This is a 5lb bag of grain(900g) and oak sawdust (300g) fully hydrated, sterilized, and inoculated with first generation grain spawn.
We have found that this mix is perfect for inoculating substrate bags. This mix is packed full of inoculation pionts thanks to the added sawdust, and has all the nutrition of the grains to give it the vigor to colonize quickly.
Bags are inoculated and left to colonize for at least a week before shipping to ensure that you recieve viable and agressive spawn.
1-2 week processing time shipped with usps priority mail.
