H.P.S LIGHTS/readme

HI everyone. I am growing 2 plants at the moment, and have six seeds that are nearly germinated. The light i will be using is a 400watt sylvania grolux dual spectrum, and im using 3 21 watt floros for seedlings (2 cools, and 1 warm). I would like to know whether i will be able to grow all 8 plants with that one hps light, and how much yield do you think i can expect?
Answears greatly appreciated, thanks

Im growing 6 plants under my 400 watt light I dont see why you wouldnt be able to do 8. Your problem will be when the 2 older ones are ready to flower what will you do with the 6 younger ones? As far as yield it to hard to say there are to many things to take in to consideration. What type of plant how big you let it get how much light what kind of nutes did you do anything to screw it up and so on. It could be anywhere from 8 grams to 4 ounces per plant.

yep what he said. especially it you super crop or use fim techniques to keep it short and bushy
