Farm in a Box
Aqua Vita is housed in an insulated warehouse, and is essentially nature in a box. That means Mark Doherty and his team have to regulate every environmental variable to ensure that their plants and fish thrive.
Aquaponics in a Nutshell
A fish tank connected to a plant box, the two feeding each other in equilibrium.
The lettuce seedlings begin like this: tiny stems building their root structure before getting transferred to larger plots.
In what's called "deep water" farming, the lettuce sits in a foam raft floating on the water. Plants can be packed more densely than in traditional agriculture, since the nutrient-rich water doesn't have the same limitations as soil.
The little squares the plants sit in aren't soil—they're rock wool, a substance made by superheating sterile salt rock into fibers, then spinning it into other shapes.
The roots float in the water, sucking up nutrients that pass by.
Some plants take better to growing in a substrate rather than in water directly. These beet greens are in a tub of rocks instead.
Grown this way, lettuce is ready to harvest after 28 days, which means that Aqua Vita can adjust their inventory with just a few weeks' notice to respond to special requests from chefs or changing market interests.
The tilapia Aqua Vita raises are grown for food, but they also provide the base nutrients for the plants through their waste products. Yup—fish poop.

Mark fell into farming almost by accident. But a good price on a warehouse and lots of research later, he's become an aquaponics leader.
