The LED's are five each of HGL's 336X-PRO arranged in a five lobe circle, outer diameter is seven feet. 38 square feet of grow area.
The surround is 48 each four foot T8 tubes, 22 of them are Reptisun 10 (10% UVB).
The balance are 14 Florasun and 12 Reptisun 2.0 (2% UVB).
Also 24 T5's, four of which are ArcadiaD3+ (12% UVB). These gave both myself and a trimmer sunburn.
The balance are 16 Florasun and 4 Redsun.
And dead center I have an actinic HID for all those blue wave lengths the LED does not provide, 404 nm through 440 nm.
Total wattage is 5232 for 137 watts/square foot. This replaced an HID room of 133 watts/square foot. The plants grow more rapidly now. Temps are kept 82-86 days and down to 63 at night.
Sunglasses are outside the door, extras for visitors. Glasses are a must, UVB levels are double a tropic meadow in the summer, note comment on sunburn.
The plants being harvested now were started in the HID room, first complete LED plants are due 03-10-12. Or thereabouts, this room grows somewhat differently than the old room.
This room is based on a year's worth of note taking in a full time test budroom. I spent my whole entire allowance on this room, I sure hope it performs to spec.
Big smile every time I walk in there, it feels good.
