Just ordered a SuperLocker made by SuperCloset. Was initially interested in the larger units like those mentioned at the top of the thread, but as it is for personal use I figured I could go smaller. Should fit nicely in my bathroom. Four plants at a time will be enough...true subsistence farming!

There was a Thanksgiving special and I can pick it up nearby for no shipping cost.

What really tipped it for me is I have surgery coming up and will be one-handed for some time so construction isn??t in the cards right now. Won??t get it unti the end of the year though, but I guess the holiday season will be busy enough without starting a new project.
