With cfls its pretty much saying that a 23 watt cfl gives out the same light as a 100 watt incandescent so you have to go by the 23 watts. So you have 345 watts for that big of a space people are going to tell you you need more. Your getting about 14 watts per square foot most people recommend atleast 30-50. Anyways you should be fine with just adding a couple more 2700 k lights above the autos. Ok bro. Thanx for all the info. I really appreciate it. I'll throw some warm over the autos and add more daylighting in. Thanx again!!! Happy smokin!
