Description
The Vivosun Seedling Heat Mat (48″ × 20.75″, 2-Pack) is a large-format propagation heating solution designed to maintain consistent root-zone warmth for seed germination, cloning, and early plant development. By providing gentle, uniform bottom heat, it helps improve germination rates and supports stronger, more uniform seedlings across larger propagation trays or multiple setups.
Built with durable alloy Nikrothal heating wire and layered PET insulation, this heat mat delivers even heat distribution while minimizing hotspots and protecting delicate roots from overheating. Its flexible, water-resistant construction allows for easy cleaning and repeated seasonal use, making it suitable for both hobby growers and commercial propagation environments. When paired with humidity domes, it helps create an ideal microclimate for fast and healthy germination.
Designed for efficiency and scale, this 2-pack provides expanded coverage for multiple trays or larger grow spaces, making it ideal for greenhouses, indoor grow tents, and batch seed-starting operations. The mats are lightweight, rollable, and easy to store when not in use.
