This seedling heating pad adopts an innovative far-infrared heating film, which heats up faster and provides gentler and more uniform heat, significantly enhancing the speed and success rate of seed germination. The stepless knob can smoothly adjust the output temperature, eliminating the need for repeated switching throughout the process and preventing temperature fluctuations from interfering with the growth of seedlings. The IP67 grade four-layer PVC structure is flexible, fold-resistant, splash-proof and can be wiped clean easily. It has obtained dual electrical safety certifications from UL and MET, which are verifiable online, providing greater peace of mind when in use.
