all lot depends on that,point.how bigs the plant how dry was the plant 2 days before he is gonna take it down,because if they was dry then then the plant may dry to fast ,in a room with a hps light on it ,they can become brittle on the ends of the buds through heat.honest far better either bag drying fast ,to me I have never done it I like to leave it to dry in the dark with fans on it,but try and tie the plant so it does not twist in dry area or you are losing thousands of heads falling of ,unless you are in a situation you have to dry fast ,just take it easy ,there normally ready to jar after 7 days of drying then jar,but burp the jars,leave a month or so then smoke.I'm on my last bit of livers x cheese at the minute,but still have enough oil left.
