Thank you to Homestead Survival for this link to the original site over at Frugal Dad.
I plan on doing this next year. I've got all winter to get things set up... including talking the roomie into thinking it's a good idea lol.
I've done some gardening in a pot and that worked out OK. I've still got mint growing in one of them and had some good success with tomatoes. Looking forward to trying this as well.
