Unsere gebrauchsfertige CVG-Mischung beginnt mit unserem eigenen RHP-zertifizierten MycoCoco als Basis (die erste Kokosfasermischung, die speziell auf ihre Eigenschaften für die Pilzzucht hin erforscht und ausgewählt wurde). Dann fügen wir asbestfreies Vermiculit in Gartenbauqualität aus den USA hinzu und vervollständigen das Dreiergespann mit OMRI-zugelassenem Gips. Diese Komponenten haben eine geringe Bakterienbelastung und einen niedrigen Stickstoffgehalt, wodurch sie weniger anfällig für Kontaminationen und ideal für Anbauanfänger sind. Das Ergebnis ist ein perfekt ausgewogenes Substrat, in dem Pilzbrut gedeihen und fruchten kann.

Feuchtigkeitsgehalt: Jede Packung ist optimal hydriert für schnelle Kolonisierungszeiten und beste Erträge.

Verhältnis von Brut zu Substrat:

Wir empfehlen, 1 Beutel besiedelter Getreidebrut mit 2-4 Beuteln CVG zu mischen. (Höhere Inokulationsraten können Ihren Erfolg verbessern.)

How to Use

Spawn to bulk ratio

We recommended mixing 1 colonized grain spawn bag with 2-3 bags of sterile substrate. (Higher inoculation rates may improve your success.)

Best Practices

We recommend clean hands, latex or nitrile gloves, and sterile technique when using sterile substrate to reduce the introduction of contaminants.

Be sure to mix colonized grain spawn thoroughly into your substrate.

It is best practice to wait a minimum of 1 week after arrival before using sterile substrates to ensure they were not compromised during transit. Rest assured that your purchase is 100% guaranteed. If your substrate was compromised, we will replace it.

Storage

Sterile substrates should be stored at room temperature out of direct sunlight. No refrigeration is necessary. They can also be stored for several months before use.

Made Right, Guaranteed

Sterilized in a commercial-grade autoclave for consistent results
Multiple bags from every batch tested in our state-of-the-art lab
Verified using biological indicators and temperature sensors
Backed by our 100% Guarantee — if it’s not sterile, we’ll make it right

Sterile Substrate FAQs

Choose Boomr Bag for massive flushes of dung-loving species, CVG for versatile bulk grows and great moisture retention (great for beginners), and Wood-Lovr for wood-loving species like oysters, lion’s mane, and reishi. Each is optimized for the best yield and growth rate in its category.

Keep bags at room temperature and out of direct sunlight. Substrates can be stored for several months, and grain bags should be used within a few weeks for best results.

We sterilize our products in commercial autoclaves and test every single batch for bacterial growth so you know the product is sterile when you receive it. And if the bag is compromised in any way during shipping, our 100% guarantee means we'll make it right

While you can grow directly in the bag, the best way to grow with bulk substrate is to to use a monotub.

A general rule is 1 colonized grain bag for every 2–3 substrate bags. Higher spawn ratios often speed up colonization and reduce the risk of contamination.

Grain bags are for colonizing mycelium, while sterile substrates (like Boomr Bag, CVG, or Wood-Lovr) are for fruiting mushrooms. You’ll inoculate the grain bag first, then mix the fully colonized grain with your chosen substrate to begin fruiting.

Incredible product. Access to pre-sterilized soil is great for beginners. My only gripe is storage in plastic, but I understand how it may not be possible for such a large company to switch.

Worked wonderfully for my dung loving species

During my first dung species grow, I was unsure if I should use dung based substrate or go with CVG since I was growing indoors and wanted to keep smell down. After consulting with North Spores wonderful support staff, I was confident I would get good grow and yield using CVG instead of dung. Was perfect advice, got very aggressive colonization (under a week) and three flushes from this. Amazing product and my go-to now.
