I picked up a sunsystem 250w HPS lamp yesterday for $75 on craigslist. It's one of these ballas/reflector combo lamps. It works great but when I get it down close to my plants, say 12 inches from the top of the soil, the temp reading right at the top of the soil goes to 95 degrees. Is this pretty normal or should I be looking to move the lamp back further? I had it 3 or 4 feet up over night last night and temps were mid 80s. To get an idea of how the temps change further from the light I put the thermometer on the floor and got 89 degrees, so 95 at soil level with light 12 inches from dirt, and 88 on the floor, which is about 10 inches lower than the soil. I can't air cool this hood without some extensive work, it has no vents on top to put a flange in. It also has no glass, but it does have rails to slide glass into. Any thoughts? If this is normal with a HID lamp then I'll just let it ride like this. When the plants are taller it would only be the very top that is in that kind of heat. I'm sure everyone deals with this problem....I'd just like to know the best way to handle it. Thanks!
