I also use a plastic shoe box but I never thought about using the clay pot as a waterer. One trick I do for extra tall cuttins is; I push all the media up to one side, leaving about half the box media free. I then stick my cuttings sideways into the cliff of media. When they root they tend to be lop sided but they straighten out once you plant them upright.

Has anyone tried this indoors? I have many tender perennials I'd like to take cuttings of to overwinter.

What window exposure would best approximate outdoor shade?

Thanks kayjones for bringing the thread back to our attention.
