As long as they are going in-ground, no worries over rootspace. No big deal not cutting them. Early-on I tried finishing in 3 gallon pots, cutting just a little of the roots, and right back into the 3's, thinking I could up-pot into 5's just before putting them to flower. Ran out of rootspace about 3 weeks into flower in the 5's and had to go get some 15's. (why don't they have 10 gallon nursery pots...?)
Anyway, it screwed-up my entire schedule because they took up so much time and room. That's when I started the severe trimming-back, and has been working for me ever since.

Perhaps practice cloning with a couple of expendable shoots. A little practice goes a long way.

Looking great. I might have gone for more side-branching and lighting to pull side branches away from the cola's, but I'm sure they'll do fine. Success feels pretty good, eh? :thumbsup: :thumbsup:
