A crystalline compound that results from improper pH or toxic build-up of fertilizer - salt will burn plants, preventing them from absorbing nutrients.


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.


Schwag is a word to describe low-quality cannabis that’s typically brown in color and very dry. Most often, a lot of seeds and stems will need to be removed before smoking the actual cannabis.

Sea-of-Green (or SOG)

Usually abbreviated as SOG, Sea-of-Green is a method of growing cannabis that forces the plants to mature early to get the best yields possible. 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.

Secondary Nutrients

Secondary nutrients are nutrients that slightly limit crop growth and are moderately required by plants. These nutrients are calcium (Ca), magnesium (Mg), and sulfur (S). Secondary nutrients are as significant as primary nutrients in plants, but they are needed in smaller quantities. They are necessary for the augmentation levels of roots and cells.
