The Hydrofarm MTMDU Seedling Heat Mat is re-engineered for better performance and greater durability. The new, stronger heating wire, and thicker multi-layer construction offers more uniform heating and the durability to withstand rugged greenhouse environments.

The bottom heat of the MTMDU seedling heat mat is a very important and effective way to increase germination and rooting. It will help you maximize your growing area by letting you daisy chain up to 4 of the MTMDA add-on units. These heavy duty modular commercial heat mats will provide uniform heat for hundreds of seedlings or cuttings.

doe's not uniformly heat ends of seed flat

Bought it for use in greenhouse to provide heat under standard seed flats 11 x 21 inch, Found it only provided heat over 17 inches.

other brands of COMMERCIAL MATS I have do heat the entire flat.Space waster, only works for three flats lengthwise not five crosswise as one would think for a 21 x 60 inch mat

Would I recommend this to a friend or family member? No
  • Simple to Set Up
  • Looks Good
  • Bad Design
