Hick said:Amber trikes are the first indication of thc degredation. "IMHO" 80% would be a bit over-ripe, but you should experiment. Try some at 20%, some at 50% and some at 80%+. See what you prefer.
The earlier you harvest, the more "heady" the high, the longer you wait, the more "body" stone. Depends on personal preferences.
