These bags work great, easy to keep sterile. I had no problems with my order and everything arrived right on time!

I have been buying from Midwest grow kits for awhile. Always good quality and super fast shipping

excellent quality, speedy shipping, great company!

I'm new to growing mushrooms and took a chance on buying 2 of the 2 bag packages. I inoculated all 4 bags and all are growing spores nicely. What made it nice is they were already sterile and ready to go I just needed to inject my spores!

These bags were my third order from Midwest Grow Kits. It's my first time without jars. The information in the instruction material gave me the confidence to try bulk growing and I don't regret it. Just like the jars, they work perfectly with zero contamination issues. The bags come with an injection port for easy streal inoculation. I ordered four bags a double order but two bags was enough for me to fill a large growing container. The medium again produces much fruit.
