Definition - What does Glandular Trichome mean?
Glandular trichomes are the glistening resinous crystals found on about 30 per cent of a mature female marijuana plant.
The word trichome comes from the Greek word for hair because they resemble little hairs. The trichomes are a special part of the plant because they are what produce, hold, and secrete essential oils. Glandular trichomes contain the majority of the THC, cannabinoids, and terpenes of the cannabis plant.
Although the leaves contain small amounts of THC, cannabinoids, and terpenes, the trichomes are the powerhouses that holds the most of these materials. Glandular trichomes also serve to protect the cannabis plant from pests; the pests do not like the taste or the smell of the trichomes.
Hydrolife explains Glandular Trichome
People seek glandular trichomes because of their potent concentration of THC. They are the primary component of cannabis products like kief and hash. (Kief is a collection of the heads of trichomes and hash is a trichomes extract.)
Trichomes are very small and develop on the leaves, stem, bracts, and flowers of the plants. Throughout the growing process, glandular trichomes will develop. Their color will change slightly, depending on the strain, indicating that it's close to harvest time.
There are two main kinds of glandular trichomes: capitate stalked trichomes, and bulbous trichomes. They serve the same function, but their key differences are their sizes; capitate stalked trichomes are large, and bulbous trichomes are small (shorter).
Glandular trichomes are present from the early life of the plant and some later develop as the flower is maturing. Glandular trichomes are very fragile; they can be brittle and break off. If the plant is being grown outdoors, then large amounts of rain or mud can wash off the delicate crystals.
