Microbe Life | Hydroponics FGX Fungus Gnat Exterminator 8oz

FGX controls fungus gnats where they do the damage: as larvae in the root zone. Its active microbe is BTi (Bacillus thuringiensis israelensis), a naturally occurring soil bacterium. Larvae that ingest it stop feeding and die, which breaks the life cycle. Microbe Life says it acts only on gnat larvae.

Mix it with water and apply as a soil drench. It's EPA registered for fungus gnat control and works in soil, potting mixes, coco and hydro systems including NFT, DWC, drip and aeroponics, alongside any nutrient program. Made in the USA. 8 oz.

Pairs with: Grow1 Sticky Card Traps Yellow 5" x 8" (10 Pack).
