I keep my 1000w about 8" above and to the side of my canopy but I use cool tubes too. I like more side light then top light but that's just me. The plant does not need the light directly over the top to grow. I alos use more light bulbs then most people to too. One on each side of the plant for full coverage.

You got to ware shades to walk in there.
Zandor Reviewed by Zandor on . KEEP the LIGHT CLOSE It is KILLING me to watch people grow and keep their lights so far away from their plants. If you are going to invest the time, money, effort, and risk into growing YOU should definitley keep your HID lights as close to the tops of your plants as possible. This means, you will need adequate airflow. Exhaust lights and keep oscilating fan between the tops of the plants and the bulbs. I have been visiting a few garden in Northern California latley and the growers have their lights 16-24 Rating: 5
