>>15928502Yeah you can make em out of whatever works. I just cut down trees and milled 4x6's. Did that Nordic old logs shit in the bottom. They hold heat, so you get 2-3 weeks early start, and 2-3 weeks extra in the fall. Which is important up here in canada. Keeps the rabbits out. Still have to trap racoons and shoot all the squirrels. If you have the free materials build em. I can't imagine the cost to buy this crap
