Step 4: Construction: Erm.....constructing It!!
This step is fairly straight forward.
Take the glue and haphazardly glue the LED's to the lid of your container of choice then plug it into a power supply and hope nothing blows up
(DISCLAIMER: its not my fault if anything blows up.)
when nothing does blow up let out a sigh of relief and relish in the futuristic glow of your new LED grow light system!
(Note on voltages: for the set-up i'm using i found that 7 volts was adequate to light all the LED's and for nothing to get too hot, and for the current consumption to be adequate. YMMV. i strongly suggest using a variable power supply to find the optimum voltage.)
