Its going to be in the middle 30's tonight. It was just 80+ degs the other day. I may go streaking with my socks on... But my main question is, if my moms are in a closet in the garage under leds, should I switch it to hps, like 400w to keep it hotter? Its not going to get colder than the 50's in there, i dont even know the rule of thumb for cold weather since I never get any and always grow inside.
