This weekend I had planned to add cloth wicks to some and redo the potting soil for others, as an experiment since there are some duplicates in the mix due to purchase of six-pack transplants.
Ended up leaving everything alone at this point. Roots had grown through the drainage holes of the inner bucket into the reservoir, despite 1-2" air space. Didn't want to risk disturbing the roots and the plants all recovered and look super healthy, so I did not redo the potting soil. As far as the cloth wicks, I couldn't get them into the soil (attempted to jam them through the bottom drainage holes, goal about 2/3 up into the soil).
Oh well! Now comes the part where we wait (some fruit already begun to set!). Ugh
