Modern stadiums employ a combination of technologies to achieve this dual functionality:
Under-Soil Heating Systems: These systems circulate warm water or air through pipes beneath the turf, maintaining optimal root-zone temperatures to encourage grass growth and prevent snow accumulation. For instance, REHAU’s turf conditioning systems keep natural grass roots at optimal temperatures to extend the growing season.
LED Grow Lighting: Advanced LED grow lights provide the necessary light spectrum for photosynthesis, promoting healthy grass growth even in low-light conditions. Companies like SGL offer energy-efficient LED grow lighting units that allow grounds staff to adjust light and heat radiation according to the grass’s needs.
🏟️ Real-World Applications
Allianz Field (MLS) (Minnesota): Utilizes a combination of underground heating and grow lights to keep its playing surface warm, growing, and free of snow for most of the year.
Lower.com Field (Ohio): Employs similar technologies to ensure a playable surface during winter conditions.
