Hi everyone. First I'd like to thank everyone who has experience and shares it with those of us who don't. I've done quite a bit of reading so far. One thing I'm having trouble finding is what brand of lights people prefer. There are so many out there, and prices range from $20 clear up to almost $200 or so. I think I will be running a 600w in a 2ft(depth) by 5ft(width) area, the height is 8ft. I've been told the height doesn't matter too much. So my first few questions are, 1.) Would a 400w be sufficient enough for that space?(I will be doing SOG). Or will it be worth my while to run a 600w. I assume the 600w. I've attempted to figure something out on the brands, but it's difficult for a 1st timer. Sunmaster? Eye Horilux? Solarmax? Any help would be appreciated. Thank you very much for your time and help!
