Krimez, sup man. Plants look great dude. I don't know about you guys but the closest I can get my 400 watt is 10 inches without damage to my plants. Even with strong fans on the canopy the leaves will begin to curl at the sides from heat stress. However, I can get my 600 watt about 7 inches away. Why? It's all about the reflector. My 600 watt is aircooled and there is a layer of thick glass between the bulb and the plants. So I think your reflector and overall setup will really determine how close you can get the light. I don't even keep my lights as close as I could because, like Krimez, I need to cover a wide canopy.
