Need Heating Help

Hey yall, been a long time since I've been on here. Im finally back in a space where I can garden and super grateful for it. Im just running into a few issues.
Im located in a area that gets quite cold in winter 10F and having to grow in a garage space.
Im currently setting up a 10x10 tent and a 4x8 tent. I am using a exhaust fan that kicks on for 5 min once a hour to pull the air out the garage. Ive been having issues with moisture in the garage due to snow melt I believe. Im hoping these sandbags I got to put in front of the garage door will help.
When the lights turn off im currently seeing like 53-60F in my 10x10 tent.
I have thought about having the light cycles offset between the 2 tents so one is always exhaust hotter air into the garage to help supplement. I have also thought about hanging moving blankets in front of the garage door to help insulate it better.
Im curious as to what methods yall would recommend I do to help the temps in winter.
Im excited to see how easy it is when summer hits though

Is the garage insulated? really gotta watch for condensation with temps that cold.

yep it is insulated except for the garage door i believe

You'd probably be better building a sealed room and having co2, dehumidifier and heaters if your in a cold climate.

I'd imagine having a exhaust running only 5 min will leave your humidity sky high once plants are big, you'll end up with water running down your tent and garage walls

You will need lights off heat at least an a 70 pint dehuy watch that door if water is condensing on it run a fan on it 24-7 or it will be dripping= mold.
