Morning Camk, nobody knows when's the best time to harvest, everybody's got an opinion though, even if they have never grown but a couple of plants.
The more you grow ,the more you learn,but after years of trying to get the perfect harvest-effects ,just right, the way you want them, we always wait till we see a little amber, before we do anything, we sometimes even wait till we see 20-30percent amber, before we harvest, and in good soil, we don't even flush, and I would put our crops up against anybody's as for taste an effects.
