well having your indoor grow being equivalent to the sun is essentially impossible. As OpenDNS pointed out a greenhouse grow would be better. I suggest you study up on lighting to understand the different points. I have achieved 1 gram per watt under a single 400 hps. More skilled growers can achieve 1-2lbs per 1000 hps or a pound per plant. Which can be done in way less than an m2.

You better believe the yields are "gassed up", nobody ever tells you how they got to those yields. You could easily do better or much worse, depending if you know what you are doing...

I normally add up to 1500 ppm of CO2....the difference is amazing. My yield is much greater when I do.

No kidding? How big an area are you talking kitty?
Thats interesting.

Well thank you Lacy

i like to think i know what im doing, dont know if do, but i havent come close to a pound per plant! i grow like 24 plants under 8 600watt lights, and the most ive gotten was a little under 10.5 pounds. but im not using co2, and i grow in dirt, i only use organics, so i know im losing some compared to like areo growers with $400 dollars worth of chemicals! but im satisfied. plus is totally natural. do you have any advice on what i could use to get my yield up?
