I've done some research, now I'm seeking experienced consultations /
opinions. My current growroom is 54" long, 30" deep, and 68" tall for a total of 76.5 cubic feet. I have an exhaust fan rated at 70cfm installed in the ceiling and an air intake at ground level. I'm currently lighting with a dozen cfls at mixed wattages from 27-42 watts each and seem to be doing pretty well. It's just irritating having to raise the lights on a daily basis to keep the leaves from grabbing hold of 'em. I want to switch to a mh/hps system and found a 400 watt switchable system here: Grow Light Kit- 400W HPS MH Digital Ballast, Full Spectrum Bulb, Reflector (sorry if the link stretches the screen) My current temps in the room stay at around 76degrees f at plant level, and never rises more than a degree or two max recorded temp. Humidity stays at 30-40. Will this be the way to go or am I aiming low to keep my lighting system under US$200.00? Will I need additional cooling? I know I've got about 8 or 10 degrees to play with before I've gone over the maximum recommended temp. Thanks in advance guys. |
