Cannabis Seed

A cannabis seed is a small, round, dark brown to black seed from the female cannabis plant. The seeds are used to grow new cannabis plants. Cannabis seeds contain high THC and CBD levels, making them ideal for medical and recreational use.


Genotype is the genetic makeup of an organism. In cannabis, genotype refers to the genetic composition of a particular strain of the plant.


Phenotype is the observable characteristics of a plant, like size, shape, color, etc., that are determined by the interaction of its genotype with the environment.


Sativa is one of the two primary varieties of cannabis. This strain is recognized by its long, skinny leaves and tall, thin stalks.



A hydroponic growing technique where roots are suspended in the air and a formulated salt base nutrient solution is finely misted onto the roots for delivery within the plants system. 


A style of aquaculture where the plants get their nutrients from waste of the fish in tanks.  The cycle of cooperation between plants and fish being symbiotic by mimicking a natural ecosystem.


A hydroponic growing technique similar to DWC where plant roots are suspended above a nutrient solution. In this style large amounts of oxygen are generated by incorporation of air stones to the solution. A water pump than pumps water to the top of the plants and it drains through the roots back into the reservoir.

In this technique water is pumped into the flood table until it covers the base of the plant. Water is than drained out of the flood table back into the reservoir.

Flowering Time

The amount of time a cannabis time needs after transitioning a plant from a vegetative state to a flowering state. Flowering time varies by strain but is typically known to be between 8 and 9 weeks long.


This style of growing uses inert growing media such as rockwool, hydroton or coco coir. In this method, all nutrients are provided to the plants with nutrient salts mixed into water. As opposed to natural growing where the soil provides the nutrients.

Indoor Growing

Indoor growing is the process of growing indoors so that environments can be manipulated to the perfect growing conditions year round. The upside is that you have complete control of the environment. Some downsides are the costs associated with electricity and a large building.


Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.

Outdoor Growing

Natural growing using the sun and soil. Downsides of this type of growing is you are limited to one season. Upsides are that the cost is substantially lower to produce a product because it is using the sun for its energy.

Soilless Growing

Also considered hydroponic growing uses an inert growing media and all nutrients are provided to the plants with nutrient salts mixed into a water.

Vegetative State

The time in a plant’s life cycle that is dedicated to maturing and growing.  The plant stays in this state until the photoperiod is changed and can vegetate as long as the light cycle stays over.

Harvesting and Processing

The term used to describe a plant that has fan leaves removed strategically to let in light onto the inner flowers.


Kief, sometimes spelled “keif”, is a popular cannabis concentrate, and the oldest. It comes from the trichomes, or resin glands, of the cannabis plant. These glands are full of cannabinoids and terpenes, which give cannabis its unique flavor and effects. Kief is the after product of trimming a cannabis bud, and generally has a strong THC level compared to flower because of its purity.

Moisture Content

The amount of water left over in a cannabis flower after drying. Moisture content is important in cannabis because if it does not fall below a certain threshold it could cause the flower to mold.

High-frequency Fertigation

With standard fertigation an amount of water is run over the plant once to 3 times a day. With High-frequency fertigation the plants are watered with smaller amounts throughout the day with short burst so that at the end of the day you will have done a complete watering.

Living Soil

According to the National Cannabis Industry Association (NCIA), the definition of living soil is the community of microbes working together breaking down organic matter which, in turn, provides valuable nutrition to the plants. Soil microbes are essential for decomposing organic matter and recycling old plant material.
