Ok here's the link where we got our idea
@Dinu,
@Damian . We tweaked it and used metal barrels. Being we are in the mottled shade most of the year, anything that attracts heat like the black color works to our advantage. The posts are in cement about 2-3 feet down. We put a trough between the two so we could collect Compost Tea to use in the yard
@TomPNW. But most of the time it evaporates before I remember to use it.
It doesn't compost overly fast seeing how we are in mottled shade. I have never added anything to it. When emptying the barrels into a wheelbarrow it tends to spill on to the ground some so be sure you don't plant anything tender around it. Contemplating planting a Giant BOP to the side of it since the GH will be next to it. Kinds sort of like to soften the edges so that it is just not sitting out in the open, you know? But might get in the way.
Still thinking on that.
