I have a hermann's tortoise that just turned six months old and about three inches long that I was curious when to move outside. I am in the PNW so it's still pretty chilly and wet however his indoor enclosure is only 2x3 and I want him to have more space. I found an 8x3 greenhouse cover I'd like to put in my raised garden bed until he's larger. The garden bed is 3x18 feet long, so in the future it will all be his. Can I take him out during the warmer times of day or will that stress him to go back and forth? Any feedback would be appreciated.
