Temp

my setup is at about 79 degrees F is this too hot? i dont have a fan either, is that necessary? do different plants want different temps?

79 degrees is fine. You'll need a small fan blowing GENTLY across the plants to simulate the moving air of the outdoors. This will strengthen the stems by slightly stressing them. Think of the weight room ... light weights and lots of reps.

should the fan be going 24/7?

It doesn't have to be. It can be on the same timer as your lights.

should it be blowing in the light or the dark?
