Biomed Solutions Mushroom Grow Bag Cap and Ring set offers a high-temperature resistant polypropylene sealing system with a breathable cotton filter, designed to replace traditional cotton plugs. Each 40mm cap and ring withstands up to 130℃ sterilization, ensuring contamination-free mushroom cultivation. The pack of 9 supports efficient, scalable indoor mushroom growing with easy-to-use, durable components.

## Description

The ring cap is widely used for sealing the mushroom bag in the process of edible fungus production, eliminating the traditional method of sealing with cotton plugs, easy to use and save labor, the seed cover is made of polypropylene material, which can be used under high temperature and pressure, and can withstand up to 130℃ high temperature

Review: You can reinforce the filter with another layer of porous tape + loosely placed aluminum foil (for breathing), but they do the job of keeping the contaminants out while providing safe and easy access for inoculation.
Review: The sleeves work really well. Some people have said they don't secure well at all but I don't think they are actually clicking the 2 pieces closed. They are very difficult to pry apart once you close them. Only downside is the cheap foam filter on top. I added some micropore tape on top of the filter and it works fine.

### ⭐⭐⭐ Review
*by S***H on 8 January 2023*

I wasn't really impressed with the quality of this product. I'm fairly new to mushroom cultivation so I was really excited to try these rings out but when I got them they were subpar in my opinion. They are super small and flimsy I'm not even sure what the filter is made out of and there were no instructions whatsoever. Save your money for some better options that are out there.
