Liquid Graphite Heating Mat

4.91 stars, based on 56 reviews 56 review(s). | Write a review

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

Price was reduced while purchasing a kit

Cons:

None! Thermostat is great range.

No hot spots, just smooth even heat as viewed by FLIR1 cam. Came just the right size for 44liter grow tub.

This is a great heating mat. For me, the temperature can be dialed right in. I use this mat with the monotubs I purchased here and it fits perfectly. My house is rather chilly for most people and with using separate thermometer for my tubs (with the temperature probe inside the tub) I can dial in the temperature perfectly. Just make sure to follow the directions by placing a towel under the heating mat. I will be buying more of these. If your on the fence about getting one, just purchase it.
