Have a woodshed coming next week. 6'w x 12 'l x 7'h. Venting along the ridge line and an all metal roof. Had a friend at work tell me I could probably put fresh cut and split wood in and it would be ready by winter. He guessed the inside temp would easily hit 120F. I plan on putting a thermometer in it. Any guesses at to how hot it will get inside??? Thanks
