Excellent product for dialing in ideal temp conditions

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

Great product fast shipping

I was a little skeptical at first on how this would preform. Boy was I wrong though! This heating pad exceeded my expectations, and has preformed perfectly!

This thing is great for getting a steady temperature, much better than a space heater. It's large, long enough to set four grow bags on it. And it's very flat.



There's no thermometer on it, so you have to get one separately. I got a combo hygrometer/thermometer at a local hardware store.



The dial doesn't have a baseline on it, so I inscribed one with an EXacto knife. I experimented to find the right setting. The highest started to go above 31C, so I backed it off until now it keeps my grow box at 27C. I waited 30 minutes between settings to allow temperatures to settle. Then I cut a mark in the controller base for a reference line.
