F

F1

First filial generation, the offspring of two P1 (parent) cannabis plants.


F2

Second filial generation, resulting from a cross between two F1 cannabis plants.


Fan Leaves

Large, fan-like cannabis leaves - fan leaves are usually low in potency.


Fatty

This refers to a rolled cannabis cigarette or joint which is quite large as it contains a large amount of cannabis. Usually, a fatty is shared among a group of people and can last over a period of time. The common use is, 'Want to smoke a fatty?'

Female

Pistillate, ovule, and seed producing cannabis plant.


Feminized

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.

Feral Cannabis

Feral cannabis (often referred to as 'ditch weed') is wild-growing cannabis generally descended from industrial hemp plants previously cultivated for fiber, with low or negligible amounts of psychoactive Tetrahydrocannabinol (or THC).

Fertilize

To apply fertilizer and nutrients to cannabis plants' roots and foliage as well as to impregnate male pollen with female plant ovary.


Fertilizer Burn

Over-fertilization - first, leaf tips brown, then leaves curl.


Fire

Slang for high-quality cannabis - it will usually have a solid amount of red hairs throughout and tons of crystals, but it may also reference a lighter.

Flat

A shallow container used to start cannabis seedlings or clones.


Flower

Blossom, a mass of calyxes on a cannabis plant's stem, top, or bud. 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.

Foliage

The leaves, or more generally, the green part of a cannabis plant.


Foliar Feed

Misting fertilizer solution, which is absorbed by the foliage of a cannabis plant.


Foot-Candle (or FC)

One Foot-Candle (or FC) is equal to the amount of light that falls on one square foot of surface located one foot away from one candle.


Fresh Frozen

Cannabis plant matter that has been cryogenically frozen immediately after harvest, preserving terpenes and the characteristics of the living plant.

Fritted

Full Melt

A concentrate (typically hash) that bubbles and melts at the slightest application of heat. Most consumers like full melt products as it often mean bigger, clearer bubbles, and a higher quality hash.

Fungicide

A product that destroys or inhibits fungus on cannabis plants.


Fungus

A lower plant (lacking chlorophyll) that may attack cannabis plants - mold, rust, mildew, mushrooms, and bacteria are fungi.


Fuse

Fuse Box
