Over 2lbs from 400w in normal time frame, need a test pilot.

if i get caught im fucked wether i have 3 plants or 300 so its worth it to me if it really works....i see people saying finish in 2 months how is that possible. my plants seem to take 5 moths to finish at least.

You'd want to use a fast flowering strain and no veg time. You could even clone in 12/12. The idea being that you need very little yield ea, to produce a very large total yield.

I'might try it, if it were legalized, but a vertical could probably work as well , if not better for the same square footage.
