Greenhouse Learning Center

glc2 cover Greenhouse Learning Center The new Greenhouse Learning Center allows students to be active participants in the $14 billion national horticulture industry. Here, they learn real-world management and propagation of plant materials in state of the art facilities.


The Greenhouse Learning Center, a $6 million facility replaced OSU's existing teaching greenhouses. The complex is home to six separate greenhouses, a fully furnished classroom, office space, and the Southwood Landscape and Nursery Prep Area, as well as storage space for soil, equipment and chemicals. Greenleaf Nursery, one of North American's largest wholesale nursery growers and long-time partner and supporter of OSU's horticulture programs, committed $1 million toward this new project.

Each greenhouse is independently climate controlled using an automated micro-grow greenhouse system that continuously monitors conditions like temperature and humidity. Other state of the art features include LED and high pressure sodium grow lights, rolling benches and automatic dark shades.

A large foyer provides space for student club meetings. It also houses cutting-edge irrigation systems, intense climate and humidity control and other technology standard in today’s horticulture industry. Check out the student designs for the Greenhouse Learning Center's Outdoor Plaza!

deep water culture


Students are learning and developing deep water culture plants. The plant's roots are suspended in an oxygenated nutrient solution. Soil provides gaps where air is present, thus the water needs to be oxygenated for the plants to survive. Soil also contains macro and micro nutrients for the plants so in hydroponics the oxygenated water is supplemented with nutrients. In a deep water culture, the deeper the water level the more stable the nutrient solution will remain.

Open House


As part of the Greenhouse Learning Center grand opening on August 24, Dr. Bruce Dunn was showcasing some of the new technology like rolling benches, LED lighting, blackout, and an automated climate control system that students will utilize in classes to Rob Haddock and Dr. Cynda Clary, Associate Dean of the Ferguson College of Agriculture. The Kalanchoe in the picture is used in the Principles of Horticulture class for a demonstration on propagation using a viviparous leaf.  The plant is often referred to as "Mother of Thousands" as the leaves generate plantlets.

nutrient film technique

nft system

Matthew Beartrack checks on the nutrient film system. This technique uses a water pump to deliver a constant flow of shallow, nutrient rich solution through the growing area and drains directly back into a reservoir. The growing trays are placed at an angle (supported by a rack or on a bench) to let the nutrient solution flow back into the reservoir.
