A shallow container used to start cannabis seedlings or clones.


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.


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

Fresh Frozen
