As above says,I use to top quite a bit from cuttings but since ive done seed ive been scared to as they look so weak compared to cuttings. I have done supercropping/LST on main coa arms,I aint got a picture to hand but my 1st 2 node cola arms are the same thickness and height as the main cola except they are further out from the plant like a xmas tree,I can see a good 6 main colas off the skunk#1 I have and a good 4 off the blue cheese which people say doesnt yield alot,I can see easy 8oz off each I will update my journal,will need to check my profile as its not in public forum. They are worth doing,I will only top if they get to tall from now on as the supercropping and LST have done what topping would do. If you have no room id say do it on SOG. Trust me its worth doing,if your going to top make sure there well built before you do so as I recon on seedling it would stress the fuck out of em. take care
