Blue Myco's Premium Spawn/Grain Bags increase FAE (fresh air exchange) to promote faster colonization times and larger healthier fruits.  The larger hydroscopic patch with 0.22um filtration are strategically placed to promote air exchange.   Our extra-large gusseted bags measure 19" x 8" x 5" and use 3 mil PP material to significantly reduce micro-tears which greatly reduces the chance of contamination. 


When you start using Blue Myco's Spawn Bags the results are immediately noticable.  Watch your grain colonize faster and your fruits grow bigger!
