some of us prefer harvesting when the trichomes are 'cloudy' and only 20%-25% trichomes start turning amber or brown ... reason being, as the browning occurs, some potency is lost, and the 'high' will be more and more of a body high, due to THC oxydizing/converting to CBN (cannabinol), which has only 10% of the psychoactive ingredients of THC ... the reason I harvest a little bit earlier, I try to dry and cure properly, and the trichomes will continue to darken even after harvest ... hope that helps ( I get my technical info from Mel Rosenthal's books, I highly recommend everyone has one, and read, read, read ) ... :smokin:
