I'm planting most of my garden in Earthboxes this year
I'm a huge fan of the Earthbox. My best crops of tomatoes, strawberries, peppers, and corn have all been from these wonderful self-watering containers.
I really like gardening in self-watering containers. I have made my own, but after a number of seasons, I've found that that the Earthbox-brand, commercially produced with plastics that last in the outdoors, last a lot longer. There is also no guess work with soil vs. reservoir depth.
I've ordered 4 new Earthboxes to compliment the two I have been using for nearly 10 years. The best tips and tricks I can offer for container gardening are to simply follow the directions from Earthbox. I've bought a few books, I've scoured the interweb forums for info, and honestly nothing has helped more than doing it exactly the way Earthbox suggests.
I may try some of California's newly legal recreational plant in a box as well. Who knows, everything else likes to grow in them...
