Floor space isn’t really the problem. The nutes are my tiedown for the LST. I think it’s the lights too but I keep the lights down within 2 inches of the tops. I even got a little heat burn last night. At first she was compact and then got leggy making me think t5 may not be intense enough. Anyway, I agree with yall. I will use 2 4ft fixtures next grow. I’ll upgrade from t5s when I use a few of these bulbs.
@dbrn32 can weigh in on this but IMO fluorescent lights are a waste of time. There are so many superior alternatives, especially for flower that you might want to consider switching. After all there is considerable money invested now, not to mention your time. Having a more appropriate light source will cut down on the plant reaching and getting “leggy” which is a benefit in a tent. You will also see much denser nugs when using a better lighting source.
I like the SCROG method but that is not really useful with autos.
