i was going to go with a Mh/Hps combo light/balset just unsure on the wattage i should use im going for 3 plants.. should i 240/400 or 600 watt setup? And also for ventalation would a basic intake/exaust be good enuff>?

Thanks in advance!
My current closet is about the same volume wise... I can keep a 400w in there with a cooltube and 129cfm inline fan. The temps are on the high side but within range so... it's possible with the proper ventilation setup. I'd aim for a few more cfm's though.

For your dimensions it might be better to have 2 x 250w hps/mh in line like elskeetro's pic... but the growspace it's that great... ya know? Any chance for another growroom???
