Hi - i cut a IPC Tank in half and made a couple of these. Here where my steps to account for drainage and want to get your suggestions:
1) drilled 10 holes, 3/8" around the outside bottom
2) filled the bottom 2" of the empty tank for 1" gravel
3) laid black landscape fabric over the gravel
4) filled rest of tank with topsoil on top of the landscape fabric
In addition i obviously painted the plastic with spray paint to provide UV protection. It's about 22" tall.
Good?
