I’ve built mine with three wooden pallets and a wall. One on the ground against the wall, this allows the air to come from under and two on each side. I used tarp on the sides because they had some of the boards removed, but I have since replace the pallets
Whoooa, what a beautiful looking system. Pallets seem to have so many uses! How long does it take for your material to compost?
I usually pre-compost horse manure and then give them to the worms. So it takes up to two weeks. I first pile up and let it heat to at least 131F for at least 3 days, then I turn the pile and water it down and let it heat up again.
I don’t have enough other material for compost and the leaves in my garden are used for mulching. For compost I use the worms.
