Sterilized Substrate & Grains

Sterilized Substrates & Grains

Many new mushroom farmers want to get pre sterilized substrates and grains. At Mushroom Media Online, we are working to provide these solutions. Our first offerings in this area are Paddy Poo™ and Goonie Grains™. The Paddy Poo™ is intended for varieties that thrive on compost substrate. Goonie Grains™ works with most mushroom varieties during the spawning phase. This is when you use the grains to grow your mushroom spawn on grains so that you have more healthy spawn material ready to inoculate your grow block.

Once inoculated your then let the blocks rest in your grow room to colonize the entire block and later start to pin with fresh mushrooms.
