    This 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 which can dry out your substrate. With infrared heating, it transfers heat through the solid objects and will not heat the air like traditional heat mats. This powerful heater only uses 28 watts of electricity but is equivalent to 200 Watts of heat. The adjustable dial allows for precise sustainable temperature control.

    Features:

    • High powered heating core equivalent to 200 watts of thermal heating
    • Size 21" X 11" (L X W)
    • Under tank design
    • No not spots
    • Fully adjustable heat settings from 70-86 degrees
    • 110-120V ONLY

    Cons:
    I was concerned about potential fire hazard or hot spots prior to this purchase, but fear not it works like a charm!! I have it sandwiched in between a towel and a pillow case so the bottom of the bags doesn't get to hot but with my jars I just used it straight. It keeps the temperature consistent especially if you couple it with the heat controller, it works flawlessly and is so much easier than the aquarium heater/water set up. So happy!!

    Works good

    • Lightweight
    • durable
    • good quality
    Cons:
    • Limited length of power cord
    Wide range of temperature settings. Pretty exact too with the adjustments. Just minor turns to the dial goes a long way. Do yourself a favor and get 2 when you order your grow kit.
