Calcium Sulfate Dihydrate (CaS04)(commonly known as Gypsum) is a soft sulfate mineral that provides several minerals which encourage healthy mycelial growth, and prevents clumping in a Liquid Culture or Agar Petri dish solution.
Powdered Gypsum can be used as an ingredient in mushroom liquid cultures, or can be added to mushroom spawn medium during soaking of the medium to prevent clumping.
Add MYCO-PRO™ Powdered Gypsum to liquid cultures or Spawn medium (during soaking).
The amount of gypsum you should add will depend on the nutrient base of your liquid culture, or what type of spawn medium you are using. See our learn page for more information.
Tightly seal the container of Powdered Gypsum after use to prevent moisture absorption.
