Elm oyster mushrooms are great for beginners as they are reliable producers and tend to grow large flushes. They are firm and durable and have good tolerance for different temperature and humidity levels.  They are also one of the easiest blocks to get subsequent fruitings if kept in the right conditions.


Fruiting Blocks typically ship within 3-5 days, but can take up to 10 days before shipping.  If you do not use the block immediately, it can be stored in the refrigerator for several weeks before use.


You can find the complete instructions for your fruiting block here.
