## Overview

Biomed Solutions Mushroom Grow Bag Cap and Ring set features a 40mm polypropylene cap and ring with a cotton filter cover, designed for easy sealing of mushroom cultivation bags. Built to withstand sterilization at 130℃, this pack of 9 ensures contamination-free, efficient mushroom growth with a modern alternative to traditional cotton plugs.

## 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: They're good - 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: Didn’t fit my bags - May be my fault but I couldn’t get the cap on the collar. It was like the bag was interfering with it snapping in place.

## Customer Reviews

### ⭐⭐⭐⭐⭐ They're good
*by S***F on December 18, 2025*

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.

### ⭐⭐⭐ Didn’t fit my bags
*by S***Y on April 20, 2026*

May be my fault but I couldn’t get the cap on the collar. It was like the bag was interfering with it snapping in place.

### ⭐⭐⭐⭐⭐ Auto clave compatible
*by T***D on June 25, 2023*

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.
