Sterilized CVG Substrate Bag | Mushroom Bulk Substrate
Take your mushroom cultivation to the next stage with our Sterilized CVG Substrate Bag. Perfectly hydrated and ready to use, this premium bulk substrate is designed to be mixed with your fully colonized grain spawn. No messy buckets, no boiling water, and no guesswork required.
What Is a Sterilized CVG Substrate Bag?
A CVG bulk substrate combines Coco Coir, Vermiculite, and Gypsum. It provides the ideal moisture retention, aeration, and physical structure for mushroom mycelium to thrive and produce massive fruiting bodies. Simply cut open the bag and mix this substrate evenly with your fully colonized grain spawn in a monotub or fruiting bag.
What's Included
- 1x 3lb Sterilized CVG Substrate Bag
- 2x 70% Isopropyl Alcohol Wipes
- Step-by-step mixing and fruiting guide
Compatible Mushroom Strains
CVG is a highly versatile bulk substrate preferred by a wide variety of mushroom strains. It is the industry standard for monotub grows because it provides exceptional yields while being naturally resistant to contamination compared to manure-based substrates.
Works perfectly in a 1:1 or 1:2 ratio (Grain to Substrate) with any fully colonized grain spawn.

Frequently Asked Questions
When to break and shake all in one bag?
When to break and shake all in one bag?
Break and shake your bag when it reaches around 30% colonization, taking two to four weeks. Just break up the grain without mixing it into the substrate. Once it hits 60 to 70% colonization, you should break it up again and thoroughly mix it with the whole bag.
Is there an easier way to grow mushrooms?
Is there an easier way to grow mushrooms?
No, using all in one grow bags are the easiest method to grow mushrooms. They were designed for beginners without any experience at all.
How to fruit all in one grow bag?
How to fruit all in one grow bag?
You can start fruiting directly in the bag once your block is fully colonized. Simply cut open the bag over the filter patch to introduce fresh air and trigger pinning. If it looks dry, mist the inside of the plastic bag every other day, never the substrate directly.
How to inoculate all in one grow bag?
How to inoculate all in one grow bag?
You inoculate the grain directly using a spore syringe or liquid culture. Use 2 to 3 ml for a small, 3 to 4 ml for medium, and 5 to 6 ml for large bag. Liquid cultures are always preferred, since raw spores are much more likely to develop a contamination.
How long to grow mushrooms in a bag?
How long to grow mushrooms in a bag?
It usually takes six to eight weeks to grow mushrooms in a bag. This timeline depends heavily on the strain and temperature, as well as your inoculation method. Using spores usually takes one to two weeks longer to colonize compared to using an isolated liquid culture

Free Replacement Policy
Our replacement policy covers bags that arrive contaminated or damaged during shipping. If this happens, we’ll send a new bag at no extra cost.
How it works: Please inspect your bag carefully as soon as it arrives. If you notice any contamination or damage, take clear photos and send it to us within 48 hours of delivery, before opening or inoculating the bag. You can reach us via email, our contact form, or Discord, whichever is easiest for you. Once we’ve confirmed the issue, we’ll ship your replacement.
What’s not covered: Bags after inoculation, for example with spores or liquid culture. We can only guarantee sterility up to the point of inoculation. Once you introduce your own genetics or open the bag, we have no control over your workspace or the quality of the genetics used, so contamination from that point on falls outside what we can be responsible for.
