You can use the top and make a clone,I've done it before,also I always top my plants,I just recently harvested a plant that had almost 40 to 50 tops,no shit.I top my seedlings first,after the second set of leaves develope,and I have a trick to where the main stalk still remains.So instead of the usual two split tops,I have three.I then top those three,which makes six,and so on.The plant turns in to a little bush,and grows outward instead of growing tall.my plant was only 2 and a half foot tall with that many tops.but,she was wide as hell.I have a new plant that I'm applying this tecnique to.I really need to get a digital camera so I can post the pics.Another thing is the stem gets really thick,and the plant is more hardy.A hurricane couldn't even budge them.I always top my plants.I can't remeber the last untopped plant I grew.Topping is the way to go.It really does increase yeild.So,everbody top those girls,not once but multiple times,and watch what happens.PEACE
