Growing in my garage

I want to get one of those new tents that are 10ft long x 10ft wide x 6.5ft tall the only room large enough to put it would be in my garage and I wanted to know the best way to insulate it to keep the temps from dropping too low in the winter and getting to hot in the summer

That is going to depend on where you live.

well your walls should be insulated already. all you can do is insulate the garage door. one way is to buy a new garage door thats already insulated. another thing you can do is frame in the garage door and insulate yourself. or if you have a buddy that does the insulation spray foam you can have the inside of your door sprayed but it will probably get messy

if your not going to use the door cover it with plastic.

How hot/cold does it get where you are?
