Millet grain spawn bag

1.5kg millet grain spawn bag. Hydrated millet in an 8"x5"x20" bag with built in micropore filter for fresh air exchange and a self-healing injection port for easy inoculation with your favorite liquid culture! Autoclave sterilized and ready for use, just add about 5-10ml of liquid culture through the injection port and watch it colonize. Once colonized, 1.5kg of grain spawn can be used for fruiting multiple substrate bags.
