Organic Self-Watering Container Gardening

I have a lovely backyard but the wonderful trees also make for a good deal of shade and very late tomatoes! I learned how to make these buckets from watching some YouTube videos by LDS Prepper (he has a complete self-watering system - very cool). These are self-watering for up to 3 weeks, then you need to add some water. They are totally portable, move from back yard to front as needed for sun. Instructions for building are under the video on YouTube.
