Interns Reflection on Visit to Lincoln’s Farm

On Thursday, July 10th, 2025, the MOA interns — including myself — visited Lincoln’s Farm, where we met Ms. Gardener and her colleagues. We learned vital information about aquaponics, a sustainable farming system that combines hydroponics (growing plants in nutrient-rich water) and aquaculture (raising fish). As Ms. Gardener explained, “Aquaponics may be defined as a farming system that combines growing plants in nutrient solution with the raising of fish.”

Volunteering at the farm gave us valuable hands-on experience with this innovative system. We interacted with tilapia, tested water pH and ammonia levels, and helped harvest lettuce grown in floating rafts. It was fascinating to see how fish waste nourishes the plants, while the plants, in turn, filter and clean the water for the fish. We also learned how to monitor nutrients, maintain system balance, and appreciate the care required to keep both ecosystems healthy. One challenge we encountered was managing algae growth, which we solved by adjusting light exposure and nutrient input.

What stood out most was the hydroponic section of the farm. Rows of fresh, vibrant lettuce — including five varieties like romaine green and red frilly — were thriving. The lettuce was nourished by filtered water enriched with nutrients from the fish tanks. That water, naturally infused with ammonia and beneficial bacteria, provided the perfect growing conditions. It was inspiring to witness such an efficient, clean, and sustainable farming method in action.

Lincoln’s farm produces nearly 5,000 heads of lettuce every week and seeing that level of productivity powered by nature’s cycle was truly eye-opening. This visit gave us a new perspective on sustainable agriculture and the future of food production.
