This liquid graphite heating pad works great. It is very efficient and cost effective!

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.

I have only recently become a growing enthusiast... And was thrilled after my first flush! Then, things slowed down.... My 'growing conditions' are limited in area... And it occurred that I may not be getting enough warmth to the base...

I ordered this, and my 'tub' is suddenly flushing everywhere!

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!!

Fast shipping! Heating pad works as advertised. Can add a little heat or a ton of heat. Great for any grow.
