// Definition
The largest and most cannabinoid-rich type of cannabis trichome, featuring a visible stalk topped by a spherical gland head containing cannabinoids, terpenes, and flavonoids. These are the primary target of hash makers and the source of most resin in high-quality extracts.
// From the Episode
Bubbleman discussed the three trichome types in Episode 011: capitate-stalked (the large ones hash makers target), capitate-sessile (smaller, sitting closer to the leaf surface), and bulbous heads (the smallest). He described how looking at the length and growth of trichomes under macro photography helps determine harvest timing. The panel discussed how different lighting (LED vs HPS) affects trichome head growth.
