That’s…pretty much it. They must be kept in non-porous pots and trays (glass or plastic), water TDS must be below 50 ppm and keep water in the tray constantly. They will even bloom with gorgeous little flowers. No fertilizer ever, just bugs.
I can’t emphasize enough a sunny spot. This window faces southwest and so it gets 8 hours of direct sun. This helps with growth and also makes the mucus shine which seems to attract the bugs.
nice! good to know! whatever you do, don’t treat the surface with hydrogen peroxide, or put a layer of fine gravel over the soil. that could diminish your fungus gnat harvest.
Yup, I’ve tried all the traditional gnat remedies but even if I eradicate them they always find a way back, so I decided to lean into it.
maybe you’ll drive them to population collapse due to exhausting the resources of their environment!
That’s always the dream, then I leave the screen door open one time and they find a way back in!
