Greenhouse tests have shown that identical plants, cared for in exactly the same way, will grow up to three times faster when their roots are kept warm. In fact, if the air temperature is as low as 50 degrees, plants without root zone heating don’t grow at all while those that do have root zone heating continue to thrive and grow!

• Germinate seeds faster - ideal for starting seedlings!
• Grow plants up to 3 times faster!
• Keep soil temperature 15° to 20° above room temperature preventing root rot!
• Water resistant construction - spills just wipe off! Use with a thermostat.
