Sterilized Grain Spawn in Mushroom Grow Bag

Out Grows Sterilized Grain Spawn is for starting your gourmet mushroom spores. Simply inoculate with your favorite gourmet mushroom spores and allow to fully colonize at room temp for around ten days. Then you can break up your grain spawn and mix it a bulk substrate for huge bulk mushroom grows. Our multi grain spawn is made up of many different types of grains and fortified with minerals for vigorous growth. We chose small grains for a couple of reasons. First of all when used as spawn there are thousands more inoculation points then larger grain such as rye berries. Secondly we are able to obtain these grains from a local farmer. So we choose grain free of any additives and have found much higher success rates and colonization speeds then when using commercially bought grains. Out-Grow's all natural fortified grain spawn is guaranteed to have the correct moister content. One pound of grain spawn is equal to 1 quart in volume.
