Pot is a slang term for cannabis intended for use as a psychoactive drug or a medication. The word came into existence as a shortening of the Spanish potiguaya or potaguaya (a wine or brandy with steeped cannabis buds). Pot also goes by the names of cannabis, ganja, weed, reefer etc.

Powdery Mildew

Powdery mildew is a white powdery growth that forms on the surface of the cannabis leaves. The fungus first appears as small bumps on the upper side of the affected leaves, and if left unchecked it can extend to the petioles, stems and finally the buds, completely destroying the resin and crippling the plant entirely. Also known as Oidium or White Mold, the pest affects both indoor and outdoor cannabis. It is necessary for farmers to take preventative measures from the beginning to keep powdery mildew at bay.

Power Surge

Interruption or change in the flow of electricity.


A pre-roll refers to a pre-formed joint or blunt that is made beforehand and sold in medical dispensaries and retailer stores. The ready-made smokeables come in handy for consumers who like joints but are not good with the rolling process.


A term for cannabis flower, before it’s been processed and turned into oil.

Predatory Insect

Pressed Hash

Pressed hash refers to the compressed resin of the female cannabis plant that is obtained through the application of heat and pressure on kief or dry sift hash to create small, dense blocks containing high concentrations of Tetrahydrocannabinol (or THC) and other cannabinoids. Pressed hash is consumed in much the same way as cannabis buds by smoking in a joint, pipe, bong or consuming it as an edible to offer similar effects. It can result in different colors ranging from dark yellow to brown or even black depending on the amount of plant and foreign material in the final product.
