hey there, trichomes take about 2 weeks to go from clear to cloudy, but from cloudy to amber is a question of the degradation of the outer membrane of the trichome , so that can happen quickly even before it's milky or in the right conditions never happen at all . Main determinants are air flow, heat, contact, and humidity . the moment there are no more clear trichomes that's when you're at maximum potency in terms of THC. Hope this helps ! ๐
