Vertical Farming and Microgreens

Vertical farming is the practice of producing food in vertically stacked layers, such as in a skyscraper, used warehouse, or shipping container. The modern ideas of vertical farming use indoor farming techniques and controlled-environment agriculture (CEA) technology, where all environmental factors can be controlled.

MicroGreens are a tiny form of young edible greens produced from vegetable, herb or other plants. They range in size from one to one and a half inches long, including the stem and leaves. A microgreen has a single central stem.

A Vertical Farm of MicroGreens uses pure water, conventional seeds on 100% organic coconut fiber hydroponic growing pads, as the seed bed, and natural bamboo stakes to keep the fiber off the tray bottoms resulting a true hydroponic environment with seeds-to-harvest in about a week. They sell to local restaurants, with roots attached, for about $30 (in 2016) per tray. They use about 1 cup of water per day per tray and electricity for 12-volt LED lighting for an estimated total cost of $6 (2016 prices) to grow one tray.
