About this substrate

CVGM is our manure-enriched take on the classic bulk substrate: coco coir, vermiculite, gypsum and composted manure (about 10%), hydrated to field capacity and pasteurized for 6 hours. We pasteurize rather than fully sterilize because it preserves beneficial microorganisms that help your mycelium colonize. The added manure gives the mix a more nutrient-rich, biologically active profile for monotubs and larger grows.

Every batch is packed in Unicorn filter-patch grow bags, ready to use.

Sizes

  • 3 lb grow bag: mix your spawn right in the bag.
  • 10 lb monotub refill: bulk substrate for a standard monotub.

How to use it

  • 3 lb grow bag: add 1–2 parts colonized spawn to 3 parts substrate, mix it through the bag, seal it and incubate.
  • 10 lb monotub refill: mix with 3–4 lb of colonized grain spawn in your tub.
  • Work clean: sanitize your hands and surfaces before opening the bag.

Storage and shelf life

  • Keeps about 6 weeks at room temperature.
  • Can be frozen indefinitely. Thaw to room temperature before adding spawn.
