when I have used dunks they worked just fine, and what I did was put them in the water as I was adding the nutes etc, let them soften a bit, then crumble them up as much as possible. Even with doing that I will still have some odd sized larger bits here and there, I don’t get crazy about it. Then water as normal, and those gnats seems to stay away (at least more than doing nothing lol).
that stuff @Tonygreen is using is interesting though, just crushed recycled glass. I am sure it slices those gnats to pieces, just as diatomaceous earth and oyster shells do. It will be interesting to see how effective it is. I love gnat snuff porn lol.
