Gro-Sure Heated Propagation Mat

A packet of seeds only ever gets one shot at germinating, and warmth is often the difference between a tray that stays stubbornly bare and one that's bursting with seedlings two weeks earlier than expected. This gentle heat mat slides under any combination of pots and trays, lifting the ambient temperature by 5-15°C to recreate the warmth of spring whatever the weather's doing outside. Water-resistant, cable-protected, and ready to plug in — the single upgrade that gets your whole growing season off to a head start.
