Isaac's Greenhouse

Greenhouse Wide

Princeton Day School maintains a 600 square foot climate-controlled greenhouse in a courtyard across from the Upper School science labs.  The greenhouse supports all three divisions and is home to a large rotating collection of plants for research and teaching.


  • Diverse plant collection representing many regions of the world

  • Hydroponic grow tower with lighting and timers

  • 8’ x 2’ grow bench with lighting run by timers

  • Small classroom area

  • Stainless potting tables and rolling material bins

  • WIFI, Apple TV, and large monitor

  • 80 gallon rain barrel for water sensitive plants 

  • Rolling growing benches

  • Adjacent landscaped courtyard for additional plant display 

  • Climate controlled

Use of the greenhouse

PDS faculty use the greenhouse for study and research in evolution, ecology, sustainability, biology, plant neurobiology, language, fine arts, mathematics, and so much more. Classes visit the greenhouse and plant material is brought into other classrooms. Studying the mutualistic relationship between plants and animals allows the students to better understand their own role in a much larger ecosystem. All plants employ a diverse set of strategies for survival. The PDS greenhouse collection can give students some insight into understanding the impacts of climate change on plant survival. In early spring our Garden Coordinator raises over 600 seedlings for the famous PDS garden and wildly popular seedling sale.

Isaac's Greenhouse and Penny Wallace '69 Courtyard Create Interdisciplinary Space

Princeton Day School formally dedicated Isaac's Greenhouse and the Penny Wallace '69 Courtyard in a ceremony on October 28. The new greenhouse was made possible thanks to a generous donation by Randy Mehrberg and his wife Michele Schara, parents of PDS alumni Sam '11 and Eric '19, and is named for the son of Sustainability Coordinator Liz Cutler. Ms. Cutler's passion to develop the School's sustainability program, combined with Isaac's radiant personality, inspired the Mehrberg-Schara family. See the full story and photo gallery.

Harvest Festival 2019

Happy throngs of PDS community members enjoyed delicious food and lessons in sustainability in the Garden and surrounding outdoor spaces along with tours of the new greenhouse and courtyard. This year's Harvest Festival theme, "Arts in the Garden," featured multiple student performances and student artwork in Garden areas and Kristy's Meadow.
