Do I need more light?

[janjawid]

Im growing 11 plants in a 25 sq ft room. I have a 600w HPS. my last grow of ten plants was a bit of a dissapointment. I yielded aproximately an ounce per plant. I attributed this to the small pots (3.8 qts) I used and have since switched to 7 gallon containers. Should I add another 400W or 600w lamp. What is optimal?

Yes, add another 600. Each 600 is only good for 12 to 15 sq feet.

General rule of thumb is 50watts HID for every sq foot.

Another 1000.

If heat is not a issue, then I would add a additional 1000w.

I would add another 600w for sure !!! If you have an inline fan and cool tube add a 1000w. Really 1lb per 600 is what a lot of people
Actually get ... Depending on method used and time in veg/strain.
