I've read about a method - never tried it - of draping a strip of cloth
from a container of water onto the soil. Supposedly the water wicks
from the container down onto the plant. Doesn't sound reliable.

If I were to devise a method, I'd try rigging a small pump, on a timer.
Micro tubing like used with irrigation systems outdoors might be ok.
Put plants and the whole rig in garage or shower (where spills won't
matter). Could even use a submersible pump, such as is used for garden
ponds. There is probably a ready made thingy for what you want, but
have never seen one.

Dedicated RV'ers take the whole house with them - picnic tables, patio
lights, landscaping, flag poles, etc, etc, etc )

Say Uncle K Did I mention some of the ideas may be, well, "different"??
