Gnat Nix will prevent nasty gnats and soil dwelling insects on your plants once and for all. Trial at Kansas State University have proven Growstone Gnat Nix! is an effective physical barrier against fungus gnats when used as a top dressing. Unlike other top dressings that are limited to one phase of control, Gnat Nix! controls gnats at different points in their lifecycle preventing adult emergence from hatching larvae and females from laying eggs in your growing media. The rough surface of Gnat Nix! is maintained whether dry or moist, or if used indoors or outdoors.

Coming Soon!

Fully cover the entire top of your growing media with approximately 1/2" - 3/4" thick layer of Growstone Gnat Nix! Make sure all your growing containers are fully covered at all times. Reapply as needed to keep this physical barrier intact. Irrigate with care to avoid disturbing the protective barrier of Gnat Nix!

When hand watering, apply a thicker layer of Gnat Nix! top dressing. For situations prone to heavy infestations, apply a thicker layer of Gnat Nix! top dressing and place a layer of Growstone Hydroponic Growth Medium on the bottom of your growing container at time of transplant to further reduce moist areas where female gnats can lay their eggs. Keep your growing area clean and free of moist debris. Expect great and long-lasting results. Any dust present from Growstone products should not be inhaled. If dust is present, always wear an approved face mask and eye protection.

Gnat nix

Great product, does exactly what it says it does. Thin layer on top of soil in my potted houseplants completely eliminates fungus gnats within a few days. Super easy to use.

Really helps prevent outbreaks by creating a barrier. Will definitely be keeping a bag or two around.

Stopped the fungus gnats

I had an extreme issue this time around with fungus gnats in my 7 gallon SIP. I believe the issue stemmed from using a Fox Farm "organic" soil as my wicking layer. I mean these guys were in full effect! I got the Growstone Gnat Fix and added the recommended amount to my top layer and the gnats ARE GONE....The only issue is that by adding this to the top of my SIPs is that we couldnt do any more top dressing so I feel this has effected the plants production in the fruiting stage. I do recommend this product for sure.
