Why Buy From Grow Tents Depot
  • Latest Heating Film Technology: The 10” X20.75” seedling heat mat uses state-of-the-art design, rapidly warming the root area by 50-77°F above the ambient air temperature within 2 minutes. Unlike the traditional heating wire, the innovative far-infrared film heats faster, uses less energy, provides a softer, even heat distribution, and does not consume the moisture in the air, greatly encouraging the germination and rooting of indoor gardening.
  • Premium Material & Reliable Quality: The seedling heat mat has a five-layer structure with the outer layer made of durable PVC material, and a double-layer insulating PET layer wraps the intermediate radiant far-infrared heating film. Adhering to MET and UL standards, and equipped with multiple protections, it's robust, safe to use, and durable having a service life of more than 30,000 hours.
  • Water-Resistant & Quick Cleaning: Constructed of soft yet sturdy material with a smooth surface, the IP67 grade waterproof material can withstand splashes and sprays. The simple to clean heating pad maintains cleanliness and ensures normal operation, without safety hazards, extending its service life.
  • Simple Heating Setting: This plug-and-play thermostat controller is designed to regulate the temperature of the heat mat, providing plants with a stable and controllable heat source during the budding stage. The adjustable thermostat allows adjustments according to the plant conditions at any time to speed up the plant growth or cutting. The temperature setting range is 40°F-108°F, with a display range of 32°F-140°F.
  • Wide Application: Ideal for warming plant seeds or seedlings in cold conditions. Used with the controller, it can provide a temperature-controlled environment for better germination and plant growth. Even during the cold winter, indoor gardening can begin at any time. Additionally, this seedling heat mat kit can also help maintain a controlled environment for aquariums and other domestic animals.

    Having noted the low overall ratings of other heat mats compared with Spider Farmer, I gave this unit a try. I am using the paper towel method to germinate hot peppers. The controller was set to 82F, and the sensor placed between zip loc bags containing the seeds. Adjacent to the sensor was a hand-calibrated reference thermometer previously used to do quality assurance monitoring in a medical lab. There is a slight delay in the sensor readings, but at the top and bottom of the temperature range the Spider Farmer was off by less than one half of one degree compared to the reference. That is pretty hard to beat for a product in this price range! A second lab thermometer displayed a full degree below the reference. Yes, I am happy and would suggest this product to anyone using seedling heat pads. It also worked with an older heat pad purchased years ago from a seed company.
