What is hydroponics?
Soilless Agriculture
Back to botany! What do plants need?
• Light
• Nutrients/Oxygen
• Water

What is hydroponics?
• Water culture systems –• Nutrient film techniques-- trough or tube as the container through
which a constant, thin film of nutrient solution flows
• Aeroponics- suspended plants, nutrient mist delivered by vaporizer
• Aeration method – aquarium with tray, roots grow down into solution, inert material supports plants (stem)
• Aggregate Systems –• Inert material around roots, flood and drain OR tickle feed method.
• Tube culture!

Aggregate Systems
Use some inert sterile (or serializable material) rockwool, clay pebbles, gravel, perlite, vermiculite, sand, or foam chips.
To support the root system and plants.

What is aquaculture? Aquaponics?
Aquaculture is fish farming or fish production. Warner’s aquaculture systems allow for water to recirculate, drain waste and keep fish growing. With bacteria monitored continuously fish production happens at the highest water purity levels.
Combining the aquaculture and the hydroponics systems results in a mutually-symbiotic and sustainable system known as aquaponics.

• The Hydroponic Society of America is a 501c3 non-profit organization formed in 1976 in Berkeley, CA. Our extensive experience is in the disciplines of lighting, engineering, controlled environment agriculture, hydroponics, and more. The HSA has a rich history of being involved with leading industry scientists and groups like NASA, the FFA, 4H and a number other national and international organizations. The Hydroponic Society of America works with some of the leading plant scientists and controlled environment application engineers in the industry.
