Highlights
- EFFICIENT & UNIFORM HEAT:Designed by advanced metal heating film technology, this innovative seedling heat mat maintains optimal temperatures around the root zone of your plants in 68-86°F (20-30°C)—the perfect environment for seed germination, enhancing germination rates significantly. Unlike traditional heating wires, the metal heating film provides a more stable and uniform heat distribution, achieving 99% electric heat conversion efficiency.
- DURABLE MATERIAL:Made of durable, heat-insulating PVC exterior and PET insulation layer, the heating mat is both wear-resistant and pressure-resistant, provides multiple layers of protection for long-last. Additionally, a constant temperature pad is placed at the bottom to prevent heat dissipation and enhance heating efficiency. IP67 rated waterproof surface is safe to scrub, makes the pad easy to clean.
- PRECISE TEMPERATURE MONITORING:Equipped with a external temperature sensor, this plant heating mat provides accurate monitoring of the actual temperature, which ensures precise temperature control for optimal plant care. Built-in overheating protection that automatically powers off the pad when the temperature is too high.
- SIMPLE HEATING SETUP:This thermostat has a 4-button interface for multiple function set. You can set a timer ranging from 0H to 24H according to your specific heating needs. The temperature setting range of heating pad is 41-113℉(5-45℃), digital display supports units in both Fahrenheit and Celsius.
- MULTIFUNCTION:This heating mat can not only use for seedling and plant germination, hydroponics, cloning or other indoor gardening but also for home brewing and fermenting beverages, and heating pet enclosures for reptiles, meeting your different daily needs
- Please Note that the controller's temperature reading comes from the probe. For safe use, insert the probe near the root zone of seeds/seedlings, at least two‑thirds deep, and secure it firmly. Do not place it in shallow soil or leave it exposed to air, otherwise, it will show a lower reading than actual soil temperature. This will cause the heating pad to run continuously and overheat, risking melting and fire. Always check probe placement before each use.
