I have used this for an added layer of protection. Easy to use and great price for some extra piece of mind.

You can find these on amazon and elsewhere, but get it from here. Similar price, good quality, but most importantly midwest supplies a guide on how to use it in growing mushrooms! Midwest you guys are AWESOME!!!!

came quickly and worked great. no problems

It's been 4 weeks now and all is well. The kit showed up 1 day late but no fault of Midwest. It was like opening a present very excited and satisfied with the contents. I had problems with the heater going from one extreme to the other. Called Midwest and had a new heater lickity split! Midwest is a top notch company!

i love you guys...am referring you to my friends. You have provided amazing customer support...thank you!
