i bought the 150W HPS security light from Lowes and did almost exactly what this nice tutorial told me to do: http://www.overgrow.com/growfaq/1151 except i made my ballast box very compact, and the bulb socket box as well. it works wonderfully and lights my room so bright that i need sunglasses indoors. awesome. its hard to take a pic as my camera is on my monitor but i will take pix if anybody requests it. now going to test my new airpumps and airstones. =D
