These got pretty tall on me but I had room for them to do that. I LSTed one that’s probably 4’ tall and didn’t get all that big around. No bigger around than the 15 gal bag it’s in.
Next grow I’m going to do individual scrogs.
With my expert opinion I’d say you’ll be fine, just defoliate enough to ensure you have good air flow through them all since they’ll fill up the space.
