I got in touch with a couple of local restaurants (friends) that will hold 5 gallon buckets for me, starting now. I'm going to try some self watering containers since I see a lot of advantages with it. With the buckets being free, I can spend a few bucks on the stuff needed to build the SWC. The proper pots are just too costly when you need more than 50.
Based on your experience, will the 5 gallon buckets work for a couple years?
