Our distributors and industry partners achieve success with a common starting point: Unicorn’s breathable grow bags. This allows the bags to be folded so they can lay flat for storage when full, and this bag design lends itself to multiple bags being placed in an autoclave or sterilizer. This helps those using liquid culture to create spawn bags with as little chance of contamination as possible.
They have 4 different filter types A, B, T and TV however, TV isn’t a very common filter type as it’s made with Tyvek. Polypropylene is a “thermoplastic” which won’t melt unless temperatures are sustained between 266 to 340 °F. When environmental conditions for your cultivation and growing processes require exceptional quality and performance, ensure you’ve selected mushroom cultivation bags that will exceed your expectations and help you thrive. I tried to find out the actual pore size through digging around but couldn’t find any information on it, though I’d imagine they are between 0. Depending on your use you will choose a filter patch that is built into the bag to control air flow.However, some people opt to use cable ties, food clips, rubber bands, string or even purpose made clamps to seal the bags. Unicorn are great value, great quality and have a proven track record in the mushroom cultivation world.
Some of the smaller bags like the 10T have an option of a pre-installed injection port, these are 4 times as expensive as the port-less bags so you’d be better of making your own filter patch by gluing them on, using silicone or just micropore tape. The smaller filter pore size is generally used for spawn while the larger is for substrate, however, these are interchangeable and often it comes down to the users preference and requirements.Once a substrate is inoculated, the bag will carry the mycelium through all the stages of growth before it’s time to fruit which is achieved by cutting the tops of the bags off, making an X in the side or removing from the bags all together. The 14A is the most popular grow bag for both its large size for a mushroom grow block, and its bag filter size for proper airflow when working with wood-based substrates. You want to control the pressure of your autoclave, or other sterilizer to help you control the internal temperature as well. Rubbish Impulse sealers seem to be plentiful, gussets folded in or laid flat mine seems to have a mind of it’s own and decides what bags it wants to seal, it was far from the cheapest sealer on the market !
Hobbyists and large-scale companies alike require high-quality, durable, contaminant-free mushroom cultivation bags for maximum success at a low cost. They’ve also developed them in such a way that the filters don’t transpose much moisture so the grain or substrate pressing up to the filter doesn’t dry out.
Saco2 are more expensive but have a high quality and good pedigree being a sister company of mycelia. When we talk about mushroom bags, we’re generally talking about autoclavable, polypropylene, bottom gusseted filter bags. Whether you’re just getting started with mushroom cultivation bags and growing mushrooms, or you’re looking to successfully position yourself as a distributor or large agricultural business, you can rely on Unicorn Bags as your starting point for mushroom, spawn, and entomopathogenic (biocontrol) fungi cultivation.
