By far the best customer service and shipping time I’ve seen in a while...They will respond to emails right away and have the item shipped out the next day. Also, Injected my bags with spores four days ago and when it’s time I will be definitely be buying my substrate from these guys. 100% satisfied so far!

Great for monos only can find them here

This was the 3rd time ordering from Midwest and it's all been excellent.Love these disks! So easy

Long time customer! I bought these last year when you guys had a different version, I love the new material and now I can re-use!! These are worth their weight in gold! I was getting mold in my bulk grows and couldnt figure out why, go figure I was putting too much polyfil in the holes. I swapped out to these and never had a single issue since!

Once again Midwest comes through with another quality product in the size I needed that I couldn't find anywhere else. These filter discs are exactly what I needed for my custom shoe boxes. Peal them off, stick them on. It doesn't get any simpler.
