What is better?

I am going to use four 400 watt metal halides on a track in my flower room

What would be better :

Three 4' x 4' tables or Four 3' x 3' tables?

Three tables I could do a 6, 9, or 12 week strain

Four tables I would do a 8 or 12 week

hmmmmmmmmmmmmmmm. . . . . . . .

go with 4 3x3 tables more light to the plants and try and use HPS if you can its a lil more lumens

I am not worried about lumens. I am going to water cool my lights so I can place them very close to my plants. I want to use Metal Halides because of the over all better spectrum. I'm not using a veg bulb. I'm going to use a warm halide or the Hortilux Blue. I have switchable ballasts so If I get crappy yields I will change back to HPS.

ok well thats good... i do know ppl that grow with 1000 mh and have goods yeilds... are you trying to do sea of green? i myself would just do that... how many plants are you talking about here?

Water cooled, Air cooled, You can't get as close as you think. Water cooled is just too much of a headache.

Not really. Very easy to do. I am a damn good plumber too. Way more effective @ heat removal then air. A 400 watt halide will have almost no heat at all using a chiller. Chillers are cheaper to run then AC.

Hell yeah SOG. A nice veg room as well. As many as possible. 12' L x 4'W x 6'H room. I am planning on using C02 and a climate controller.
