Hydrocoil

For anyone using incandescent type bulbs for growing you might consider the Hydrocoil to cool the bulb off. You have two advantages by using it: It will cool your bulb so you can place plants right next to it without being burned, means you can use a lower wattage bulb with less electricity. Also you can use the cooling water, which will be heated up to heat water for fish if you are going to raise them. You do need to use a slimmer type bulb for it to work. Another disadvantage is you would need to clean it a lot, unless you use distilled water as the coolant.
