We have been making substrates and growing specialty mushrooms in large-scale commercial operations for over 35 years.  Now available to the public, our “always sterilized, never pasteurized” line of products includes a variety of blends specially prepared for “dung and wood-loving” mushrooms.

Over the last 30 years, we have helped many mushroom growers, novice and professional, scale their production. Growing mushrooms in poly bags has become the predominant method of mushroom cultivation at scale. The ease of use, aseptic nature of the production process, cost savings, and increased yield have all been factors in the adoption of grow bags. 

However, the two common themes our clients kept coming up with were bag integrity and lack of air exchange. We have solved these issues with a SubOne custom-designed mushroom cultivation bag.

We are introducing the industry’s thickest bag and a double-sided filter patch. 

Lack of fresh air exchange (FAE) and build-up of CO2 in the bags can stifle mycelial growth, prohibit pinning, and lead to reduced yields. Downward positive air pressure and good air movement are two of the key contributors to successful mushroom growth. The double-sided filter patch solves this issue. Additional air is circulated through the bag without increased risk of contamination. In side-by-side tests, where the bag is not opened until harvest, there are significantly increased yields due to better air exchange. The new design makes it so there is no need to orient the bags on your racks in any specific order, and air will get to either side effectively and further reduce labor costs.
