Is It Bad For Soil To Have Gnat Nix On Top For Too Long?

[Hellno187]

I haven't seen anything while researching to bolster the assumption that leaving stuff like Gnat Nix and diatomaceous earth is bad. However, I still kind of wonder if having a 1/4 to 1/2 inch of this stuff over my top soil is going to make it retain moisture? Any thoughts?

I use gnatgnix mixed with diatomaceous earth 1-2inches deep on all my pots for several(6-7)grows without any ill effect I can discern.

Hey Shroom, I kinda thought after researching that was the case but would rather hear it from someone with experience. Thanks.

Noob or not you have gone through 6-7 grows and not seen any ill effects, and that's the experience I was looking for.

gnats can't find a way in to my soil, ever.

I have detailed explination in my grow diary of how I use gnatgnix to stop gnats. I even reuse my gnatgnix.
Best of luck to you.

You recycle the Gnat Nix huh? That's exactly what I planned on doing because after all it's just ground glass. I figure if I shop vac it, and give it a rinse should be good to go lol.

Yes. I use a layer of weedblock landscape material between the gnix and the soil. Keeps them from mixing.

Really, weed block huh? What's weed block made of? Just curious I have no experience in landscape and never used the stuff myself.

Oh right that black tarp looking material, I know it's porous but does that effect the way nutrients are absorbed into soil when feeding?

No.
But it does block 95% of roots trying to grow through it.
