Unicorn are great value, great quality and have a proven track record in the mushroom cultivation world. As the bags are plastic, once full, they can be sealed by heat sealers, this process can be unreliable and sometimes requires several attempts to get bags to seal. The filter patches are seemingly all the same both in physical dimensions and pore size which appear to be 0. U/H/D is the filter location, either up near the top, spread out or down near the bottom, and 2,4 or 6 is the number of strips.

You want to control the pressure of your autoclave, or other sterilizer to help you control the internal temperature as well. There are also special bags on the market for pasteurised substrates like these blakk brand log bags that have hundreds of pre-perforated holes. This helps those using liquid culture to create spawn bags with as little chance of contamination as possible. Controlling the airflow is a large part of what makes Unicorn Mushroom Grow Bags unique, and perfect for growing mushrooms. Our fungi, spawn, and mushroom growing bags offer unparalleled versatility, so you can meet your goals with assurance – and on your terms.Polypropylene is a thermoplastic that is often used in the food industry thanks to it’s high melting point of 160c and wide range of properties. 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. Polypropylene is a “thermoplastic” which won’t melt unless temperatures are sustained between 266 to 340 °F.

Transformativeness is a characteristic of such derivative works that makes them transcend, or place in a new light, the underlying works on which they are based. The bags loosely copy unicorn bags for sizing, though they don’t follow the same sizes all the time, sometimes the stated size is different from the actual size you receive. In computer- and Internet-related works, the transformative characteristic of the later work is often that it provides the public with a benefit not previously available to it, which would otherwise remain unavailable.Since every mushroom farm is unique we also carry many other sizes and even some specialty Unicorn Grow Bags. It would be rather annoying to have 1000 XLS bags or PP50/SEU4/V40-51 bags turn up only to realise they don’t fit your setup! 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. A new work based on an old one work is transformative if it uses the source work in completely new or unexpected ways.

As a mushroom grower you recognise that you will lose the odd bag to contamination or manufacturing imperfections, but when it becomes a regular occurrence of defects the failure accumulates over time. 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. 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. 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.To achieve this, the bags and filters have to be made from high temperature plastics to withstand sterilisation which is achieved at 121c. When you need high-quality bags for your business’s success, Unicorn Bags meets your specific needs.

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. Saco2 are more expensive but have a high quality and good pedigree being a sister company of mycelia.Our second most popular bag is the 3T which has a finer filter which is ideal for grain spawn use to prevent contamination.
