Seedling Heat Mat – Faster Germination & Root Growth
Boost germination rates and strengthen root growth with reliable bottom heat.
The Seedling Heat Mat creates the perfect root-zone environment for seed starting, cuttings, and propagation by warming the soil 10–20°F above ambient temperature. Ideal for greenhouses, grow tents, or indoor setups, this waterproof, easy-to-clean mat delivers consistent warmth that speeds germination and increases success rates.
Choose between a Master Unit (standalone power) or Add-On Unit (connect up to 4 mats via daisy-chain). You must have a Master Unit, to power an Add-on Unit.
For best results, pair with our Digital Heat Mat Temperature Controller for precise soil temperature management.
