3lbs of fully colonized grain spawn with the variety of your choice on our organic white millet. These come in 4t unicorn bags with .2 micron filters.
As this spawn is fully colonized it should be used immediately or refrigerated up to 1 week in a clean environment.
Do not obstruct the filter patch, and leave the upper part of the bag unfolded and facing upward.
These cultures span a wide array of varieties and are for laboratory research, isolation and development.
