Other than minimal maintenance and misting they are probably the easiest mushrooms to propagate. They grow naturally in wood, but you also can raise oyster mushrooms successfully in other growing media, such as sawdust, wood chips or straw. Most grow under a temperature range of 55 to 65 degrees F.
Oyster mushrooms are great for someone who has never grown mushrooms before, your chances of success and waiting time from planting to harvest is much better than than with most other mushrooms.
Some varieties are mere specks, and some are as big as your head. A kit is the best starting point. Check with your supplier to determine what varieties are best for your particular needs. Most kits contain a small inoculated log or a plastic bag with a lot of holes, containing sterilized, inoculated growth media such as sawdust.
Should you obtain spores [spawn] not from a kit , than any grow media you decide to use needs to be sterilized. This is done by microwaving , boiling or steaming . Don't do this if you purchased a kit as the sterilizing process will kill the spawn.
