This 25 square foot unit grows enough fish and vegetables to completely feed one adult all year long

A 5 foot x 40 foot aquaponic unit can completely feed 8 adults all year long “FOREVER” on less than an hour a day of maintenance.

A 1/4 acre aquaponic farm can hold 20,000 lbs of fish and grow 70,000 vegetables!

Aquaponics is a symbiotic farming model that combines two different techniques to provide water and nutrients to plants in a unique way. As you may imply from the name, Aquaponics combines aquaculture with a hydroponic system. Aquaculture is the technique of raising aquatic animals in tanks, while hydroponics is a system of growing plants inside of water.

These ideas work so well together because the fish actually provide nutrients and nitrogen-fixing bacteria for the hydroponic system, which helps the plants grow.

In an aquaponic system, plants grow faster and healthier than most traditional farming methods.

This technique is actually nothing new, it was used by the Azteks and many cultures throughout Asia and the Americas. However, with modern technology aquaponics has become even more useful.
