The Column Farm NL consists of a grow column with 32 plant sites, 8 on each surface, spaced about  6 inches apart.  Plants grow in an outward and upward direction to fill the available and abundant volume.  Natural light from the Sun illuminates the above ground portion of the plants.

A fluid reservoir contains the nutrients to feed the below ground portion of the plants.  A pump lifts the fluid to a misting assembly at the top of the column, producing water droplets that rain down on the roots of each of the plants.  The timing of nutrient delivery may be programmed to a desired number, say 1 minute of water delivery to the plants every 20 minutes.  On time and off time may be set between 1 and 99 minutes.

Germinated seedlings that range in height from 2 to 4 inches get inserted into the grow column.  There the plant reaches maturity, getting light from the Sun and nourishment from the automated fluid delivery system.  The rotating column makes it easy to service plants and to adjust their orientation to the Sun as required.

The Column Farm NL is ideally suited for warmer climates.  At home, it operates on a patio, deck, or in a solarium.   In a commercial environment, a Column Farm NL array operates within the confines of a greenhouse or hoop house.
