These bags are full of hydrated and sterilized millet bird seed, oats or a 50/50 mix of both. They are ready to be inoculated with your choice of Liquid Culture or Multispore syringe. 3 lb bags are best for multispore syringes due to slow germination of spores. Our 6 lb bag is perfect for liquid culture, agar inoculation and spawn expansion. 

Injection ports are included at no extra charge. Every grain bag is made to order. Please allow 24-48 hours before grain bag orders are shipped. 

What is a grain bag?
Grain bags are the first step in growing from either a multi-spore syringe or liquid culture. Once your grain bags are fully colonized, the next step is to mix them in with the substrate. Your substrate will consist of either wood sawdust, compost, manure or cocoa coir. We also sell substrate bags here under Growing Supplies.
