I do have to say I thought I'd save alot of heat with this light? (1600) Not near what I was hoping for. The hard thing,, is it isn't ventable. Unlike my air cooled hoods with the HID Magnums. The radiant heat infront of the lamp is less than the 1000, watters,, but the hood is only 5 degrees cooler than my HID hoods. And if I was to run ductwork on my HID they wood be abit cooler than the LED light is...........
I still haven't started the side by side,, LED/HID. Temps have been up to close to 100 outside. But I'd be starting later this week I think. Next week will be cooler. Least afew degrees... The grow will be clones all of the same parents, age, pot size, and food. I'll be doing 4 under each hood. I have heard good things about these lights. So I have to see. Well I been setting this up for afew weeks. It's ready to kick off any day. Anyone is welcome...
Sorry to chime out. Hope all's gardens are green.
