Why Buy From Grow Tents Depot
  • Dual Heating Mats: Designed to improve the success of seed starting and germination by accelerating the growth process. These mats emit steady heat making them an ideal solution for indoor seed germination and propagation. They can also be utilized for home brewing or fermenting beverages, and heating pet enclosures for reptiles.
  • Innovative Far-Infrared Film: Each mat is lined with a distinctive far-infrared film that warms up faster and distributes soft, even heat, hence safeguarding your seeds against scorching. The mats maintain a steady temperature range of 80-87°F (26-30°C), which is around 20°F above the ambient air temperature.
  • Adjustable Dial: Incorporated in the heating controller is an adjustable dial that facilitates set up of the desired heat output. This allows continuous temperature control over time without the need to repeatedly switch the mat on and off, which could lead to seed rot due to extreme temperature variations. Threshold levels include off, low, medium, and high.
  • Durable Quad-layer PVC: Crafted with IP-67 rated quad-layer PVC that’s flexible and resistant to wear and tear. It is easy to clean and comfortable to roll for storage.
  • Safety Certified: This heating mat comes with UL (E518635) and MET (E115128) certifications for electrical safety, which are verifiable through their respective online directories under AC Infinity Inc. The mat is also rated for fire resistance and ensures safe temperature regulation. Achieving an IP-67 rating, the mat and its 60-inch power cord are sealed to prevent water and dust infiltration, thus preventing potential electrical damage.
