Liquid Graphite Heating Mat (HM1)

4.91 stars, based on 34 reviews
This 21"x 11" under-tank style heating mat uses liquid graphite to evenly heat the surface with no hot spots! Traditional heating pads use wires, which can lead to uneven heating and hot spots. This powerful heater only uses 28 watts of electricity...

Great and mindless

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

The Liquid graphite heating Matt can keep great temperatures for either inoculation or fruiting. I’ve gotten up to 79 degrees in my 70 degree home. It can also be good for fruiting if you have a normally cooler home. Would definitely reccomend if you don’t want a base port heater or normal heater to break your bank!!!

Great product

Came right on time as always. No hot spots. Perfect size. It’s a little too hot to put directly under a tote if you don’t have anything in the bottom. I have my tote up on ½” wood pieces and a thick towel underneath my bags and jars. Works perfect. Way better than doubling up and having an aquarium heater.
