Amazon.com Review
This handy accessory to the Hydrofarm heating mats ensures that plants are kept at the optimum temperature for healthy, prolonged life. The thermostat is usable with all Hydrofarm mats and is accurate within 2 degrees F, plus or minus. The controllable temperature ranges from 68 to 95 degrees. Submerging the controller or the probe into the water is not recommended, and the thermostat will automatically shut off when the probe temperature reaches 110 degrees. With its suction-cup mounting device, the thermostat can also be used in a terrarium for air-temperature control and measurements. Gardeners who love their work to pay off quickly will be glad to know that using a thermostat and heating pad with the hydrogarden will assure faster sprouting. --Eli Huntington

Customer Reviews

works well but needs on/off switch
This works well at keeping the heating mat within a small temperature range. However, it would be much more convenient if it had an on/off switch. Currently, you have to unplug it to turn it off.

Didn't even last one season
I used this with the the smallest of heat mats of the same brand, and it stopped working within one season. I followed all instructions, and for the high price of this thermostat, I am very disappointed in its performance, or lack thereof. Too bad, because in theory it's a great idea.

Removes the guesswork!
This thermostat takes all of the guesswork out of achieving optimum growing temperatures for sure. The product works exactly as advertised. The only drawback is that mine came with a temperature probe that was a suction-cup type of device rather than a true probe. I have simply buried the suction cup into a small pot of soil that sits next to my plants (remember to keep the soil moist).

I have had a heat mat for 2 years now and have used it without a thermostat. The major problem with this arrangement is that I needed to put my heat mat on a cycled on/off timer throughout the day/night to sort of generally hit the temprature range I wanted. With the thermostat the heat is exactly the temperature I desire all day long. This has made a tremendous difference in my growing results. So far (this year) I have germinated my sweet bell peppers at 85 degrees F, and have grown the seedlings at 72 degrees F. What a difference! This is my best crop ever!
