How to aerate edible mushroom bags? Practical tips to share
The first is the ventilation plug method, using wheat straw, cotton lint, sunflower stalks, corn cobs and the like as materials, tied at both ends of the mushroom bag to form ventilation plugs. Note that wheat straw and sunflower stalks should be cut into 3 cm long pieces; cotton lint should be folded into a cotton column with one flat end and one fuzzy end; corn cobs should be crushed to bean-sized pieces and wrapped into balls with newspaper. The size of the plug depends on the size of the mushroom bag: use a large plug for a large bag and a small plug for a small bag; it also depends on the incubation temperature. When the incubation temperature is low, the plug can be smaller; otherwise it should be larger.
The second is the ring method. You can buy flared rings, put them over the mushroom bag and then add cotton plugs. If you cannot buy flared rings, you can also make them yourself from plastic packing straps, and seal the opening with kraft paper and a rubber band. Note that when putting on the ring, it must fit firmly to prevent it from falling off.
The third is the ventilation hole method. Use a sewing machine needle to poke a row of holes at 6 cm from the bag opening, with a hole spacing of about 1 cm. When filling with material, simply sow the mushroom spawn at the poked holes. Do not poke too many holes, and note that you should not handle the mushroom bag while poking holes, otherwise the mushroom bag is prone to splitting during the filling process.
The fourth is the ventilation tunnel method. Use a thumb-thick tapered wooden stick to poke 3 holes 6 cm deep in a triangular arrangement at both ends of the filled material bag, then poke one hole horizontally at the middle sowing point, and place the mushroom bag in a disinfected room for incubation.
