Propagation Seedling Heat Mat 20" x 20"

Give your seeds the warm, stable environment they need to germinate quickly and uniformly with the medium-sized propagation heat mat. Designed for professional growers, hobby growers and indoor hydroponic setups, this durable heat mat increases rooting success by providing gentle, even bottom heat to seed trays, propagation cubes, and cuttings.

Compatible with standard 10" × 20" propagation trays, this heat mat delivers reliable temperature control that promotes stronger seedlings, improved root development, and higher germination rates. We recommend using with a heat mat thermostat to maintain stability in root zone temperature. 

Key Features:

• Promotes faster germination
  Gently warms the root zone to encourage quicker sprouting and more uniform seedling growth.

• Ideal root-zone temperature
  Raises rooting area temperature by approximately 10–20°F above ambient air temperature, creating the optimal environment for propagation success.

• Durable construction
  Waterproof, long-lasting design resists wear and tear in greenhouse, indoor grow room, or hydroponic use.

• Uniform heat distribution
  Evenly warms the entire tray surface to prevent cold spots and support consistent growth across all cells.

• Perfect fit for propagation trays
  Sized for standard 10" x 20" seedling trays used in hydroponic and soil-based systems.

• Energy-efficient performance
  Delivers stable heat output while using minimal power for ongoing propagation cycles.
