// Definition
The glandular trichomes with a distinct stalk and bulbous head that contain the highest concentration of cannabinoids and terpenes. These are the primary target of water extraction and careful dry sifting, distinct from the smaller bulbous sessile trichomes found on fan leaves.
// From the Episode
Bubbleman explained that not all trichomes are equal. The capitate stalked variety โ the ones with the visible stalk topped by a round, resinous head โ are where the real medicine lives. These are concentrated on the flower and sugar leaves, not the fan leaves. The smaller sessile trichomes on fan leaves contain far less cannabinoid content. Understanding this distinction is fundamental to extraction: the goal is to separate capitate stalked heads from everything else. Screen size selection in dry sifting and bag micron selection in bubble hash both target the specific diameter of these trichome heads.
