vertical garden - "perfect for herbs - this makes more sens than the tower I was planning - add a grow light and place in your garage during the winter - build with bottom and put wheels on it for moveability" Nice idea!
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.
