Grain spawn bags 1.5Kg


1 in stock (can be backordered)

The special filter bags are half-full with hydrated and sterilized organic rye/ wheat berries, ready to be inoculated with your culture of choice from our liquid cultures.

The 1.5kg grain filter bag is the best for liquid culture inoculation, agar inoculation or grain-to-grain expansion.

We don’t use injection ports with our grain spawn bags, but simply wipe spot with 70+% alcohol swab, inject through the plastic near top of the bag and patch with a piece of micropore tape.

Grain bags are the first step in growing from either a multi-spore syringe or liquid culture. Once your grain bags are fully colonized, the next step is to mix them in with the substrate.

Your substrate will consist of either supplemented wood sawdust, MasterMix or compost. We also sell substrate bags in the Mushroom Growing Supplies category.

Each grain bag is made on pre-order. Please allow us 24-48 hours before grain bag orders are shipped.
