couldn't have said it better myself(Y)kiss-assyou harvest when the pistols/trichomes are fully developed, when the "resin" on the buds turns from white/clear to brown/amber. a crappy $20~ handheld 100x microscope can realy help when it comes to perfect harvest timing. trichomes usualy amber-up fast, like within a day the whole crop will be primed(the harvest date). after the trichomes turn amber plant growth stops and air moisture starts to degrade THC.
