Definition - What does Bud mean?
In cannabis culture, the term 'bud' is commonly used to refer to the dried, cured, and consumable portions of the marijuana plant. These are what would be found in storage containers and on display at dispensaries. Hence the term, 'budtender'.
The aroma and appearance of the buds are usually an indicator of their quality. Buds can either be completely dried (brittle) or more sticky.
Before processing, and in more scientific terms, the bud is the actual flower of the marijuana plant. The female bud contains the highest concentrations of cannabinoids in the plant, especially tetrahydrocannabinol (THC).
Hydrolife explains Bud
When a cannabis plant is about six weeks old, it starts to leave the vegetative stage and develop buds. Initially, the plant develops two white hairs. This is the location where the bud will form. Once the formation begins, buds usually take about two to five weeks to fully form. The hairs develop on the main stems where the branches meet. The female bud produces ample resin that is rich in terpenes and trichomes to attract pollinating insects.
The region of bud development is known as the cola. The bud that develops on the cola is often referred to as the calyx. Only the female marijuana plant develops buds that contain high levels of cannabinoids. The buds feature white hairs that age to shades of red, brown, and tan. The hairs are known as the pistils. The pistols on the bud are designed to hold onto any male pollen that falls onto the bud to ensure pollination. The resin glands on the bud develop sticky trichomes and terpenes to attract pollinating insects and deter grazing herbivores from devouring the buds.
The male buds only have pollen sacs that are used to fertilize the female and do not have the ample cannabinoids found in the female buds. Once a female bud or flower is fertilized the plant will put all of its energy into developing seeds instead of more buds. This is the primary reason that most growers discard male plants in an effort to avoid female bud fertilization.
