Grow room to cold

use a heater pad to control temps

attach a temp controller or use a thermostat

eases ur worries

good luck
 
I'm in Colorado and do year round grows in a crawl space. Sometimes it gets down to the 50s when the lights are off. I have never had any issues. But if that plant happens to have any colors that are going to come out like purple. The cooler temperature will really bring em out. But if you're really worried about it reptile heat mats work
 
My lights on, night time temps are 71* and lights off, day time temps are about 62*. You will be fine but I would recommend getting a dehumidifier in there and keep it about 55% rh to avoid mold during lights off!

Cheers
