Another noob grower question. As I have stated in other post, I am pumping AC into my grow box which is working great when the lights are on. The problem that I have noticed is that when the lights are out the temp get down to 60-65 degrees. The AC is a window unit, so I am trying to find the right setting on the thermostat for both lights and no lights.
So i guess the real question is how cold is too cold??
thanks in advance
