space is my problem, hence why i was trying more plants in smaller pots. im trying to find the most efficient way to a healthy yeild with only a 400W hps and a 4'X5' setup. if i can produce more with only 2-4 plants in 5 gal pots then ill never go back to smaller pots. but i do know that these size pots are perfect for smaller, thinner plants up to 4'. ive seen WAY to may growers using these pots with great success. all im trying to do is find out first hand which will yeild me more. i honestly thought that more, smaller plants would be more efficient(acting like a SOG), than fewer, bigger plants. so thats why im trying this first.
