Remember to carefully follow any additional instructions provided with your specific grow bag and mushroom species for the best results. Types of Mushroom Grow Bags Use a pair of scissors to cut a cross into the front of your bag. You will need to pull down the flaps where you cut and give the mycelium a good misting with water a couple of times per day.

Mushroom diseases: Diseases such as bacterial blotch or green mold can affect the health of your mushrooms. To prevent these diseases, maintain proper hygiene practices throughout the cultivation process. Remove any infected mushrooms promptly to prevent spreading.Once the fully colonized bulk substrate is completely covered with white mycelium, it's time to fruit the mushroom spawn and start the mushroom pinning stage. To trigger mushroom pinning and fruit your bag of fungi, you'll need to provide the right fruiting conditions, including light, air exchange (minimize CO2), and a relatively high humidity level. Simply cut or puncture the bag to increase the fresh air exchange (FAE), mist the bag to maintain a high humidity level, and place the bag in a bright location or use a mushroom grow light. Maintaining the right temperature and humidity is crucial for white mycelium growth and the formation of fruiting bodies.

When you’re learning how to grow mushrooms in a bag, you’ll realize that there are actually multiple stages of the mushroom growing process where bags can be used. As the mushrooms grow and mature, harvest them by gently twisting or cutting them off at the base. Harvesting times can vary depending on the species and environmental conditions. Continue harvesting as mushrooms reach their desired size, leaving some in the bag for further growth if desired.Diverse Range: Polypropylene is the material in which the bag is made out of. It is a “thermoplastic” which won’t melt unless temperatures are sustained between 266 to 340 °F. This makes it an ideal candidate for holding your grain or sawdust during sterilization. A pressure canner wouldn’t see those temperatures unless the pressure got to be over 25 PSI, which is way over the safe limit for home cultivators. Filter Patch You’ll know your oyster mushrooms are ready to harvest when the caps have opened up but not gone completely flat yet. To initiate the growth process, inoculate the bag with a spore syringe, liquid culture, or mycelium on agar. This step is crucial as it introduces the fungal mycelium into the bag, allowing it to colonize and eventually fruit.
