Hi,

The temperature fluctuates from 78-84. Yes, the 400MH puts out the heat! It's all I have to use, so I have it up about 3 feet above. I used a drop of superthrive in a gallon of water and have fed them a small amount for two days. The slow grower is now beginning to veg, with some small, but healthy leaves. So it think it's going to pull out.
