just saw this pic yesterday. might be useful. you’ll want to get a jeweler’s loop, to see the trichomes. i harvest at 50% amber. they begin clear, turn milky (almost time), then turn amber (brownish) color. Harvest when 10% amber, more sativa feel. Harvest when 50% amber, more indica feel. this is due to thc degrading & turning into CBN, a relaxing & sedative cannabinoid. The strain has a lot to do with how uppidy, or couch-lock your harvest is. but so does WHEN u harvest.
