Stop fungus gnats and any other creepy crawlies from breeding inside growing media once and for all!

gnatnix! has undergone extensive trials and has been proven to be an effective tool against fungus gnats when used as a top dressing for your grow pots. Unlike other top-dressing products, gnatnix! targets fungus gnats throughout their entire 28-day life-cycle. 

The rough granular surface of gnatnix! creates a hostile environment for any insect that tries to move through it; preventing adult gnats from breeding in your grow media and trapping any pre-existing larvae beneath the surface.

gnatnix! remains effective whether dry or wet and can be used indoors in many grow room setups as well as outdoors in the garden or greenhouse.

How to use:

- Cover the entire top surface of your grow medium in your grow pot.

- We recommend using a layer about 2-3cm thick.

- If hand watering your pots it is recommended you have a thicker barrier of gnatnix!

- Wear a dust mask and eye protection when applying product, especially indoors.

- Take care not to inhale gnatnix! dust.

- Comes in a easy to apply 10L bag
