Casing Spawn

PaclogoPAC is specially formulated substrate for use in mushroom casing soil to promote rapid growth and colonization of the casing layer. The advantages using PAC over homemade compost-based casing spawns include faster cropping time and more uniform colonization and pin set.

PAC is made using the same rigid standards as Amycel grain spawn and offers many benefits over traditional compost-based CAC’ing materials.  This includes the freedom from the risk of contamination by molds, virus, nematodes or mummy. PAC provides for consistent performance throughout the year, eliminating variations that can be introduced with variable raw materials.
