Also the side branches I'll need to tie up so they have better vertical growth and they don't grow on top of one another, is it possible to use cable tie's or will that stunt its growth,I've done a lot of leaf tucking so there's a lot of light penetration, also i don't want the side branches to be weighed down too much and I have an awful feeling this will happen,not that that's a bad thing at all, I just want the best for my ladies ) any advice is welcome
