Im planning on building a big 8 foot long L shaped shelf that slips right into my windowsills to facilitate all my plants, and Im still in the designing phase.
One idea I've been kicking around is the entire surface of the shelf is a huge pebble tray of river rocks with a plastic liner underneath it, maybe a couple inches deep, and just have the Nepenthes pots sitting directly on the top of the rocks. The idea being it would look really nice, and it'd give me a way to dispose of draining water from pots without having to suspend them over ugly water trays. Here is where my issues come into play though, if I was just to have all my pots sitting directly on this two or three inches deep bed of rocks, would the stagnant water sitting at the bottom be substantial enough to cause mold or fungus growth? Especially with the pots sitting directly on the pebbles? Would river rocks even be able to host mold? The amount of water coming from just watering plants is pretty minimal, and with regular watering trays there is never a whole lot of stagnant water in them for long.
If not, would actually filling it up with water like a normal pebble tray cause mold issues? A huge pebble tray like that would be a good and eye pleasing way to add humidity into my windowsill garden.
