【Latest Heating Film Technology】The 10” X20.75” seedling heat mat comes with the most advanced design, quickly heat the root area by 50-77°F (10-25°C) above the ambient air temperature within 2 minutes. Compared with the traditional heating wire, the innovative far-infrared film heating speed is faster, the energy consumption is lower, the soft heat distribution is more uniform, and does not consume the moisture in the air, which is much conducive to the germination and rooting of indoor gardening.
【Premium Material & Reliable Quality】The seedling heat mat has a five-layer structure, the outer layer is made of heavy-duty PVC material, and the intermediate radiant far-infrared heating film is wrapped in a double-layer insulating PET layer, which complies with MET and UL standards, and has multiple protections. It is not easy to be damaged, safer to use, sturdy and durable, with a service life of more than 30,000 hours.
【Water-resistant & Quick Cleaning】It is made of soft but strong material with smooth surface. The IP67 grade waterproof material can prevent splashing and spraying. It is convenient to clean the heating pad by washing and wiping, which helps to keep the equipment clean and normal operation, without safety hazards, and prolongs the service life.
【Promoting Seed Germination】 The warm environment provided by a plant heating mat can accelerate the process of seed germination, allowing seeds to develop into healthy seedlings more quickly.
【Facilitating Growth】 The warm environment created by a plant heating mat helps to elevate soil temperature, facilitating the growth of plant roots.
【Extending Growing Season】In cooler seasons or colder climates, a plant heating mat can extend the growing season, providing growers with more time for indoor cultivation.
【Easy Temperature Control】With a temperature controller, the temperature of the heating mat can be easily adjusted, providing precise control over the growing environment. The temperature setting range is 40°F-108°F (5°C-42°C). The temperature display range is 32°F-140°F(0°C-60°C).
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.
