      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!

      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 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!

      Dope!

      Thanks for selling these!! I always stuff too much polyfil in the holes or not enough! Finally I dont have to go through the trial and error on how much to fill the holes with!! These things are great and really durable! Do you guys offer these in larger quantities?? I will send an email too. Peace!
