FAQs

What is the ideal temperature for seed germination?+

Most seeds germinate best in a temperature range of 68-86°F (20-30°C). This thermostat allows you to precisely dial in the perfect temperature for your specific plant varieties, ensuring a higher success rate.

Can this thermostat be used with any brand of heat mat?+

Yes, the VIVOSUN thermostat is designed with universal compatibility and works with any standard seedling heat mat that uses a North American outlet, up to a maximum of 1000W.

How does the sensor probe improve accuracy?+

The sensor probe is placed directly into the soil or growing medium. This allows the thermostat to read the actual temperature at the root zone, rather than the ambient air temperature, and make precise adjustments to the heat mat. This ensures your seedlings' roots are kept at the optimal temperature for healthy development.

Is this thermostat safe for use in a humid grow tent?+

Absolutely. It is constructed from extra-fortified, water-resistant plastic to prevent rust and malfunction, making it perfectly safe for the high-humidity environment inside VIVOSUN grow tents and other propagation areas.

Can I control more than one heat mat with a single thermostat?+

You can control multiple heat mats as long as their combined wattage does not exceed the thermostat's 1000W maximum limit. Simply plug a power strip into the thermostat and connect your heat mats to the strip. However, for the most accurate reading, the sensor probe should be placed in one centrally located tray.

What other VIVOSUN equipment can improve my propagation setup?+

For a fully optimized setup, consider pairing this thermostat with a VIVOSUN heat mat combo kit and a humidity dome. For precise environment management, the Vivosun GrowHub E25 controller can automate your entire grow space. You can find more tips in our guide to controlling grow room temperature and humidity.
