Review on Wathai Playtations Receivers Computers Electronics by Original Mansel

I use this product to grow shiitake mushrooms and lion's mane in a monotube. One serves to ensure a lot of air exchange and the other I use to regulate the temperature. The ability to control fan speed with a speed controller is a blessing. This has allowed me to achieve the exact air exchange I need to get a big harvest every time I start flushing the grow blocks. I will be using the same fans for my microgreen growing racks on each shelf as well. I highly recommend this product. So far no problems.
