Gypsum Powder (200g) - Mushroom Substrate Amendment, Mycology Supplement

PURE GYPSUM POWDER ESSENTIAL SUBSTRATE AMENDMENT
High-quality 200g bag of pure Gypsum (Calcium Sulfate), a vital supplement for professional mycology used to optimize substrate performance. Gypsum provides essential calcium and sulfur while acting as a pH buffer to maintain the ideal environment for mycelium development.

TECHNICAL DETAILS
Our Gypsum is finely ground for maximum solubility and even distribution within your grain jars or bulk substrates. Its primary function is to prevent grain clumping, making it much easier to shake jars and ensuring faster colonization through better surface area contact. Packaged in a resealable airtight bag. Artisan quality produced in Italy.

QUICK GUIDE
Add Gypsum to your grain soak or mix it directly into your bulk substrate (CVG or straw). A standard ratio is approximately 2 to 5 percent of the total dry weight of the substrate. Sterilize your substrate as usual in an autoclave or pressure cooker at 15 PSI. Store the dry powder in a cool, moisture-free location.
