Adding a Jump Start heat mat focuses warmth to your root area that is 10-20 degrees over the ambient temperature, as well as lets you control heat required for certain crops. All Jump Start Heat Mats are heat-bonded and UL-listed. Daisy-chain up to four mats together to bring coordinated warmth to the root zones of hundreds of seedlings and cuttings at once.
The Jump Start Heat Mat Thermostat™ is a digital temperature control device that allows gardeners to select and maintain optimum rooting temperatures for faster seedling or cutting growth. It is compatible with all Jump Start Heat Mats and most other seedling heat mats.
