Aeroponics

Homemade Aeroponics System

In this system a large container contains several gallons of nutrient solution in the bottom. A high pressure pump pushes a fine, highly oxygenated spray through spray heads that constantly soak the inside of the container with a fine mist of the solution. No growing medium except for air is needed with the aeroponic system because the roots hand down into the container. Occasionally the roots will grow long enough to reach into the nutrient solution in the bottom of the container, but that is not the intent. While being very high-tech and not suitable for the common gardener, it is in high demand due to its fast growth rates. New systems are in the development that are simpler and do not rely on pumps.

Aeroponic Clone

Normally, the aeroponic system is not ideal for home gardeners because it is the most difficult system to master and the most temperamental. It is one of the most high-tech hydroponic systems with individualt parts that can run at very high prices. Also, the fine spray emitters, the basis of the system, will instantly clog if anything except high quality hydroponic fertilizers are used. In addition, pH changes and nutrient imbalances occur more quickly because of the increased absorption rates and high levels of oxygenation. Without a media to protect the roots, plants react to these negative changes more quickly.
Aeroponic clones are being used by some at-home hydronic gardeners. A homemade aeroponic system can be made from a plastic storage bin with two inch holes cut into the lid to hold several two inch netted pots. Cuttings are placed in the netted pots so that half of an inch sticks out the bottom. They are then held in place with expanded clay pellets. The water level should be kept one inch below the bottoms of the pot. Aeroponic clones can be kept moist by an air pump on a timer. Tiny bubbles rush to the surface pop and a very fine mist of water jumps into the air. Clones produce roots more quickly with a series of wet and dry cycles; run it for 15 minutes and then turn it off for 45. The clones should have roots after about two weeks if the water is maintained in the reservoir.

Aeroponic System

Aeroponic clones are successful if it is kept clean and at the right temperature. The water reservoir should start at room temperature and add a B1 supplement to reduce cutting shock and promote stronger quicker root development. Keeping everything close to 72 degrees Fahrenheit promotes the best results.
