"Topping" your plant

wow, thats awesome. how come I had never heard of that before? do you replant the top as a cutting? or do you just use topping as a way to bush the plant out and get more veg growth? my seed growns are about two feet tall and seem kind of stretched this seems like the perfect thing for them... becuase their getting to tall for my own good

cut the absolute tippy top of the plant. not enough to clone. just enough that the tip is gone. about day 3 noticed that new growth was forming and the cut had healed alot. about 2 weeks ago is when i cut the top. and from the old cut there is 2 new "colas" about 9" tall now.
