Overview

Seedfactor MET-certified Seedling Heat Mat delivers a dependable warm zone for root growth and early germination when used indoors. Built to endure routine use, it is waterproof and simple to wipe down after busy transplant days.

Designed for indoor settings, the mat sits under seed flats or small starter trays to help create a stable microclimate. While results vary, a consistent warm base can support steady germination and ready-to-transplant seedlings.

  • Four sizes fit different trays and setups: Mini, Small, Medium, and Large.
  • Waterproof construction and a multi-layer design withstand damp indoor environments.
  • Stronger heating wire and a 7.5 mm thick design provide more uniform heat distribution.
  • 105 F high-temperature resistant cylindrical SJTW power cord, 5.9 ft long, adds safety and flexibility.
