I have a 400 watt setup. One md bulb and one hps bulb. I have a 2 1/2' x 3' x 7' grow box.I have good ventilation w/ exhaust and fans. I want to know how many plants this would support.That gives me a little over 7000 lumens and 50watts per square foot of grow space. I want to have six plants, but am now thinking about four instead. Any help would be nice.

4 may be too much if u let them grow past a foot and a 1/2 the light will only penetrate the first 12 inches you can lst them and it will help alot and give u much better results as well

i didn't say it would be enough for 6 3 footers...more like six plants that finish at 18" to 2 feet and start flowering at 6-8"...:mrgreen::mrgreen:

better with clones..but yes you can do it from seed also..it can stress the plants some, but it works, I personally done it many times and never saw any stress or any problems of any kind...:mrgreen:

I'm gonna start flowering at 12". I figure I have 1 foot for the pot, 1 foot of space above the light, 18" between light and plant = 3 1/2'. That leaves me with 3 1/2 feet of grow space. If i flower at 12", I'll have 2 feet left for it to grow. Is that enough?
