Simply inject with the spores or liquid culture of your choice and wait. Once the grain is colonized mix together in the bag to grow out of the bag or dump into a tub.
1 bag is perfect for a small shoe box sized tub or combine more to fill a larger size tub. We recommend using within 3 weeks for best results.
Approximately 3 lbs each.
