A sterilized local Texas hardwood blend of at least 4 of the best hardwoods used in mushroom cultivation throughout the world. These woods are specially handpicked from freshly downed logs locally and then run through a sawdust grinder. This is not store bought or bagged wood or partially composted wood. Trees were not cut down for bagging purposes, all wood comes from FRESH local Texas tree trimmings which include the best hardwoods in the world for any woodlover's project. Any of the gourmet and medicinal mushrooms that grow on hardwood will grow on this substrate. Wood blend already contains all "food" (nutrient) needed for healthy mycelium growth for any woodling mushroom species.
Bag contains 4lbs of sterilized wood
Bag has 0.2 micron filter

*Be careful with 5 micron filter bags (that seem economically priced) as they are extremely prone to contamination and is the most commonly sold online because they are easy to make. A 5 micron filter bag can be sealed prior to sterilization eliminating over 60% of the work and 100% of the sterile procedure work in exchange for a very poor filter that in our experience contaminates extremely frequently since mold spores are between 1-3 microns, so why would you use a 5 micron filter? ...We don't. We've invested everything in our laboratory to be able to provide the best filter bag available in the world which is autoclaved and sealed and packed AFTER sterilization in a Certified ISO 3 (Class 1) Cleanroom using extremely sterile procedures infront of 0.1 micron ULPA HEPA Flow Benches. The extremely small pore size of the bags we use of 0.2 microns explodes in the autoclave if sealed prior to sterilization, and the only way to be able to use it is to autoclave with the bags unsealed and the autoclave must lead to a cleanroom and directly to a sterile air flow bench, to be sealed and bagged. The performance of our bags and long term results speak for themselves.
