Helpful details from the video
Unicorn Bags Filter Sizes
A Filter is the most common filter. It is .5 micron is common for grow bags for Oyster Mushrooms and other common varieties.
T Filer patch is .2 microns which is the smallest for air flow but had the least chance of contamination.
B Filter patch is a 5 micron size which is a much higher air flow. Thought to be used more for Oyster mushrooms since they grow and colonize so much faster than an A filter.
Bag Sizes
XLSA – 10 lb to 13 lb growing blocks which are easier to shake and deal with for some growers.
14A-great for 5lb – 7lbs growing block.
3T – ideal for great for your grain blocks for spawn.
Injection Port Bags
3-T Injection Port bags are great for your grain bags when you use liquid culture.
Unicorn Mushroom Grow Bags are used to grow mushrooms in an indoor environment. These bags have an area with a filter that lets air in but blocks outside contaminants. The best mushroom grow bags are made by a company called Unicorn. These are the bags we carry. Each bag meets high quality standards for air flow, filtration and durability. They are designed to be autoclavable which means both heat and pressure treated.
The bags are built to tight size standards. This allows the mushroom grower or farmer to create growing blocks and sterilized grain bags that are ready for inoculation with your ideal mushroom varieties. The term gusseted refers to the way these bags are intended to be folded (by design). 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. You would not want bulky blocks that were round or out of shape, they would be harder to store in your grow room, and much harder when trying to sterilize your spawn bags, or grow bags with your mushroom substrate.
Autoclavable
Autoclavable just means that the bag is able to withstand the high temperatures of an autoclave, sterilizer, or your favorite pressure cooker if you are just starting out. Make sure to keep the bags away from the metal sides of your equipment, or they will melt with the metal contact. Your autoclave will likely operate at 15PSI and 250 deg F. These bags are designed to withstand those stresses and hold up perfectly when properly used.
Polypropylene
Polypropylene is the material these Unicorn Mushroom Grow Bags are made out of. Polypropylene is a “thermoplastic” which won’t melt unless temperatures are sustained between 266 to 340 °F. This allows for the sterilization process below that heat range at 15PSI for extended periods. You want to control the pressure of your autoclave, or other sterilizer to help you control the internal temperature as well.
Unicorn Filter Patch
The Unicorn Mushroom Grow Bags are special not only because of the material, design, and quality. Each bag is special because of the Unicorn Filter Patch on the bag. Depending on your use you will choose a filter patch that is built into the bag to control air flow. More airflow on bags for one part of the process, and less air flow on others. Controlling the airflow is a large part of what makes Unicorn Mushroom Grow Bags unique, and perfect for growing mushrooms.

Our Unicorn Bags for Sale
Enhance your mushroom cultivation with our premium 100% Oak Pellets. Sourced naturally and free from added chemicals or oils, these pellets are specifically designed to serve as the ideal substrate for your mushrooms. Unlike heating pellets, which may contain unknown contaminants, our oak pellets ensure a safe and optimal growing medium for your mushrooms, nurtured with love and serious effort.
Our oak pellets are perfect for supplementation and are crafted from the same high-quality wood used in our popular Fast Fruiting Pellets, which are a blend of 50% Oak and 50% Soy Hull. Oak is the preferred wood for many mushroom varieties, including Oysters, Shiitake, Pioppini, Reishi, and Lion’s Mane, all of which thrive on oak sawdust.
You can enhance your oak pellets with additional nutrients or combine them with our soy hull pellets to create your own master mix. For growers who have access to some ingredients locally but lack oak hardwood, we’ve shipped as far as Hawaii to meet their needs. (For shipments outside the contiguous 48 states, please contact us.)
Available in 10 lb, 20 lb, 40 lb, and 80 lb sizes (and more), you can start with small orders by purchasing individual bags here or request a custom quote for bulk delivery. Ensure your mushrooms grow in the best medium available with our 100% Oak Pellets.
Which varieties grow best in oak sawdust?
Oysters, Shiitake, Pioppini, Reishi, and Lion’s Mane all respond well to oak sawdust. Purchasing in pellet form helps you measure the proper quantity for your substrate.
How much water should I add to my pellets?
That depends on the variety of mushroom and your growing conditions. A good place to start is at 60% water. Or 6lbs of water for every 4lbs of oak pellets. Remember, this will change based on the mushrooms you are growing and any supplementation you add to your substrate mix.
Why is oak preferred by many mushroom growers?
Oak is ideal, since it is very dense and offers plenty of nutrition for a longer, sustained fruiting period. Depending on your mushroom variety and strain, you may want to supplement your oak with brans, or with soy hulls for nutrition. We also offer the Fast Fruiting mix which is an ideal 50/50% mix of soy hulls and oak. We make our Fast Fruiting Mix at the pelletizing stage. This means less work for the farmer, and preservation of that ideal substrate mix.
Why do you sell the oak pellets separately?
Based on customer demand. In some areas of the United States getting good hardwood is difficult. So many of our customers prefer to order these top-quality pellets direct from Mushroom Media Online. By having pellets delivered they are able to keep up with their farms’ demands without spending time trying to find local sources.
What makes your pellets unique?
Our oak pellets are food grade pellets, that are naturally sourced. Not meaning that they are for consumption, but rather that with no added oils, or chemicals they offer the safest input for your mushroom production. With other pellets you may run the risk of chemicals or oils being on and in the pellets.
