Oops, should have addressed to FMD, not Dom!
Thanks for the pictorial on self watering containers and your procedures and techniques. From your post you say "Some people grow figs in these things with wonderful results. I find the roots to be too aggressive that soon occupy the entire water reservoir."
My question is, what's so bad about the roots occupying the water reservoir? I'm thinking as longbas the plants are healthy, growing and getting thir water, does it really matter if there are roots in the reservoir?
Again, thanks for your info.
