🧪 5-Pound Sterilized CVG Substrate Bag — Ultra-Clean Fuel for Explosive Growth

When you want nothing but sterile precision, our 5-pound sterilized CVG substrate bag delivers. Each bag contains a perfectly balanced blend of coir, vermiculite, and gypsum (CVG) — fully hydrated, sterilized in a cleanroom environment, and sealed tight for contamination-free performance.

This substrate is ready to mix directly with colonized grain spawn, or to use in sterile bulk setups like monotubs and bag fruiting. No pasteurizing, no prepping, no guessing — just open, mix, and watch your mycelium take off.

Why growers love it:

5 lb of pre-hydrated sterilized CVG substrate

Sterile-sealed for contamination-free use

Ideal for monotubs, bag grows, or grain spawn expansion

Perfect moisture and texture for rapid colonization

Produced in a professional cleanroom for consistent results

Sterile, simple, and stupid-effective. Just add spawn and let your mycelium feast.
