Ideally you only want a 10 degree shift in temperature from the light on cycle to the lights off. How warm does it get with the lights on? Can you put your AC unit on the same timer as your lights?
byrdog55 Reviewed by byrdog55 on . How Cold is too Cold 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 RockLobster4040 Rating: 5
