Review: Reliable and Sturdy Grow Bags! - My usual supplier was behind on restocking grow bags, so I recently decided to try something different - I saw the Sojourner grow bags and decided to give it a go for my gourmet mushroom growing, and I have to say, I'm beyond impressed with their performance. These bags have exceeded all my expectations and are now my go-to choice for mushroom cultivation. The first thing that caught my attention was the 6 mil thickness of the bags. It's thick enough to withstand use in my pressure cooker without tearing or leaking, yet still flexible enough to allow for easy handling and manipulation. I've used other bags in the past that simply couldn't handle the pressure and would give me a few fails, so I'm thrilled to have found a product that can. Another feature that I love about these bags is the 0.2-micron filter, which is perfect for my needs. It provides ample air exchange for my mushrooms to grow and thrive, while also keeping out unwanted contaminants. I've had zero issues with contamination since using these bags, which is a testament to their quality and effectiveness. Overall, I'm extremely pleased with the Sojourner grow bags, and I highly recommend them to anyone looking for a reliable and convenient way to grow gourmet mushrooms at home. These bags are made from high-quality materials, and they're incredibly easy to use. If you're tired of dealing with flimsy bags or bags that can't handle heat and pressure, but without breaking the bank, then give Sojourner grow bags a try. You won't be disappointed!

### ⭐⭐⭐⭐⭐ These are good quality bags
*by S***E on May 15, 2025*

Seems like a good product at a great price. Only issue is that they are shipped in plastic and the outside three bags had damage from shipping.

### ⭐⭐⭐⭐⭐ New thickness, turn your heat settings up to seal.
*by C***T on January 29, 2024*

I’ve be using these bags for a while now, I would have given 5 stars, but they recently changed the bag thickness, making it much more difficult to seal, and causing me to turn up the heat on my sealer almost to max heat. Happy to change my review, if they go back to their old thickness. I’d still recommend them, but the not sealing is an issue that wasn’t present before.- edit: I like the new thickness just took me a second to get it sorted!
