Description

The Vivosun Seedling Heat Mat Digital Thermostat Combo (48″ × 20.75″) is an extended-format propagation heating system designed for large-scale seed starting and professional seedling management. It combines a wide heating mat with a digital thermostat controller to maintain stable root-zone temperatures across multiple trays simultaneously.

This system delivers consistent, uniform warmth to support faster germination and healthier early growth, especially in controlled indoor environments. The integrated thermostat allows precise temperature regulation, while the sensor probe ensures accurate real-time monitoring. Built with durable, water-resistant materials and reinforced electrical connections, the mat is designed for long-term reliability in frequent-use horticultural setups.
