Yes the block walls on the sides are underground, block wall on the back is sepereating the garage from the basement. The veg room will be against one of the outside block walls (underground) and the basement seperating block wall to the basement.
I see ones that take those little camping propane canisters, I assume your talking about something that hooks up to 20pound grill tank right?
Heres round two of progress pics (forgot to tag you in previous post update). Near done now, just have to put foam board insulation on walls and floor. Then will figure out if im going to just put panda film up or something else. I fired up the heater and after a few hours it got it up to 70 degrees so im a bit woried it will be hard to keep warm with jus the 1500 wat oil heater when its colder in the winter. Not sure how much of a difference insulating the rest of it will make.
the spray in stuff is only good if it’s closed cell foam which is only possible with a actual foam sprayer- not the 10 dollar “great stuff.” You would need to pay someone to do it for you. It is the ultimate best insulation. But it isn’t worth the money.
Would need a lung room to bring the cold air in and treat first.
That's the garage
Fair enough. Garage lung room would work. If the temp gets too low in the garage I’d look into some mild insulation over the garage doors.
