Mushbag rye

The Mushbag contains sterilized rye grain that's suitable for the spawn production of most edible mushroom species. It's fitted with an air filter and rubber injection port that seals the bag hermetically after injection with liquid inoculant (a syringe containing spores or mycelium). Each mushbag contains over 1400 grams of rye, which usually gives a yield of one to one and a half kilos of fresh mushrooms.

Note: The Mushbag does not contain a syringe or spores. To get these, make a selection from our spore prints and syringes.

Usage

1) Clean the injection port

Desinfect your hands or wear sterile gloves. Use the supplied alcohol swab to desinfect the rubber injection port. Do not touch the port afterwards.

2) Flame the needle

Keep the needle of the syringe (not included) in a flame until it's red hot. Let it cool for 15 seconds.

3) Inject

Insert the needle through the rubber patch and inject the desired amount of liquid inoculant. If the flow is blocked, slowly pull the needle back a bit. Repeat steps 1-3 for every Mushbag.

4) Incubate

Carefully squeeze the bag to distribute the inoculant. Put it in a warm, dark place. Make sure the filter is separate from the back of the bag.

Once the mycelium starts growing, the bag will inflate a little. Shaking the bag now will speed up growth. The white filter is the most fragile part of the Mushbag, so be careful not to damage it when shaking.

Once all grain kernels are colonized by mycelium, the spawn is ready for use.

Important: If the Mushbag gets contaminated it cannot be saved. Never open a contaminated Mushbag.

5) Growing mushrooms

There are several ways in which the inoculated rye can be used to grow mushrooms. The easiest and safest method is to keep the rye in the bag, but cover it with a thin layer of vermiculite. To do this, carefully open the bag at the top (using sterile equipment), add the vermiculite, fold the top of the bag two times and close it with two paperclips.
