Hydroponics for schools is turning ordinary classrooms and cafeterias into living laboratories. Babylon Micro-Farms brings hands-on, soil-free hydroponic farming into K-12 education, empowering students to grow fresh produce year-round while learning science, sustainability, and nutrition. Across the U.S., schools are using indoor micro-farms to spark curiosity, build healthy eating habits, and connect academic concepts to real-world outcomes.

Two stories show what this looks like in practice. One is Stephen Ritz, founder of Green Bronx Machine and a Babylon Micro-Farms Education Ambassador, whose work has inspired educators nationwide to bring vertical farming into the classroom. The other is Bentonville Public Schools in Arkansas, where farm-to-table cafeterias are proving how transformative classroom hydroponics can be for student engagement, culinary innovation, and sustainability.

What Is Hydroponics in Schools, and Why It Matters for K-12 Education

Hydroponics is a method of growing plants without soil, using nutrient-rich water in a controlled indoor environment. In a school setting, that means students can grow leafy greens, herbs, and microgreens right inside the building, no outdoor plot, no growing season, no weather constraints.

For K-12 educators, the appeal is that a single hydroponic micro-farm touches nearly every subject at once:

Science: plant biology, photosynthesis, water chemistry, and nutrient cycles
Technology & engineering: monitoring sensors, automation, and controlled-environment systems
Math: measuring growth rates, yields, pH, and planting schedules
Health & nutrition: where food comes from and what fresh, nutrient-dense produce tastes like
Sustainability: water efficiency, local sourcing, and reduced food miles

That cross-curricular reach is exactly why hydroponics for STEM education has moved from a novelty to a fixture in forward-looking schools.

Stephen Ritz: Bringing Vertical Farming Into the Classroom

Stephen Ritz’s journey began in the Bronx, where he saw firsthand how hands-on learning can transform lives. As the founder of Green Bronx Machine, Ritz has helped students grow over 165,000 pounds of vegetables while boosting school attendance and academic performance.

In 2024, Ritz partnered with Babylon Micro-Farms to accelerate vertical farming in classrooms nationwide. His message is clear: when students grow food, they grow their minds. “The STEM Garden is a powerful tool for teaching across disciplines, science, math, health, and even business,” says Ritz. “It turns classrooms into living laboratories where kids see the fruits of their labor, literally.”

Ritz sees the classroom STEM garden as more than a teaching tool, it’s a way to build an interconnected community of young people across states and countries. “This allows children to all be on the same page in a different book, in a different state, in a different country at the same time and talk about the one thing that is universal, food,” he explains. His vision is for students everywhere to learn about food “the right way, the safe way, the nutritious way, the economic way, and the entrepreneurial way.”

“The STEM Garden makes you want to learn more, ask questions, taste the produce, and get involved, the learning possibilities here are endless,” Ritz adds. “This is what innovation looks like!”

By integrating Babylon Micro-Farms, Ritz helps schools:

Teach STEM concepts through real-life applications
Foster environmental stewardship and healthy eating habits
Build a sense of ownership, pride, and curiosity among students

The partnership has expanded well beyond Stephen’s own classroom, with Galleri Micro-Farm installations at PS 70 and PS 62 in New York City. Both schools marked the occasion with ribbon-cutting ceremonies, celebrating the new farms and the opportunities they bring for hands-on learning, fresh food access, and community pride. These milestones signal a growing movement to bring vertical farming into more schools, empowering students and communities alike.

Case Study: Farm-to-Table Hydroponics at Bentonville Public Schools

In Northwest Arkansas, where farm-to-table dining is part of the local culture, Bentonville Public Schools brings that concept directly into the cafeteria with two Galleri Micro-Farm units, one at Bentonville High School West, run by District Chef David Thornton, and one at Bentonville High School North, managed by Assistant Director CeCe Pedersen. Their mission:

Enhance farm-to-table learning in a region where local sourcing is a priority
Offer fresh, hyper-local produce for school meals
Create visible, interactive experiences for students

Why Bentonville Chose Hydroponic Micro-Farms

For Pedersen, the decision came down to visibility, aesthetics, and ease of use.

“The units fit perfectly into our serving areas, where students can see food growing right in front of them. That visibility sparks curiosity and makes farm-to-table tangible.”

Hydroponics also lets the schools grow year-round without the space or weather constraints of an outdoor garden.

From Garden to Cafeteria Tray: What Students Grow Hydroponically

The farms produce a steady rotation of greens, herbs, and microgreens, including:

Purple kohlrabi microgreens
Arugula
Broccoli sprouts
Pea shoots
Bok choy

These harvests make their way into grab-and-go salads, themed menu days, and specialty recipes like pulled pork banh mi with house-pickled cucumbers and garden-grown dill. Stickers and signage highlight items grown on site, giving students a direct connection between the farm and their plate.

How Classroom Hydroponics Engages Students in STEM

The micro-farms are living laboratories where students see hydroponics in action and connect it to science, math, and sustainability.

“When we first put the garden in, students immediately asked, ‘Are we eating that?'” Pedersen said. “That curiosity is our opening to talk about food origins, sustainability, and flavor.”

How Much Maintenance Does a School Hydroponic System Need?

Running the farms takes about one hour per week using Babylon’s scheduling app for plantings, harvests, and maintenance. A dedicated account manager provides quick solutions, keeping crops on track, a key reason low-maintenance hydroponic systems work in busy school environments.

The Impact: Fresher Food, Stronger STEM Learning, Connected Communities

Freshness & flavor: students are surprised by how much better fresh-picked produce tastes
Operational fit: low maintenance and easy integration into busy cafeteria routines
STEM integration: real-world applications for classroom concepts
Community connection: opportunities to collaborate with local chefs and partners

Thornton sums it up: “The most rewarding part is seeing people’s reaction when they realize this food was grown right here in the school.”

What’s Next for Bentonville

Bentonville plans to expand the variety of crops grown and integrate the farms into new menu concepts, like a Mediterranean-themed bar. They also aim to involve more students hands-on, reinforcing the connection between growing food and growing community.

Bring Hydroponics to Your School

Babylon Micro-Farms’ STEM Garden and Galleri Micro-Farm are more than indoor farms; they’re bridges between education, nutrition, and sustainability. From Stephen Ritz’s work with Green Bronx Machine in the Bronx to the farm-to-table innovation at Bentonville Public Schools in Arkansas, these living laboratories prove that when students grow food, they grow their minds, their confidence, and their connection to the world.

Together, these programs are cultivating healthier students, engaged communities, and a more sustainable future, one harvest at a time.
