These bags are not just containers but are specifically designed to support the growth and health of fungi by regulating gas exchange, humidity, and contamination levels. This article will guide you through understanding the differences in filter sizes—0.2, 0.5, and 5 microns—as well as the implications of various bag sizes.

We will first explain the most common mushroom growing bags by unicornbags.com


as well as the ones that you should use.

The other mushroom bags

These bags are less common but have other utilities.

  1. Gusseted Bags(A-B-T): These bags are known for their durability and stand-up design which makes them stable after filling. They are ideal for various types of mushroom cultivation and can handle the substrate weight without breaking.

  2. Pillow Bags (PE-PP): Preferred by many spawn producers, these bags are versatile and can be equipped with a variety of filter types. They are excellent for fast and efficient spawn production.

  3. Injector Port Bags (INJ): These bags are designed for use with liquid culture injections, making them a convenient choice for those looking to speed up the inoculation process while minimizing contamination risk.

  4. Degradable Bags (OXO): Available in both gusseted and pillow styles, these bags are made with environmentally friendly materials that degrade over time under certain conditions.

Unicorn Bags vs the others

The difference in mushroom cultivation bags between manufacturers in China and Unicorn Bags from the U.S. often centers around price and quality considerations. Typically, bags from China are less expensive, which can make them appealing for budget-conscious growers. However, this lower cost sometimes comes with compromises in quality, such as less durable materials or less effective filter performance, which might not be as consistent as those from more established brands.

On the other hand, Unicorn Bags, manufactured in the U.S., are generally regarded as more reliable. They are known for their quality control, use of FDA-approved materials, and innovative designs that cater specifically to the needs of mushroom cultivation. While these bags might come at a higher price point, they often provide better value for serious growers through enhanced durability and more consistent performance in maintaining the necessary environmental conditions for mushroom growth.

These differences mean that while bags from China might be suitable for casual or small-scale growers looking to minimize upfront costs, Unicorn Bags might be a better investment for commercial operations or those who prioritize long-term reliability and results in their cultivation projects.
