Keep your seedlings safe and warm with a heat mat!

Seedling heat mat and packaging

Seedling heat mats and related controls warm propagation media for crops that germinate best above room temperature. Match mat dimensions and electrical specifications to the tray setup, and use a compatible thermostat when precise media temperature matters.

Follow the manufacturer's placement, moisture, outlet, and safety instructions; do not use damaged cords or exceed equipment ratings. Combine bottom heat with appropriate light and ventilation from Seed Starting Supplies.
