I run a piece of PVC through my compost to get air to the inside of it. I am wondering if there would be any benefit to running a piece of pvc with some holes in it, wrapped in a screen routed under the soil and then going out the top.
Youd be better off just using a smart pot Id think. I think other people airate by using a thin piece of bamboo and repeatedly jabbing small holes in the soil, but I've never done this myself.
