Features: 1. PREMIUM MATERIAL: Constructed with multiple layers of flexible PVC encasing a heat-conducting film, the outer layer is sealed to protect the internal heating elements. It is wear-resistant, durable, and a must-have for starting seeds in the spring. 2. UNIFORM & STABLE HEATING: The heat-conducting wires are evenly distributed throughout the heating pad, ensuring that plant seeds are heated uniformly. This provides a constant temperature to improve the growth of vegetable, plant, herb, and flower seeds. 3. SAFE & EASY TO USE: The seed grow mat is designed to be waterproof, and its surface is easy to clean, allowing for safe scrubbing. Simply place the heating pad flat under the seedling starter trays, insert the plug into the socket, and turn on the power to start heating. 4. CONVENIENT STORAGE: This heating mat is light and compact, allowing you to roll it up and pack it in a bag when not in use. It won't take up much space, regardless of where it's stored. 5. VARIETY OF USES: Perfect for heating plant seeds or seedlings, greenhouses, grow boxes, home-brewing setups, and pet enclosures such as terrariums used for reptiles, rodents, and arachnids, especially in colder climates.
