If the research is lacking and you have the motivation and the lust for more information to be out there you could do this experiment yourself. This would help you see for yourself what works best for you and along the way it may help inform others who are in the same situation as yourself.
I would be interested in your results.
Well, I'm pretty much doing that with my current grow! I'm not removing anything below the scrog netting, except when the lower leaves become very yellow and pretty much fall off themselves. I figure at this point the plant has drained them of their nitrogen etc., so in fact up until then they have been providing the plant with extra nutrients which would be lost if I trimmed them! Hence my skepticism.
I am going to see how this grow goes, and thoroughly analyse the results in terms of yield and bud distribution. Then, maybe next time, if I think I can do better, I'll try a grow which I will trim. Not strictly 'scientific', I know - but it will be amusing to see what happens.
The only thing that really worries me is mold. Removing the lower leaves might be beneficial for airflow, particularly if they are very bunched up under the netting. Right now, mine are pretty well ventilated so I'm confident I can run the grow mold free (fingers crossed!).
I grow on a small scale, one 400w hps. I kinda like the popcorn buds because it gives me more trimmings to mix in a cookie batch.
Yeah, I feel the same way: It's aaaaaall good, man!! 8D
