Vertical Growing Systems (SA) (Pty) Ltd uses aeroponics in the process of growing barley/oats or other animal sprouting feeds. Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium. Aeroponic culture differs from both conventional hydroponics and in-vitro (plant tissue culture) growing. Unlike hydroponics, which uses water as a growing medium and essential mineral to sustain plant growth, aeroponics is conducted without a growing medium. Because water is sometimes used in aeroponics to transmit nutrients, it is sometimes considered a type of hydroponics.

Aeroponic crop production is not a novel practice. Even as far back as 80 years ago, Great Britain’s agriculturalists practiced the ‘crop-a-day’ culture. The highly nutritious, vitamin- and mineral-rich sprouted forage was fed to various livestock and birds. (Harris, 1992)

For every 1 kg of seed, 6.2 to 7.2 kg of sprouted fodder is produced in only eight days

GreenFeed® Growing System Standard designed units supply a daily capacity of upto 5 Tons

The Units are SEMI-AUTOMATED UNIT, where all you need to do is remove the fodder, wash the trays and replenish the trays manually.

All other aspects of growing barley/oats green feed are addressed in this semi-automated computer-controlled environment, including water filtration, seed misting; grow-room hygiene; grow-light control; air-flow control; air purification; humidity and temperature control, cleaning and sterilisation controls.
