Dr. Myc Gypsum

Standard gypsum is often granular and harder to dissolve, whereas this is a solution-grade powder designed to mix seamlessly into your substrate. It also includes added humic acid, biochar, and sucrose, which provide extra nutritional support that plain gypsum lacks.

Yes, it is formulated for versatile use in both bulk substrates and grain spawn. It is particularly helpful for difficult-to-fruit varieties that require a more stable pH and better moisture retention.

The inclusion of sucrose and specialized microbes helps stimulate mycelial growth, which typically results in faster colonization compared to using untreated grain spawn. While results can vary by species, it is engineered specifically to reduce wait times.

No, you shouldn't need to. The formula acts as a buffer, meaning it naturally helps regulate and stabilize the pH levels of your substrate, creating a more consistent environment for your mycelium.

Biochar improves the substrate's water-holding capacity, ensuring your mycelium stays hydrated, while humic acid aids in nutrient uptake. Together, they create a more hospitable environment that supports heavier, more robust yields.
