Brown Treasure Willy's Blend Substrate

Willy's Blend is specifically formulated for manure-loving mushroom varieties. It provides the ideal nutrient profile for species that thrive in enriched, organic environments.

No, this blend arrives ready-to-use. It has already been processed and aged, so you can mix it directly with your colonized grain spawn without any additional preparation.

While ratios can vary based on your specific mushroom species, a common starting point is a 1:1 or 1:2 ratio of grain spawn to substrate. We recommend following the specific cultivation guidelines for the variety you are growing.

Aging the manure for two years ensures the material is fully broken down and stabilized. This process creates a more consistent nutrient density and reduces the risk of contamination, which helps support faster colonization and higher yields.

Yes, the substrate is pH-balanced during production to provide a stable environment for mycelium growth. You do not need to add any buffers or adjust the pH yourself.

It is best to use the entire bag once opened to maintain the integrity of the substrate. If you must store it, keep it in a cool, dry, and dark place, but be aware that exposure to air can compromise the ready-to-use state.
