Hi y'all,

I'm curious as to all the ways you've maintained even moisture in the Semi-Hydro set up, and what you think of different methods so far, like placing Sphagnum moss on top, etc. I have a few types of plants that just don't appreciate that dry line, so I want to experiment to find the best way to keep the whole medium moist.

Also, has anyone use the water-holding crystals for the top of the pot? I just thought of that and was curious.
