Three forms of hydroponics
September 9, 2011 @ 1:00 pm
There are 3 forms of hydroponics they are Agroponics, Aeroponics and Aquaponics.
The definition of hydroponics is literally working water…or as used today the science of growing plants without soil.
Agroponics
A solid, inert medium such as coconut coir, vermiculite or perlite that provides support for the plant roots. As in liquid systems, the nutrient solution is delivered directly to the plant roots.
Aeroponics
The process of growing plants in an air or mist environment without the use of soil or an aggregate medium
Aquaponics
The symbiotic cultivation of plants and aquatic animals in a recirculating environment.
Hi Larry,
I enjoy your articles. I have a question about this one…in which one of these three forms would you classify NFT (small film of nutrient flowing through a channel)?
Thanks again for the good reading,
Marilyn
NFT would fall under an Aquaponics system. The roots are suspended in air with a film of nutrient flowing in the bottom of the channel.
