Metrolina Greenhouses Has Improved Heating Efficiency With Green Solutions

Sustainability started to become a keyword in the horticulture industry in the late 2000s, when growers began converting their heating systems to greener options to save on energy costs and reduce their impact on the environment. However, there haven’t been many operations that have invested in sustainable solutions on as large of a scale as Metrolina Greenhouses at its Huntersville, NC, headquarters. Six years later, the operation is still fully committed to its biomass heating system and everything it entails.     Metrolina first fired up its Vynke biomass system from Belgium in 2010. The four wood boilers cover 95% of the operation’s heating needs at its 201-acre main location in Huntersville, NC, and Metrolina still maintains its traditional heating systems for back up and to provide flexibility of resources. Wood chips are sourced locally, with the majority from local forestry activities like wood harvesting companies and developers. The other […]

Natural Ventilation And Fog Increase Cooling Efficiency

For greenhouse ventilation, two main methods are used — mechanical and natural. Mechanical ventilation includes fan-and-pad systems, which are a type of evaporative cooling system. Fan-and-pad systems cool air by passing outside air through a wet pad, lowering the temperature and humidifying the greenhouse. This type of system works best in hotter, drier climates, because the capacity for cooling with a fan-and-pad system is very limited in humid climates. University of Arizona associate professor Murat Kacira says a drawback of using a fan-and-pad type system is that it requires a lot of energy and water. “Water is needed for the pad system, and energy is needed to run the pump for water circulation over the pad as well as the energy to run the exhaust fans,” Kacira says. “Water is a precious resource with limited availability, especially in arid and semi-arid regions. “Another issue is there can be a temperature […]
