Growstone Gnat Nix! 9 Liter Chemical-free Control Bags, 4-pack |gpgc33cf

Package Includes: (4) 9 Liter Growstone Gnat Mix Bags ---------- This Growstone Gnat Nix! controls gnats at different points of their life cycle, therefore preventing adult emergence from hatching larvae and deterring females from laying eggs in the growing media. As a result, their life cycle is interrupted, and its population significantly reduced. Like all Growstone products, Gnat Nix! is made in the USA from 100% recycled glass.
