Olomana Gardens / In a concrete jungle, green dreams are made of aquaponics. How it works: Aquaponics combines aquaculture (fish farming) and hydroponics (soil-less farming in nutrient-rich water). The system relies on fish waste and water to provide the nutrients for the fruits and vegetables. It’s an ecosystem that relies on very few inputs–like chemical fertilizer or water–because it’s organically fertilized water is constantly recycled.
It’s all a bit technical, so a class at Olomana Gardens is extremely helpful. Aquaponics classes are available at Olomana Gardens for $50 a person, during which students have the opportunity to study Glenn Martinez’s 300-gallon tank. It’s filled with 100 tilapia and growbeds with an assortment of fruits and vegetables like tomatoes, onions, tapioca and chard. Martinez also builds home systems–fish and all–for clients. Prices range from $700 to $3,000, depending on size.
