4-Pack Seedling Heat Mat 10" x 20.75" – Waterproof Hydroponic Heating Pad for Indoor Plants, Seed Starting and Greenhouse

Package & Size: Includes 4 seed heating mats, each measuring 10" x 20.75"—enough units for multiple trays, replacements, or sharing with family and friends for seed starting and cutting propagation in cold weather. Construction & Safety: Built from multi-layer flexible PVC coated with a thermal conductivity film. An outer seal protects the internal heating element, making the mat durable and waterproof and allowing you to safely wipe away dirt. Wear-resistant insulated wires increase safety, and the connection between the mat and the power cord is sturdy and reliable. Heating Performance: The hydroponic heating pad delivers consistent, uniform warmth across the surface to speed seed germination and encourage faster seedling growth. Even temperature distribution prevents damage caused by hot spots or excessive heat and reduces the chance of failed germination. Versatile Use: Designed for most plant seeds and seedlings that benefit from bottom heat during winter—suitable for indoor gardening, greenhouses, terrariums, and general home plant heating to maintain a warm environment. Storage & Convenience: Lightweight and compact, each mat rolls up easily for storage. Simply wrap the cord around the rolled pad and place it in a bag to save space when not in use.
