SunBlaster Digital Heat Sheet Controller The SunBlaster Digital Heat Sheet Controller is a precise digital thermostat designed to help growers manage root-zone temperature during germination, propagation and early plant development. Built for use with compatible SunBlaster Heat Sheets and propagation heat mats, this controller helps maintain consistent warmth for seedlings, cuttings, clones, herbs, vegetables and indoor garden starts. Stable root-zone temperature is one of the most important factors for successful seed germination and rooting. By allowing you to set and maintain your desired heat level, the SunBlaster Digital Heat Sheet Controller helps reduce temperature guesswork and creates a more controlled propagation environment. Why Choose SunBlaster Digital Heat Sheet Controller Digital temperature controller for heat sheets and heat mats Helps maintain consistent root-zone temperature Ideal for germination, seedlings, cuttings and clones Supports stronger root development during propagation Helps improve seed-starting and rooting success Easy plug-and-play setup Digital display for simple temperature control Wide temperature range from 20°C–42°C / 68°F–108°F Supports up to 1000W / 8.3A Suitable for indoor gardens, grow tents and greenhouses Great for use in cooler propagation areas Designed for accurate and reliable heat control Better Temperature Control for Propagation Heat sheets and heat mats provide gentle bottom heat, but a digital controller helps keep that heat at the right level. The SunBlaster Digital Heat Sheet Controller monitors the growing area and turns the connected heat sheet on or off as needed to help maintain your selected temperature. This is especially useful in basements, garages, greenhouses or grow rooms where ambient temperatures can fluctuate throughout the day and night. Ideal For Seed germination Seedling trays Cuttings and clones Propagation domes 1020 trays Root-zone warming Heat sheets and heat mats Indoor growing areas Greenhouses Grow tents Cool rooms and basements Herbs, vegetables and ornamental plants Home growers and commercial propagation setups Product Features Product Type: Digital heat sheet controller/heat mat thermostat Temperature Range: 20°C–42°C / 68°F–108°F Maximum Load: 1000W / 8.3A Input/Output: 120V / 60Hz Control Type: Digital temperature control Best Use: Propagation, germination, seedlings, cuttings and clones Compatibility: Designed for compatible SunBlaster Heat Sheets and propagation heat mats How to Use Plug your compatible heat sheet or heat mat into the SunBlaster Digital Heat Sheet Controller, then plug the controller into a suitable outlet. Place the temperature probe in the propagation area according to the manufacturer’s instructions, then set your desired temperature. The controller will help regulate the heat sheet by turning power on or off as needed to maintain a more consistent growing environment. Growing Tips Use with propagation trays and humidity domes for seed starting Keep root-zone temperatures stable for better germination Use a lower setting for sensitive seedlings Use gentle bottom heat for cuttings and clones Monitor plant response and adjust temperature as needed Avoid placing the temperature probe where it may give inaccurate readings Use in cooler rooms where extra root-zone warmth is needed Pair with SunBlaster grow lights for a complete propagation setup Important Use Notes Confirm compatibility with your heat sheet or heat mat before use Do not exceed the 1000W / 8.3A maximum load Keep electrical connections away from water and moisture Use only with properly grounded outlets Do not use damaged cords, mats or controllers Follow the manufacturer’s installation and safety instructions Monitor seedlings and cuttings regularly to avoid overheating Use in protected indoor or greenhouse environments only Digital Heat Control for Stronger Starts The SunBlaster Digital Heat Sheet Controller is an essential propagation accessory for growers who want better control over heat sheets and root-zone temperature. With digital temperature control, a wide operating range and easy plug-and-play use, it helps create a stable environment for germination, rooting, seedlings, cuttings and clones. Note: Always follow SunBlaster’s official compatibility, installation, electrical and safety instructions for proper use.
