Growstone Growstone Gnat Nix! 2L Bag
$10.36 $12.95
Gnat Nix! controls gnats at different points of their lifecycle, therefore preventing adult emergence from hatching larvae and deterring females from laying eggs in the growing media. As a result, their lifecycle is interrupted, and its population significantly reduced.
Like all Growstone products, Gnat Nix! is made in the USA from 100% recycled glass.
