At Winona Senior High School in Minnesota, sophomore Miriam Jackson manages six hydroponic Flex Farms that grow up to 200 pounds of lettuce each month. These fresh greens are served in school lunches for over 800 students, making school meals more nutritious and local.

Developed by Wisconsin-based Fork Farms, Flex Farms are indoor hydroponic systems designed for small spaces like schools. Jackson handles seed germination, water monitoring, and pH balancing for the crops, mostly leafy greens like iceberg lettuce. While harvest days require extra help, she manages most tasks independently, spending nearly 15 hours a week on the project.

With sleeves rolled up and gloves on, young students at Redford Union Schools are growing leafy greens that show up later in the lunchroom as kids learn science, responsibility and even some healthy habits along the way.

Thanks to a new hydroponics program launched this year at both Hilbert and Beech elementary, the district's elementary STEAM classes are growing lettuce without soil – just water, light, curiosity and lots of smiles.

The project began in January with sixth graders planting the first crop of romaine lettuce. Since then, students in first through sixth grade have gotten involved in everything from monitoring the hydroponic system to harvesting.

The students harvested nearly 50 pounds of fresh lettuce, grown inside the school using the Flex Farm hydroponic system from Fork Farms.  Winona Area Public Schools says this is the first set-up of its kind in the state and allows Winona students to grow close to 200 pounds of fresh lettuce each month for the school's salad bar in the cafeteria.

Hydroponics is a method of growing plants in nutrient-rich water instead of soil and Winona Area Public Schools says it provides numerous benefits for student engagement, critical thinking, and problem-solving skills by combining hands-on experimentation in real-world farming scenarios.  FFA Officer & Farm Manager, Miriam Jackson, and school's nutrition staff have been maintaining these Flex Farms learning valuable lifelong skills as they test pH levels, manage nutrient levels, and examine crop cycle management.

The Wisconsin Department of Public Instruction recently embarked on an exciting journey with its new Fork Farms Flex Farm hydroponic grow tower. On January 13, 2025, the first lettuce seeds were planted, which were ready for transplanting into the tower by February 3. Throughout February, the seedlings grew into mature lettuce, and by March 3, the first harvest was ready! The freshly grown lettuce was served at the WI DPI School Nutrition Team’s monthly meeting and potluck—where it received rave reviews.

The hydroponic adventure didn’t stop there! The lettuce regenerated throughout March and on March 31, the Flex Farm was showcased at the Wisconsin State Capitol for a special Farm to School event. Visitors were invited to explore the grow tower and take home free lettuce and bean seed packets, branded with the Wisconsin Farm to School logo.

Students at Crivitz Middle School are getting their hands dirty in the science department, learning what it takes to grow their own food -- right inside their classroom.

Thanks to a grant from Provident Health Foundation, the science program received an indoor hydroponic system.

"They get to see how their food is grown and they are involved in that process. Taking the food and giving it directly to cafeteria where the students see it on display," says science teacher Shane Graves.

Paul Karpawich, Program Director for Uplift NH, hosted a presentation and discussion about driving environmental education and problem-based learning in school curriculum across New Hampshire.

Paul shared his organization’s success in working with schools and students to launch and sustain food waste diversion and composting projects and offered networking space to replicate similar projects in your own school.
