Propagation Seedling Heat Mat 60"x21"

The commercial seedling heat mat is a professional-grade propagation tool designed for nurseries, greenhouses, hydroponic farms and serious growers. Its extra-large surface and robust build deliver uniform, stable bottom heat across large trays — ideal for jump-starting germination and rooting for hundreds of seedlings or cuttings at once. We recommend using with a heat mat thermostat to maintain stability in root zone temperature. 

Key Features:

• Supersized Heating Surface (60" × 21")
  Covers full-size propagation benches or multiple seed-starting trays at once, making it ideal for commercial or large-scale growing.

• Strong 140W Output for Powerful, Uniform Heat
  Raises root-zone temperatures roughly 10–20 °F above ambient, promoting faster, more reliable germination and stronger root development.

• Rugged, Waterproof Build
  Built with durable, greenhouse-ready construction and sealed connectors to withstand moisture, frequent watering, and repeated use.

• Modular & Expandable System
  Easily daisy-chain up to 5 mats (1 master unit + 4 add-ons) to expand your propagation area.

• Better Propagation Success for Seeds & Cuttings
  Consistent bottom heat enhances root development, speeds up germination, and reduces stress on young plants resulting in more uniform transplants and higher yields.
