DIY Vertical Aquaponic Farm For Small Yards & Areas
This low-cost vertical aquaponic system can grow leafy greens, herbs and raise fish for a small family year round, and it fits in a 5' by 3' space. Sean Brady, the aquaponics projects coordinator at the Center for Sustainable Aquaponics and Nourish the Planet in Loveland, Colo., showed us how to build a system from scrap he found around the greenhouse. We published a version of this how-to guide at engineeringforchange.org, and it's one of the good ones, so we'd like to share it with Instructables, too. What it is A vertical aquaponic system grows vegetables without soil in columns above a fish tank. By growing vertically, you can produce about twice the amount of plants as you can with a hydroponic system of the same area. One five-foot tower can produce more than 200 heads of lettuce per year. The system puts fish waste to work as fertilizer for crops. You do have to replace lost water as needed, power the pump and feed the fish. Build time About two hours.
