For my herb garden. This one doesn't show you how to do it but looks like a good project to start! It's also great for a tiny patio or yard. Looks like the pots might be too small though. so, build frame bigger according to pot size preferred.
I think this would be a neat idea for tree-stumps remaining from downed trees, (which we have some taller ones not yet removed), to use for a plant stand, maybe with a solar light at the top. Nice idea for somewhere in the garden too!
