Hydrofarm's Add-on Heat Mat will provide uniform heat for hundreds of seedlings or cuttings.
Bottom heat is one of the most important and effective ways to improve germination and rooting.
This new, heavy-duty heat mat helps maximize the growing area by allowing the daisy chaining of up to 4 of these add-on units to the Hydrofarm Commercial Heat Mat.
• Supersized mats: 60" x 21"
• Rugged and durable with waterproof connectors
• Daisy chain up to 5 units (4 of these add-on units plus the Commercial Mat)
