See attached graphic of my "osmogro" houseplant watering system. I have an old pic of my african violet's second flowering which I'll send later. The osmogro hydrogel membrane is immediately below a pot with a completely flat-base forming a seal which prevents capillary and hydraulic flow of water, so flooding is avoided. The osmogro gel membrane sits on top of a fabric disc which facilitates water below the gel disc. The growing medium can initially seem quite wet but the system soon settles down to a happy (for the plant) but dynamic equilibrium.
