Who This Is For

  • You are adding a thermostat because your current setup relies on ambient room air that shifts too much at night to keep your starts consistent.
  • You are switching to digital control because guessing the temperature by touch in your propagation trays leads to uneven success rates.

What We Found

  • The sensor probe is actually worth the investment because it tracks the root zone temperature rather than the air temperature.
  • We tell growers to mount the display outside the humidity dome so you can check your status without constantly opening the lid.

What Users Say

  • Users who swapped out their old manual mats for this controller say they stopped losing cuttings to root rot from overheating.
  • Growers who struggled with inconsistent germination rates report that their batches now pop at the same time every week.

SunBlaster Digital Heat Sheet Controller

Are fluctuating ambient temperatures causing slow seed germination or poor rooting success rates in your propagation trays? Eliminate the guesswork and stabilize your root zone with the SunBlaster Digital Heat Sheet Controller. Engineered to provide constant optimum heat to your growing mediums, this digital thermostat ensures your fragile seedlings and cuttings develop robust root architectures without the risk of overheating or damping off.

The SunBlaster Digital Heat Sheet Controller provides high-accuracy temperature management for serious indoor growers. Featuring a straightforward user interface and a clear readout, this controller allows you to monitor conditions instantly. It comes complete with a highly resilient sensor probe that tracks conditions directly inside the soil or cell plug. Whether you are running a small mini greenhouse kit or managing a large scale commercial propagation rack, this reliable controller delivers the exact thermal stability required to maximize cloning success and expedite plant development.

FAQ

Can this controller be used with any brand of heating mat?+

Yes, it features a universal design. While engineered specifically for the SunBlaster Heat Sheet series, this digital controller is compatible with virtually all standard seedling heat mats on the market today.

Is the temperature sensor probe safe to use in wet soil?+

Absolutely. The controller includes a premium stainless steel temperature probe that is completely water-resistant, making it safe for continuous contact with wet growing mediums or hydroponic runoff.

How do I mount the temperature probe inside my tray?+

The system comes with a convenient suction cup mount attached to the probe cord. This allows you to secure the sensor firmly along the inner wall of your 1020 propagation tray or humidity dome at the exact root level.

Does the digital screen display temperatures in Celsius?+

Yes, the large bright display panel is completely customizable. You can toggle the temperature output metrics between standard Celsius or Fahrenheit depending on your preferred operational style.

How long is the sensor probe cable?+

The water-resistant sensor probe features a long 6-foot cord. This extended length gives you maximum flexibility to route the wire cleanly from high propagation shelves down to baseline power outlets.
