Exceptional Results

The Mitchell Park Horticultural Conservatory Greenhouses integrate a number of complex systems, many of which were coordinated by the greenhouse contractor, Nexus.  Shading, temperature control, irrigation and bench warming systems in each of the seven greenhouses are monitored and coordinated by a central control system. All greenhouses have hydronic heating, cooling pads to regulate temperatures and a state-of-the-art watering and environmental control system.

One of the features of the greenhouses is the rainwater harvesting system. This system captures water from the roof, stores it and sanitizes it before irrigating the plants. It holds approximately 100,000 gallons of water to be reused for watering the plants.
