2 or 3, just depends on when they get ready. watch for those new pistils to draw up, the swelling to stop, and the trichomes to turn at least mostly milky. i won't cut a plant if i'm seeing more than a few clears. if i want it to be heavy duty, i wait till i see at least 10% amber trichs. some strains don't amber anymore, been bred out, so i just give those the same amount of time, roughly, and hope for the best
