Description

【Faster Germination & Stronger Seedlings】Heat mats maintain an optimal root-zone temperature, speeding up germination and seedling growth, leading to stronger, healthier plants.

【 Consistent Temperature Control】They provide a steady, warm environment, essential for seed starting, clones, and tropical plants, even in colder climates. A stable temperature encourages strong root growth, which enhances nutrient absorption and overall plant health.

【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.

【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.
