Masters mix mushroom dry substrate- 50% hardwood pellets, 50% soy hull pellets, and gypsum
They come mixed together; let us know if you want them separately by leaving a note during checkout.

The product needs to be sterilized and is excellent for wood-loving mushrooms except Turkey Tail and Shiitake, which require 80% sawdust and 20% bran substrate.

Your substrate includes:
  • 50%  clean, reputable hardwood pellets
  • 50% Soy hulls (High quality pressurized pellets)
  • A pinch of Gypsum (Calcium Sulfate) as a  mineral calcium supplement and reduce compaction
This premium mix with high nutrition gives you quick mushroom growth.
The soy hull contributes to quick and high yields due to its nutrient-rich content (Fiber and protein). Additionally, it encourages a larger-than-average first flush, allowing for a quick turnover.
