![]() The emphasis is a regular cycle of nutrient to deliver fresh aerated food to the root, with keep in temperatures down. This technique which could change or never change during the life of the crop insures the plant roots do not dry out. However, this cycle can change depending on the growth stage. Some mist for three to five seconds every 5 minutes. A set time is used to spray the roots for fixed durations. One way to deliver nutrient spray to the roots of an aeroponic system is to use a regular, interval misting cycle. Proper misting on the right schedule will prevent drying of the roots. When moisture is lacking in the root zone of an aeroponics system, plants can begin to senesce (premature ageing, which can result in leaf loss) and transpire less water. When the temperature exceeds preset thresholds, the controller triggers the misters to activate to bring the temperature down. The temperature is continually monitored in the root zone of the plant. ![]() Some of the more complicated aeroponics systems are temperature controlled. The nutrient and spray interval will produce fast growth rates, high yields and healthy roots, as long as the root chamber is kept at temperatures between 62F to 71F with good stability. True aeroponics use a mist of nutrients over the plant roots inside a dark growing chamber. Aeroponics Misting Frequency for Root Growth ![]()
