Most growers harvest too early—and it costs them potency, flavor, and control. The real marker of harvest readiness isn’t pistils or calendars. It’s trichome maturity—and the “right” moment depends on your goal.
Clear trichomes = still developing
Cloudy (milky) = peak THC and a more cerebral effect
Mostly cloudy with some amber = heavier, more relaxing body high
There is no single perfect harvest window. Experienced growers read trichomes so they can choose the optimal ripeness for the product they want to create—whether that’s maximum THC, full-spectrum balance, or a more sedative profile.
This approach is explored in depth through our long-term education partnership with@Cannabis Training University (CTU) and in a new guest article on Ed Rosenthal’s Ask Ed blog.
