I came across this video today and I must say it is one of the best videos I've seen on how to know when to harvest your plants. Dude is spot on and he really explains things well. Everyone likes a different head from their smoke and this guy lays out exactly how to know when is best for you. Well done indeed. Hope it helps. BTW.....wasn't quite sure where to post this....so if any mods feel it can be better placed on the forum...please do so.
