Everything I have read about temperature control was about cooling down the grow box. I need to keep it warm.

My only ideas are to have the exhaust at the bottom of the grow box so it pulls down the heat from the lights and warms it up. Maybe I could insulate it somehow. I would keep the lights on at night when its coldest outside to warm up the box and the lights off during the day when its warmer.

I'd really like some advise or suggestions on how to keep it warm enough.

Also, would using a carbon filter for the exhaust take away the smell. It would be best if my parents didn't find out
this will keep em warmer

and if you dont wanna make one or ten of those grow boxes i would suggest getting a heat blowing fan. you can pick one up at home depot. it has a reflective backing on it creating heat and blowing it amongst your crops. is the garage totally free of light leeks? Having the light on during the night would be good but having it off during the day when you want it dark and having light get in there wont be good when it gets to flowering.

oh and this will keep the odors out if properly made/ sealed up
