About this substrate
CVG is the classic bulk substrate for mushroom growers: coco coir, vermiculite and gypsum, 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.
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.
