Your seeds will only germinate if they are provided the right environment. Seeds need to be warmer than room temperature (75-80 degrees, to be exact) to sprout, and so you will see a much higher germination rate with a heat mat.

Spider Farmer’s Seedling Heat Mat warms the root area of seedling 50-77°F above the ambient air temperature, significantly improving the germination process and the success rate of seedlings and cuttings.

Description

【Latest Heating Film Technology】The 48″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).

    Unbelievable product! I used this mat to keep my outdoor home deck grow cage warm into the fall. It kept my pots of living soil activily growing into late November in Minnesota! It ran for 3 months straight with no issues in very inclement weather! I will use it in the Spring to get out early! See how I did it here: https://youtu.be/jDl8Yg1cUj8?si=cJSS_sKnGze1LRW3

    I bought this mat last year after my old wire loop mat failed. Wow. This has been a game changer. I struggled with vegetable germination in the past, and this mat has changed all that. “Don’t be fooled by cheap imitations” the old ads used to say. True here. I’ve turned several in my Gardening group onto this mat, and they’ve all loved it. The thermostat easy to use, and as advertised, consistent even heat throughout the surface. Couldn’t be happier.
