This was made with a USPS box and lined with tin foil, shiney side facing in towards where the plant will sit. This light rig will be mounted in a well enclosed cabinet. I used a normal light socket and stripped the end of a computer power supply plug with a ground wire and rigged it up accordingly including the groundwire. Everything will be kept inside this cabinet and I will make a bigger reflective housing as the plant requires. I will post pics of the completed rig sometime tommorow.
