No it's called >>> Gnatnix crushed up glass 2 slice up the fungus gnats
That's cool. I've never heard of that. I've always just used a 1/2" of playground sand on top the soil to get rid of fungus gnats. That's what I thought it was. It's an old school method I learned from a rose gardener; the sand makes for an uninhabitable place for their eggs to hatch and grow.
