make sure temps stay 75 to 85. I have had it up to 90 degrees. It depends on the strain. Make sure you have the proper ph equiptment and stay around 5 to 6. I use botanicare nutes. good stuff. for clones don't use the 400 hps because it would be a waste of energy. get a couple compact flourescent and you are good to go there, then you won't need those big ol fans.
