@Growingkitten, I do, I use two 325 W CMH lamps. My area is 3 1/2 feet wide by 4 1/2 feet long. This is obviously plenty of light for me because I have light burn the tops of my tallest spears. I bought inexpensive lamps would knock off cheap bulbs. One of the bulbs went bad and I replaced it with the Phillips Bulb. Phillips Buldburns brighter and whiter . They are both 3000 K. It pays to go name brand
