Hi, if anyone can help me it would be appreciated. I have two gavita 1000. They are around 12 inches from my canopy. I have no problems with temps as there is plenty of air flow. I only have them turned up to 850 watts at the minute. As long as I can keep the temps in the canopy down I'm going to turn them flat out to 1150 watts. Is this a good idea or can you have to much light?. Thanks for your advice.
