With 400 watt HID lighting you will most likely need to vent to the outdours. Also the big fans to move air will not be stealthy, if that's important to you. What about odor control?

And by the way, everything will NEVER be perfect.
Opie Yutts Reviewed by Opie Yutts on . a light question :smokin: ok so i just want some feed back on these enviro lites. im thinkin of gettin 2 of the 200w as im really intregued by them after doin some readin. I know they're cfls and most will say stick with mh/hps but apparently they have a higher lumen/watt output than other lites and the light it gives off is 100% par which is grat for plants, right?? and as they are cool running they can be placed right on top of the plants so the lumens arent lost over distance. so guess im just lookin Rating: 5
