At Hilltop High School in rural Alberta, a student-led climate solutions contest sparked a hydroponics project that now operates in the lunchroom. Students installed a rain barrel for water supply and a composter to recycle food waste, creating a closed-loop system that grows vegetables with significantly less water than conventional agriculture. Student lead Lucas Boudreau said the project provides a sustainable vegetable source for the school, while teacher Ms. Doepker noted students pursued research far beyond classroom requirements.
In Calgary, Robert Thirsk School paired its hydroponics room with a rooftop weather station so students can track real-time climate data alongside food production. The garden grows basil, tomatoes, kale, arugula, lettuce, mint, and morning glory flowers year-round and serves as a living classroom for more than 200 visiting students, including an ongoing student-led lettuce growth trial. Teacher Ryan Morgan said the program helps urban students connect with food systems and rethink sustainable production.
At the Individual Learning Centre in Whitehorse, Yukon, where outdoor growing seasons are short and fresh produce is expensive to ship, students built a garden from scratch using locally sourced materials. They coded their own automated watering and nutrient delivery systems in collaboration with local universities and farms. The system now produces tomatoes, kale, arugula, lettuce, basil, mint, and morning glory flowers year-round, supplying the cafeteria and reaching 340 students and community members.
Student Crystal Charlie highlighted the contrast of growing fresh food indoors while temperatures outside drop to -40°C. Teachers report that students are taking ownership of the space in ways that extend beyond gardening, linking concepts of sustainability and food systems to daily, tangible experience. Across all three sites, the gardens operate without requiring specialized staff or pre-existing clubs, relying instead on student curiosity and initiative.
The projects demonstrate how indoor gardens can function in vastly different environments — rural, urban, and subarctic — while delivering measurable food output and hands-on learning. Each school adapted the model to local conditions, from rainwater capture in Alberta to automated controls in the Yukon. The produce is used in school cafeterias, and the systems serve as platforms for experiments and cross-curricular study.
Organizers with N:OW for Net-Zero, which supported the initiatives, say the gardens make climate action concrete for students who can see, touch, and eat the results of their work. The approach requires no field, favorable weather, or specialist teachers, only space, light, and student engagement. Outcomes include reduced water use, lower food-transport emissions, and year-round access to fresh vegetables in regions where that is otherwise difficult.
When Students Grow Their Own Food, Something Bigger Takes Root
