I was wondering if I could use lava rock as a substate... I have no intentions of growing anything in it, except maybe some moss on top of it. It's purely for aesthetics and making it super easy to clean/never having to change it. Here's my plan...
I'm gunna use a false bottom to take care of humidity. So... 2" pvc cuttings, and egg crate... Then I'm gunna use fiberglass window screen, an inch of charcoal to keep it fresh, another screen, and then a 1/2 inch of sand. Then I'm gunna take black pcv piping (6") and cut it just a wee tiny bit longer than the pot I'm using for the individual plants. (This is so I can remove pots w/o the rocks caving in and having to dig new holes for the pots, this will make life nice) I'll dig these into the sand a little to keep it secure. (Pretty much the whole purpose of the sand... maybe it'll have some sort of water filtering property?) And then I'll fill up to where the pots will be with lava rock. Then I'll fill it up with water.
I think it'll look nice, the dark rocks should contrast the plants nicely. And a little moss will make it look even prettier. Also... if I want a certain plant to sit higher, or stay drier, I can cut a longer piece of pvc and fill the bottom of it with sand, lava rock, or anything to take up space really.
Any thoughts, comments, and idea will be greatly appreciated.
Thanks guys.
