About This

  • Essential for mushroom growth: Gypsum powder is an essential ingredient in creating the ideal substrate for mushroom cultivation for several reasons such as pH adjustment, calcium supplementation, water retention, and allow for better oxygen circulation and mycelium development.
  • Promotes healthy growth: Our premium-grade gypsum powder provides the necessary pH balance and essential nutrients (calcium and sulfur) for mushrooms to thrive.
  • Enhances water retention: Gypsum has a unique ability to absorb and retain water, which can help to regulate moisture levels in the substrate.
  • Reduces clumping: Adding gypsum to the substrate can help to reduce clumping and improve the overall texture of the substrate, which is important for air circulation.
  • Solution Grade Gypsum: High-purity form of gypsum is an ideal soil amendment that improves soil structure, reduce soil erosion, and supply essential nutrients such as calcium and sulfur to plants and mushrooms. 97% calcium sulfate dihydrate.
