant material. Cannabis oil has high concentrations of Tetrahydrocannabinol (or THC) and Cannabidiol (or CBD) making it ideal for a broad range of medical conditions like cancer, chronic pain, anxiety, depression, convulsions etc. It releases pleasure hormones, relaxes the mind and induces a sense of calm and relaxation. Cannabis oil is usually consumed in vape pens, bongs, and bubblers.

Cannabis Prohibition

Laws in some jurisdictions banning the cultivation or sales of cannabis in an attempt to prevent its use - these bans are criticized because they create a black market and law enforcement is disproportionately enforced around the world.

Cannabis Ruderalis

A low-Tetrahydrocannabinol (or THC) species of Cannabis which is native to Central and Eastern Europe and Russia. Many scholars accept Cannabis Ruderalis as its own species due to its unique traits and phenotypes which distinguish it from Cannabis Indica and Cannabis Sativa, however, it is widely debated as to whether or not Ruderalis is a sub-species of Cannabis Sativa.

Cannabis Sativa

An annual herbaceous flowering plant indigenous to eastern Asia but now of cosmopolitan distribution due to widespread cultivation. It has been cultivated throughout recorded history, used as a source of industrial fiber, seed oil, food, recreation, religious and spiritual moods, and medicine. Each part of the plant is harvested differently, depending on the purpose of its use. The species was first classified by Carl Linnaeus in 1753.

Cannabis Strains

Are either pure or hybrid varieties of the plant genus Cannabis, which encompasses the species Cannabis Sativa, Cannabis Indica, and Cannabis Ruderalis.

Cannabis Tea

Also known as herbal tea, weed tea, pot tea, ganja tea, or green tea is a cannabis-infused drink made with cannabis-infused in hot or cold water. Properly produced decarboxylated cannabis teas are very effective when ingested.

Capitate Stalked Trichome

Resin-producing plant hair without a stalk, high in Tetrahydrocannabinol (or THC) content.

Carb Cap

A carb cap is a dabbing tool used to vaporize concentrates at low temperatures to optimize the flavor and give a smoother experience. The concentrate is placed onto the nail (hot surface) and the device creates a chamber with restricted airflow for the concentrates to vaporize within. It is made of glass, ceramic, quartz or titanium and features a hollowed-rounded head (cap) and a pointed handle that doubles as a dabbing tool to help with concentrate application.


A neutral compound of carbon, hydrogen, and oxygen, mostly formed by green plants - sugar, starch, and cellulose are carbohydrates.

Carbon Dioxide (or CO2)

A colorless, odorless, tasteless gas in the air and necessary for plant life.

Carbon Dioxide (or CO2) Enrichment

Adding carbon dioxide (or CO2) gas to augment grow room or greenhouse atmosphere to speed the cannabis plants' growth.

Carbon Dioxide (or CO2) Extraction

Also known as supercritical carbon dioxide (or CO2) extraction, CO2 extraction is a technique that freezes and compresses CO2 to its supercritical state then passes the cold CO2 liquefied gas through cannabis, pulling all of the essential cannabinoids, terpene oils and waxes out of the plant material into collection receptacles. The method leaves no residue and produces an amber-colored oil which can be vaporized in a number of ways.

Carbon Dioxide (or CO2) for Cultivation

It is the addition of carbon dioxide (or CO2) to cannabis gardens to quicken the plant development and pack weight onto their buds, increasing the crop’s yield. Cannabis growers operating a closed system use CO2 generators to increase concentrations of carbon dioxide to around 800 - 1,500 Parts-Per-Million (PPM). The use of CO2 for cultivation, however, is more effective if the plants are fed with more hydroponic nutrients, light, and water.


This refers to the state of depleted cannabis whose contents have been thoroughly used up leaving behind an ash residue. Cannabis smokers use the term to describe a bowl that has been smoked out until all resin is gone and there is nothing but ash. Cannabis that has reached its cashpoint should be emptied and repacked.


A substance that destroys, kills or eats away by chemical activity.


The base structural unit of plants - a cell contains a nucleus, membrane, and chloroplasts.


A complex carbohydrate that stiffens a plant - outdoor stems contain more stiff cellulose than plants grown indoors.


A scale for measuring temperature where 100 degrees is the boiling point of water and 0 degrees is the freezing point of water.


A chalice, also known as a wisdom chalice or chillum chalice, is a type of cannabis smoking pipe used most often by members of the Jamaican Rastafari movement. It is a sort of water pipe with a hose, or drawtube, for inhaling; the water cools and filters the smoke and the hose provides additional airspace for cooling. A screen embedded in the crater protects against drawing in burning particles to clog the interior.


Charas (Hindi/Urdu) is the name given to a hashish form of cannabis which is handmade in many South Asian countries and Jamaica. It is made from the resin of the cannabis plant (Cannabis Sativa or Cannabis Indica). The plant grows wild throughout Northern India along the stretch of the Himalayas (its putative origin) and is an important cash crop for the local people. The difference between charas and hashish is that hashish is made from a dead cannabis plant and charas is made from a live one.

Charlotte's Web

Charlotte's Web is a high-Cannabidiol (or CBD), low-Tetrahydrocannabinol (or THC) Cannabis strain, it does not induce the psychoactive 'high' typically associated with recreational cannabis strains that are high in THC.


Cheeba is a slang word for cannabis. Cheeba Chews are medical cannabis-infused edibles that are usually gummy and compressed into small bricks.


Metal chelate compounds are common components of fertilizers to provide micronutrients. These micronutrients (manganese, iron, zinc, copper) are required for the health of the plants. Most fertilizers contain phosphate salts that, in the absence of chelating agents, typically convert these metal ions into insoluble solids that are of no nutritional value to the plants. Chelation is a type of bonding of ions and molecules to metal ions, usually, these ligands are organic compounds and are called chelants, chelators, chelating agents, or sequestering agents.


A bowl that will stay burning without the need for a lighter or match. Cherried bowls are much simpler to smoke because you just have to keep hitting it to keep it cherried. It's important to note, however, that because your cannabis will be continuously burning whether or not you're smoking it, you have to be careful that a cherried bowl doesn't smoke itself.


A term for a small device that can be carried around discreetly and holds a very small amount of cannabis. 


A plant or organism with tissues from at least two genetically distinct parents.


Green photosynthetic matter of plants - chlorophyll is found in the chloroplasts of a cell and is necessary to photosynthesis.


The condition of a sick plant with yellowing leaving due to inadequate formation of chlorophyll, chlorosis is caused by a nutrient deficiency.


Microscopically small, dark-staining bodies visible in the nucleus of a cell at the time of nuclear cell division and the number in any species is usually constant - a cannabis plant has 10 pairs of chromosomes.


A circular route traveled by electricity from a power source, through an outlet, and back to the ground.

Clam Baking

Smoking in an enclosed space or car so that it fills up with smoke.

Clay Soil

Soil made of very fine organic and mineral particles, clay soil drains slowly and is not suitable for container gardening.


The average condition of the weather in a grow room or outdoors.


A clone is a cannabis plant clipping that can be planted and grown, creating a genetic copy of the mother. Scientifically, cloning is the act of asexually propagating the cannabis plant to create a genetic copy. Cloning is very popular in the cannabis industry and many strains are simply 'clones' that are passed from one grower to another.

Closed-Loop Extraction

Most commonly referring to butane or propane extraction, closed-loop extraction is a chemical extraction process that recycles hydrocarbon solvent or carbon dioxide (or CO2) in a closed system, opposed to releasing the gas into the air. The closed-loop method is far safer than open blasting.


The cola is the large flower cluster at the top of a cannabis plant's main stem (larger side branches can also contain cola nugs). The cola is heavily-coated in kief, which makes it both the strongest and tastiest part of a cannabis plant to smoke. Mexican and North American slang word for cannabis flow top - 'cola' in Spanish actually means tail.


A poisonous alkaloid from the autumn crocus, used in plant breeding to induce polypoid mutations.


For cannabis plants, air temperatures below 50 F (10 C).

Cold Frame

An unheated outdoor structure usually clad in glass or clear plastic used to protect and acclimatize cannabis seedlings and plants.

Color Spectrum

The band of colors (measured in Nm) emitted by a light source.

Color Tracer

A coloring agent that is added to many commercial fertilizers so the horticulturist knows there is fertilizer in the solution.


The process of burning a material - combustion occurs when smoking flower.


Soil condition that results from the tightly packed soil which limits aeration and root penetration.

Companion Planting

Planting garlic, marigolds, etc., along with cannabis plants to discourage pests.


A mixture of decayed organic matter, high in nutrients - compost must be well-rotted before use.


It is a highly potent Tetrahydrocannabinol (or THC) concentrated mass obtained by the use of a solvent to dissolve essential oils and resinous cannabinoids from the plant material. Cannabis concentrates are loved for delivering high THC levels and allowing individuals to take them in ways other than smoking joints including dabbing and use of vaporizers. Concentrates are referenced under different names like Butane Hash Oil (or BHO), wax, oil, shatter, crumble etc.

Concentrate Slurry

Pre-purged concentrate that has high Parts-Per-Million (or PPM) of residual solvent - slurry can be either solid and airy, or liquefied and runny.


A cone is a type of joint that is more conical than a typical joint or cigarette. The cone starts straight and thin but widens as the cone gets longer. A crutch or filter is often included and stops the cannabis from falling out of the bottom of the cone and it also stops resin from clogging the end of the joint.


The transfer of heat within a melted concentrate liquid that, in combination with inhaled airflow, circulates current and evenly vaporizes the concentrate - convection occurs when using a carp cap.


The transformer in the ballast is often referred to as a core.

Cotton Mouth

It is a common effect of cannabis that causes one to have a dry and sticky feeling in the mouth. Consuming cannabis regardless of the method dries out the mucous membranes and may cause one’s salivary glands to produce less spit or saliva. The condition also known as dry mouth or hypo-salivation can be managed by drinking plenty of water.


Seed leaves, first leaves that appear on a cannabis plant.

Couch Lock

An instant high-effect that leads to a sedative kind of experience once you have consumed cannabis, higher terpene levels in the strain is responsible for the couch lock sensation.


Usually used in reference to Indica-heavy strains that make you groggy or sleepy - if you smoke some couchy cannabis while you’re on a couch, you’re probably not getting up anytime soon.


Cannabis high in Cannabidiol (or CBD) having psychoactive qualities that sneak up on the smoker - highs usually last longer.

Critical Day Length

Maximum day length which will bring about flowering in cannabis plants.


The act of breeding different species or strains of cannabis to produce unique, better cannabis varieties. Most of the strains available in the market today are crossbreeds of different strains. The goal is to obtain desirable traits of both parents within one’s gene pool so hybrids not only have to be a Sativa/Indica-cross but can be two different strains of the same type.


Fertilizing a cannabis plant with pollen from an unrelated individual plant of the same species.


Usually made from a small piece of thick paper (such as the inner lining of a cigarette carton or the outer flap of a pack of rolling papers), a crutch is a short cylinder rolled into a joint or spliff at the side that touches your lips. The crutch serves a dual purpose - first, it prevents the end of the joint from getting wet and collapsing in on itself, making smoking it rather unpleasant. Second, it makes rolling the joint easier - the shape of the crutch determines, at least to a certain extent, the shape of the joint.


Crystals or trichomes are the part of the cannabis plant that holds the most cannabinoids and is specifically used to make concentrates like kief or hash. Typically when looking at buds, the more crystals you see, the more potent the product.

Cubic Feet-per-Minute (CFM)

Measures air velocity - ventilation or extraction fans are measured in the Cubic Feet-per-Minute (CFM) of air they can move.

Cubic Foot (or Meter)

Volume measurement in feet (or meter): width x length x height = cubic feet (or meter).


A contraction of 'cultivated variety,' a variety of plant that has been intentionally created or selected - not naturally occurring.


Curing is a very important process during the growth of a cannabis plant, which allows for a much higher quality end product. When you move your plant from the drying process to curing at just the right time, one will have more control over the level of moisture of the bud, allowing for the grower to greatly increase it’s flavor, potency and other desired characteristics. If not cured properly, one will experience a harsher inhale or even bad smelling bud.


A thin layer of plant wax (cutin) on the surface of the aboveground parts of cannabis plants.


Dab (or Dabbing)

The process of smoking cannabis concentrates like butane harsh oil, budder, wax or shatter by placing a ‘dab’ of cannabis concentrate onto a heated surface is known as a nail. The super-high concentrates are made by extracting Tetrahydrocannabinol (or THC) which is a strong psychoactive chemical compound and through a process that uses hydrocarbons as the solvent. Dabbing provides a different and more powerful high than smoking buds or flowers thus one should know their limits so as not to overdo it.


It is a long, pointy tool used to place the cannabis concentrates to a heated surface or nail while you suck the bong to get the smoke - it’s made of glass or metal and helps a user to dab safely without risking getting hurt.


Fungus disease that attacks young cannabis seedlings and clones causing the stem to rot at the base - over-watering is the main cause of damping-off.


A term used by people who regularly get high to refer to something of superior quality. More specifically, it can be used to refer to very strong smelling and thus high-quality cannabis. Dank would be synonymous with words like remarkable and awesome.

Decarboxylate (or Decarbing)

Decarboxylation of cannabis involves exposure of the cannabinoids to extremely hot temperatures (like smoking), thus removing the acidic component of the compound and converting it into a more desired cannabinoid. Acidic compounds such as Tetrahydrocannabinolic Acid (or THCA) and Cannabidiolic Acid (or CBDA) are transformed into Tetrahydrocannabinol (or THC) and Cannabidiol (or CBD) respectively. Once cannabis decarboxylated, it can be used in edibles or tinctures.


To rot or decay, etc., through organic chemical change.


To remove moisture from the air.

Dugouts are popular because of its semi-discreetness and level of easiness to use.



An invention in concentrate and dabbing communities, specifically, E-Nails are digitally controlled heating devices that allow the user to keep a consistent heat setting so as to always get the best tasting and potent hit. Compared to the typical hand torch, which often delivers varying results, this tool takes dabbing to the next level.


A product is made by whipping oils extracted from the hash, you can mix the oil using a whisk that you would typically use for whipping heavy cream into whipped cream. However, unlike the baking process, the hash oil must be heated while being whipped with the whisk. The oil substance will become lighter and fluffier in texture and is often considered more delightful to smoke.


Edibles are cannabis-infused products that are consumed orally, versus smoking flower or concentrate. Some of the more common forms of edibles include baked goods (like brownies and cookies) and candy (like chocolate, gummies and lollipops), but can also be found in coffee, beef jerky, soda and more. Eating an edible is different than smoking bud because it’s being digested versus inhaled, which often results in a more intense and elongated high. When consuming an edible, it’s always safe to go slow and feel the intended effects first before consuming more.

Feminized plants come from seeds that have been selectively bred to produce only female plants since they produce flowers (which is where most of the cannabinoids are found) and are the only ones that are used to create cannabis products. Feminized seeds are intended to make things easier for growers by eliminating the need to determine the sex of growing plants and remove males early on to prevent fertilization. Generally, feminized seeds produce the same quality of plants as naturally produced seeds.

The flowers of a cannabis plant refer to the hairy, often sticky bud or parts of the plant that are harvested and used to consume in a variety of cannabis products. Technically speaking, they’re the reproductive organs of the plant and when fertilized by a male plant, seeds will be produced. The word 'flower' is slowly becoming a replacement word among professionals in the cannabis industry and this is because the highest-quality cannabis consists of only undeveloped flowers, also known as the plant's buds.

Flower Child

This term originated as a synonym for hippie, especially among the idealistic young people who gathered in San Francisco and the surrounding area during the Summer of Love. It was the custom of 'flower children' to wear and distribute flowers or floral-themed decorations to symbolize the ideals of universal belonging, peace, and love. The mass media picked up on the term and used it to refer in a broad sense to any hippie. Flower children were also associated with the flower power political movement, which originated in ideas written by Allen Ginsberg.

Flowering Time

Flowering time references the period in which a cannabis plant produces flowers (bud), typically after the vegetative stage when it’s been actively growing. A plant enters the flowering time when its exposure to light hits 12 or fewer hours a day, typically around the fall in nature. Having said this, growers have the ability to manipulate an artificial growing ecosystem to ensure that their cannabis plants flower at a specific time. After cannabis plants have entered the flowering phase and are subjected to a schedule of 12 hours of darkness followed by 12 hours of light, they will begin to produce flowers at an increased rate.

Hash or hashish is the resin collected from the flowers of the cannabis plant and a colloquial term. The active ingredient in the hash is Tetrahydrocannabinol (or THC) and hash can be smoked in joints or out of bongs or pipes. The effects of a high caused by smoking hash include sleepiness, pain relief, a feeling of relaxation, and increased appreciation of music and food. Most of the THC from hash is absorbed and catalyzed within the first few seconds of entry into the body, so holding smoke into the lungs for a longer amount of time will not hasten the achieved high.

Hash Oil

Hash oil or cannabis oil is obtained by the extraction of cannabis or hashish. It is a concentrated form of the plant containing many of its resins and terpenes - in particular, Tetrahydrocannabinol (or THC), Cannabidiol (or CBD), and other cannabinoids.

When it comes to growing cannabis, a plant’s phenotype is important because it determines a strain’s taste, effectiveness, look and more. Simply put, phenotype is a word used to successfully identify a plant’s inherent traits. Every strain has two parent plants, including a male and female. Like in most breeding of organisms, when a male plant fertilizes a female plant, the seeds that are produced will include genetic phenotypes from both plants. Because people like varying traits from different strains, growers can make a specific strain based on those preferred characteristics.

Ruderalis is one of the three species of cannabis besides Indica and Sativa. Originally, Ruderalis was considered as a wild breed of cannabis that can survive human activities and even adapt to extremely harsh conditions. The plant has small leaves and a short stature that only grows to about 2 feet (or .6 meter) tall hence the name dwarf cannabis. Ruderalis most notable characteristic is its ability to begin flowering based on changes in the plant instead of its environment (auto-flowering). The plant has low Tetrahydrocannabinol (or THC) concentrations making it less favorable for recreational or medical use. It’s native origin is traced back in Russia.

Sativa plants are tall with long, narrow leaves and loosely attached branches, Sativa is native to the temperate warm climates of Mexico, Central America, and Southeast Asia. It is usually grown outdoors due to its tall stature, going to heights of up to 18 feet (or 5.5 meters). Since its vegetation period is much longer, these plants typically produce a much higher yield than Indica strains. The plant has lower Tetrahydrocannabinol (or THC) to Cannabidiol (or CBD) levels, explaining its stimulating properties characterized by uplifting, euphoric and cerebral highs.

The plants get into the flowering phase after only two weeks of vegetative growth, and are harvested much earlier than they would if they grew to full size. The method allows the growers to maximize their space by fitting more plants without sacrificing on the yield. The method involves switching the plants lighting to 12 hours on and12 hours off to initiate flowering. If started at the same time, the plants should create a green canopy that traps most of the light at the top level.

Smoking a spliff results in a mild high as one is consuming less bud that has been combined with nicotine. The term is also used to refer to a nicely rolled cannabis joint.


A sploof is usually a hand-made gadget to try to mask the smell of cannabis smoke. Usually constructed out of plastic water bottles with holes stabbed through the bottom, a sploof is usually stuffed with dryer sheets.

Small mouth-like or nose-like openings on leaf underside, responsible for transpiration and many other life functions - the millions of stomata must be kept very clean to function properly.


If you haven't figured it out by now, being stoned is a euphoric sensation you experience following the consumption of cannabis. It is a result of the cannabis plant's many psychoactive components, though mainly Tetrahydrocannabinol (or THC). It is certainly possible to get uncomfortably stoned, but nobody has ever died from it.

Each strain is grown to increase certain traits of the plant, with names being chosen by the actual grower to mirror the strain’s color, taste, smell, origin or physical effect on the user. There are hundreds of strains available, with more being produced every day thanks to the many options to crossbreed. It’s important to note that the cannabis industry is trying to maintain some type of consistency between each strain, but unfortunately, many of them are misclassified or marketed improperly causing confusion for the dispensary owner or buyer.

A large and diverse class of organic compounds, produced by a variety of plants, particularly conifers, and by some insects. They often have a strong odor and may protect the plants that produce them by deterring herbivores and by attracting predators and parasites of herbivores. Although sometimes used interchangeably with 'terpenes,' terpenoids (or isoprenoids) are modified terpenes as they contain additional functional groups, usually oxygen-containing and terpenes are hydrocarbons.

Terpene Distillation

The process of isolating and extracting terpenes directly from cannabis flowers through molecular distillation.

Tetrahydrocannabinol (or THC)

Transplanting your cannabis plants can be one of the trickiest parts of growing your cannabis plants. Once your plants have established a stable root system, they are ready for a period of major foliage growth. If you don't transplant your plants in time they might get rootbound. Rootbound means that the roots have grown all the way around the edges and your plant will not grow any more until you transplant it to a larger container.


A slang term for cannabis that references the shape of certain buds, when trimmed, nugs of cannabis often look like little trees.


This is one of many treasures that’s resulted from the great melting cannabis in culture - 'treefer' is a slang term for cannabis that combines the terms 'tree' and 'reefer.'

It can be positioned vertically or horizontally to maximize available grow space and light penetration in any cannabis garden. This allows the grower to dramatically increase yields.


Trichomes are crystalized glands that produce resin on a cannabis plant. Often referred to as 'sticky little hairs,' these glands are not actually hairs or crystals (although they’re still very beautiful close-up). Instead, they’re specific parts of the plant that carry the majority of cannabinoids and cover the cannabis plants' major surfaces. Under a microscope, trichomes look like mini mushrooms, with each section providing certain value to the plant. The head is most valuable and is frequently turned into a quality sieve or water hash.


Trim is the leftover bits of cannabis leaf and smaller buds that you collect huge piles of when trimming a freshly-harvested plant. Trim can often be used to make extracts like hash because you usually end up with so much of it and it still contains many valuable cannabinoids - the natural concentration of cannabinoids in such ancillary parts of the cannabis plant, however, is just not as concentrated.

Trim Run

Trim run describes a concentrate made from the trimmings of a cannabis plant. Growers often make huge batches of trim run because they often are left with huge quantities of leaves, stems, and tiny nugs after harvesting a crop. Trim run, however, is still sufficiently potent for most people, and some producers have found that the difference between trim run and nug run (concentrate made from cannabis) is nearly negligible.


Having three sets of chromosomes within each cell may contribute to increased vigor.

Vape Pen

A smaller version of a regular vaporizer, it’s portable and typically uses pre-filled cartridges available in varying sizes and types of cannabis, including Sativas, Indicas, and Hybrids. In some variations, there is an option to fill the chamber with your own flower or concentrate. Vape pens and their sister product, e-cigarettes, have gained popularity within the world of cannabis because of its discreetness and lack of smell when used.


A vaporizer is a device that functions by heating the flowers or oils to a specific temperature causing them to release an odorless vapor that is then inhaled directly. Studies have shown that vaporizers are a healthier alternative to smoking as the devices are designed to produce an inhalable vapor that preserves the active ingredients of cannabis without destroying the material which could lead to intake of harmful substances.


A distinct cannabis strain or phenotype.


Referring to a cannabis plant's circulatory system which carries sap throughout the body of the plant.


An organism (as an insect) that transmits disease, a pathogen, or an organism that transmits genes, a pollinator.

Vegetative Stage

The vegetative state refers to the growing phase of the cannabis plants characterized by the establishment of a solid root system and full leaf development in preparation for the flowering stage. The vegetative cycle of a cannabis plant takes about 4 - 6 weeks depending on plant strain and the surrounding environment. Growing plants should have access to at least 18 hours of light in a 24-hour cycle to maximize photosynthesis to produce as much leafy foliage as possible. The vegetative stage is also an ideal time to get clones if you are interested in a particular strain.

Vending Machine

A cannabis vending machine is a vending machine for selling or dispensing cannabis. They are currently in use and some may be located in secure rooms in dispensaries. Some may be operated by employees after a fingerprint scan is obtained from the patient.

Washing Machine

A tool for making bubble hash that mechanically mixes the cannabis and ice mixture.

Water Hash

Also known as ice water hash or bubble hash, is a specific technique to separate Tetrahydrocannabinol (or THC) trichomes to isolate the resin in cannabis. Using micro screens, ice, and water, one can effectively strain out resin glands that are inherently more dense than water. Large quantities of pure resin can be removed from the plant material, water ice water separation is a cleaner method that doesn’t involve other solvents and allows for a more refined hashish.

Water Table

It refers to the underground surface within which the soil is saturated with water and optimum soil-air environment conditions should be maintained within the root zone in order to achieve good crop yields.


It is a general term used to refer to extracts that are solid, opaque and with a soft texture. In its preparation, cannabis buds are packed tightly into a tube and then blasted with butane (a highly flammable liquid) that separates the trichomes from the material resulting in a concentrated substance. It is available in different consistencies and variations like honeycomb, crumble, earwax, sugar etc. with the difference arising from the extraction and purging process used in each variety’s production. 

Waxes and Lipid Fats

Naturally occurring substances found within the cannabis plant; waxes and lipid fats are often removed during shatter concentrate production.


Another slang term for cannabis and it’s frequently used, specifically in reference to flower.
