NOTICE (3/17/2020): For safety reasons due to the COVID-19 pandemic, access to our NHAES farms and greenhouses has been temporarily restricted to employees and essential research staff only. There will be no exceptions, as this is a UNH-wide decision made in order to protect our employees and our public. Thank you for understanding.

With more than 25,000 square feet of greenhouse space, the Macfarlane Research Greenhouses are dedicated to research and teaching associated with the NH Agricultural Experiment Station and College of Life Sciences and Agriculture.

The facility provides highly controlled environments for a diversity of research projects, including ornamental and food crop breeding, sustainable ornamental plant nutrition and development, aquaculture, biological pest control, bioremediation, and plant genetic diversity as well as substantial undergraduate and graduate instructional activities. The greenhouse environments are monitored and precisely regulated through a computer-based control system that creates a sustainable growing environment through the conservation of heat, electricity, water and fertilizer, and increased plant resistance to insect pests and diseases.

Integrated Pest Management (IPM) is a knowledge-based, holistic approach to managing greenhouse pest populations and diseases that considers all possible options, including environmental, economic and community concerns, before action is taken. Insect pests and diseases in our greenhouses are successfully managed through this preventive program of careful monitoring of pest populations and the introduction of appropriate biological controls.

In addition to on-campus research and teaching, the greenhouse facility is a significant resource for teaching and outreach to our local communities and horticultural professionals across the country. Our annual Spring Open House engage the general public in ongoing research and increase overall awareness of local, sustainable horticultural production here at the university and throughout the region. The conservatory greenhouse with its diverse plant collection and small fish pond is a welcome destination for many visitors, particularly in the depths of winter.

The Macfarlane Research Greenhouses are on campus just off Main Street near A-Lot and the UNH Visitor Center.
