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.
Inexpensive Mini Greenhouses - These worked PHENOMENALLY for seed starting this year. It was nice to be able to easily carry them all in when there was a frost warning. I kept the lids on during the day to keep heat/moisture in. Love this idea!
