Aztech Genetics auto Cheese Scrog

Plant is coming on well and there is plenty of side growth developing. bit hard to judge when to get the screen in for scrog but i think ill just get a little more height there on her and whack it in. as long as ive just enough room to comfortably work underneath the screen i should be fine. She could start flowering from week 4 so i want to have her filling the screen well before then.
