Pros:
  • Overall heat coverage!
Cons:
  • Heating Position ping on the dial.
This heat mat is great for growing mushrooms. The heat is very soft and does not dry out my bulk grows like regular ones do. The heat is also very even. I am part of many online forums and people always tell me to heat the room and not the tub, well thats hard to do for some and can be very expensive. I have used this heat mat for almost a year now and the only reason I give it 4/5 stars is because I wish there was numbers to tell you what level of heat you were at, its nice because you can make tiny adjustments but if you accidentally turn the knob you have to start over. I guess not a big deal but I give it 90/100 in terms of my review. Oh and it only uses 27 watts of power which is like nothing! Less than a light bulb to run!!

Great heating mat
