No matter what I order from Midwest, it always delivers as promised. Great products, great results!!! Highly recommended!

I love these guys, they always have excellent products, and as far as fast shipping, I placed a couple orders with a few different companies about a week prior to this order, and received my order from Midwest a few days BEFORE my other orders. One of my main suppiers.. 100% satisfaction every time. oh yeah, I almost forgot.. these guys customer service is excellent as well. well ran company for sure.

These work very well. Saves the time with duct taping poly fill on your mono tub. Highly recommended.

These disks are great! High quality O-ring is very sturdy! I ordered a Bulk Kit a month ago and it was before they had this product, I emailed support after seeing the change and they sent me these for free. They are great, easy to apply and really do provide the perfect amount of air exchange for a bulk grow! 5 star plus!

I’ve used theses for years and never a disappointment, they are reusable after soaking them in 3% peroxide which I’ve done and still works fine. Great to keep around
