10” x 20.75” Seedling Heat Mat with Digital Temperature Controller

Available at Holland Horticulture, this 10” x 20.75” seedling heat mat provides precise, gentle warmth to improve seed germination and early plant development. Designed for propagation trays and small grow setups, it helps create stable rooting conditions for faster and healthier growth.

Key Features

• Compact 10” x 20.75” size ideal for seed trays and propagators
• Digital controller with real-time temperature display
• Adjustable temperature range from 32–122°F (0–50°C)
• Far-infrared heating film for even heat distribution
• IP67-rated quad-layer PVC construction
• Flexible, durable and easy-to-clean surface

Precision Heating Control

The included digital thermostat allows accurate temperature adjustment to suit a wide range of plant species. The display shows current mat temperature in real time, removing guesswork and preventing overheating. The mat gently warms the rooting zone up to 20°F above ambient air temperature, encouraging faster germination and root development.

Innovative Far-Infrared Technology

Instead of traditional heating wires, the mat uses advanced far-infrared film to provide consistent warmth across the entire surface. This softer, evenly distributed heat protects delicate seeds from hot spots and scorching while improving propagation success.

Durable & Water-Resistant Design

Constructed from quad-layer PVC, the heating mat resists wear, moisture and damage. Its IP67 rating protects against water and dust ingress, while the sealed power cord connection helps prevent electrical issues. The flexible design allows the mat to be rolled for convenient storage when not in use.

Applications

Ideal for seed germination, cloning and propagation in grow rooms, terrariums and indoor gardening setups. For best results, pair with a humidity dome to maintain moisture levels. The mat can also be used for home brewing, fermentation and safely warming reptile enclosures.
