Hey Lindberg, I stopped into my fav dispensary and spoke to the grower. He said I can top down as far as I want but need to remember the more I cut the slower the recovery. I bought some rooting material and I'm going to do a big topping on my two Sativa's and try my hand at cloning them at the same time. More to come my friend. I sent you a private message with my email address if you're interested in emailing also. If not no problemo.
