Product Description

Our locally sourced organic Rye Grain has been hand selected. Prior to sterilisation our grain is carefully rinsed and soaked. We add a percentage of calcium sulphate to help balance the PH plus it plays a role in cell wall formation and mycelium development which contribute to healthy mycelial growth, strong fruiting bodies, and overall higher yields.

Mushrooms prefer a slightly acidic to neutral PH range so it also helps absorb and retain moisture by absorbing excess water and releasing it slowly as when needed. Complete with self-healing injection port and a filter to help with gas exchange, minimise contaminants and maintain moisture control.
