I've had nothing but success with every product I've ordered from these guys. If you follow thier directions everything works as promised. I've never had a contamination issue. I highly recommend midwest for all your mushroom growing needs. They literally make it foolproof. Thanks again midwest

I used to use box fans and filters. This kit does a better job, is easier to use.
