Gypsum Substrate Supplement
£2.99
Gypsum, a naturally occurring mineral composed of calcium sulfate, is a fantastic supplement for enhancing mushroom substrate. It is particularly effective for species that thrive in environments with a balanced pH and added calcium. Gypsum not only conditions the substrate by improving its texture and structure but also prevents clumping, ensuring even water distribution. By providing essential minerals, it fosters a conducive environment for robust mushroom growth.
