I’ve been doing these for years… they don’t work as intended for more than a year or two, and then become pretty unstable. Even the lady who created it went back to low-maintenance (as opposed to zero input) systems after a few years. Still with the dirt and all but not without water movement and stuff.

If it makes you feel any better, I totally get it.

I’ve thought many times how different the universe would be (would complex life on earth even work the same way???) if frozen water became more dense and sank like most frozen substances.
