InFarm is a self-contained agricultural center that lets you shop for food that is literally as local as possible. InFarm designed new technology—including some patented techniques—to make the tiny farms possible. It uses every centimeter of space. Unlike a state-of-the-art greenhouse, where seedlings might be raised in a dense area but later moved, all stages of plant growth happen in a single area.
