If you mean the self watering container, my guess is that there are many varieties of worm in the garden, with varying habitat and food needs, so worms might not work out. For instance, Earthworms cover a lot of 3 dimensional space. Since earth trainers are attempting to create an ideal environment, issues like aeration are addressed in the growing medium. You could throw in red worms, but they need material to break down, in which case aged, hot composted material is best.
Left long enough, worms will work their way into composters anyway, even after sifting there may be a few.
