If you've got 8' of height, a 400 hps is a better choice. I like farmtek cfl's for growing mums and small flowering areas. Yet, If you have that much height, there is no point in using a cfl unless you are going double decker. Don't!!!
At 100 watts of HID per square foot, you can do some amazing work.
lmdesade Reviewed by lmdesade 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
