What is grain spawn: - Grain spawn is sterilized grains (rye, wheat, etc.) inoculated with live mycelium culture. In the spawn-production process, mycelium from a mushroom culture is placed onto steam-sterilized grain, and in time the mycelium completely grows through the grain. This grain/mycelium mixture is called spawn, and spawn is used to "seed" mushroom compost. - Grain spawn can be stored in a refrigerator for 3 months at 4C. - Mycelium is quite resistant. If you are not ready to inoculate right away, you can keep grain spawn in your refrigerator. - Be sure to use the spawn within that time so your mushrooms grow properly. The sooner you use the spawn, the more likely it is to grow mushrooms successfully. - Once the bag is opened, spawn should be used shortly. - Grain spawn must be mixed with bulk substrate before you can fruit it. - When using good quality spawn, substrate and under optimum conditions, one can easily harvest 600-900 grams of fresh mushroom from 1 kilo of straw. - The ideal temperature for a spawn run depends on the type of mushroom, but it is generally between 23 and 28 Celsius (73 and 82 Fahrenheit). - Grain spawn is generally considered to be better for inoculating smaller substrates or fruiting blocks.
