to be honest i'm not positive. i odn't have much experience with hydro. but with that limited light the space is just to big.

i was trying to offer a cheap solution to get more out of what you have. i guess if you got more light and used a hydro system and flowered (in my opinion) relativly small plants you could get a large yield from your 20 plants.

But if you use the same light i think it would be better to reduce the space that you are growing in with less plants fighting for the same light.

Ohh yea yea yea yea yea how big where these 300 plants??? the must have been like 6 inches or something. just curios. and it would be amazing t see it. it would be realy cool.
