For this purpose, you can use mushroom spore syringes. These syringes are fitted with spores that can be injected onto wooden incubator where they will grow and germinate. You have to calculate the exact number of mushroom spores and syringes you’ll need depending on the size of the population that you want to grow. Also, it’s important to keep track of the quality of the spores and make sure you don’t postpone their use for more than 30 days after making your purchase.
Although refrigerating a spore syringe can keep the spores alive much longer, it’s always best to use them fresh and ensure that the incubator and the environment will have the proper temperature and conditions, including being placed into a well-ventilated area.
