Get To Know OU’s Leafy Green Machine

Wouldn’t it be super cool if OU had a way to grow its own fresh produce and serve it on campus? Seems pretty healthy, clean and green, right? This is exactly what Housing and Food Services thought when they teamed up with the student organization OUr Earth several months ago to bring a Freight Farms Leafy Green Machine to campus. What is a Leafy Green Machine? Why is it important? What can it do for our campus? Those questions and more are answered below!



This is a Leafy Green Machine, Housing and Food Services’ latest innovative and sustainable investment. Located just north of Cate Main, this system is bringing a 365-day produce-growing season to OU’s campus. The Leafy Green Machine is run by Housing and Food Services with the support of OUr Earth, a student organization dedicated to educating students about various environmental issues impacting the world today.


Through state-of-the-art climate control technology, this 40’ x 8’ x 9.5’ upcycled shipping container is equipped with the tools to harvest crops year-round. The entire system is run by an in-farm controller. Environmental sensors balance temperature, humidity and CO2 levels to ensure a perfect growing environment. A nutrient-rich water solution is distributed directly to the roots of the produce from a closed-loop hydroponic system, which only uses 10 gallons of water a day. A high-efficiency LED lighting system mimics sunlight in order to stimulate photosynthesis. All of these elements come together to ensure an ideal growth environment no matter the weather conditions outside.


The Leafy Green Machine has room to grow lettuces, brassicas and herbs. Everything produced by the farm will initially be used in Cate Restaurants.

This project has tremendous potential and implications for Housing and Food Services. We are providing something that most schools have possibly never heard of. On top of that, we are on the forefront of a new, sustainable, eco-friendly practice that can and will provide us with produce year-round. This can and probably will evolve into something bigger.”

  1. Hello,
    I would love more information on how a person could come and look at this and if you have to make an appointment? A co-worker and myself are very interested in this and would love to see one in person. We live about 5 hours away and would be willing to travel to see it, eat in your cafeteria and whatever else may be involved. Is there anything else in town along these lines? Would love to visit a Farmers Market, Community Garden or anything to do with Farm to school while we are in the area.
    Please let me know. My email is
    Thank you and eager to hear from you.
