Our favourite grain spawn by far. Super quick growth and perfect results every time.

Hydrated lovingly then industrially autoclaved for 3 hours at 15psi until every living organism is completely dead... ready and waiting for inoculation. We only use genuine 4t Injection bags from unicorn as opposed to the cheaper and unreliable Chinese bags with stick on ports and we guarantee sterility every time.

Please note: Additional bits of chaff are expected in grain products, they don't affect the end products

Mushroom Grain Bags

Mushroom grain bags are specialized containers filled with sterilized grains, crucial for the intermediate phase of mushroom cultivation. To initiate the process, spores or mycelium introduced are injected into the bags through a port which automatically seals after the injection preventing any potential contaminants from entering.

Our mushroom grain bags also feature a 0.2-micron air filter, which allows your mycelium to breath whilst blocking airborne contaminants which could ruin you (and your mycelium's) day.

Additionally, if you have an agar plate with colonized mycelium, you can transfer it to the bag by carefully cutting the bag in a sterile environment, such as a laminar flow hood or still air box (SAB) before resealing the bag. 

Once fully colonized and contaminate free, break up the grains before mixing them with your substrate of choice.

The quantity of spawn used in relation to the substrate, known as the spawn-to-substrate ratio, and can vary between 10% and 50%, depending on factors like mycelium growth rate, substrate nutritional content, and the cultivation technique used. We want you growing great mushrooms first and every time and always recommend a more than less approach to adding spawn.

All our grain bags are sterilized in autoclaves and infused with gypsum and calcium carbonate, which help in separating the grains post-colonization and supply essential calcium for strong mushroom development.

For those curious about choosing the right grain bags, feel free to drop us an email, call or via our dedicated whatsapp help line anytime.
