Grain Spawn

Pre-inoculated grain spawn. Save time on growth rates and eliminate contamination with our pre-inoculated spawn bags. 3lb of guaranteed clean grain spawn. Just break it up and mix it into your sub. Recommended ratio is 1lb of grain to 3lb of sub for good results.

Pre-order only right now as we integrate this into our usual routine. And if you guys want it, we'll make it a permanent addition! Please allow up to 2 weeks to prepare until this becomes a permanent option on the site and is no longer a pre-order item.
