Jenn: Nebraska?, I grow some bulbs under High Intensity Discharge lights. I had a stainless steel tray made about three by four feet with a 5 inch side. I put a drain spout on one side of the tray and placed a cork in it so I could drain the tray if that was necessary. The light manufacturer will tell you how far the plants have to be from the lights. I doesn't seem that the light is to expensive to run. We purchased a new refrigerator at the time I purchased the light and the saving on the new refrigerator was about what the light used. The larger the light (watts) the greater the growing area. I use a metal halide bulb and there is also a sodium vapor one. The colors are somewhat different and the manufacturer can educate you on that. I keep the light on ten hours per day and water so that the water runs through the pots and two inches of the stainless steel tray are filled with gravel. So it is a very big pebble tray. I have had narcissus romieuxii flower as well as various tender arums. The arums were somewhat of disaster due to the scent when the flower opened. Arnold
