Aeroponics is a plant-cultivation technique in which the roots hang suspended in the air while nutrient solution is delivered to them in the form of a fine mist. The basic principle of aeroponic growing is to grow plants suspended in a closed or semi-closed environment by spraying the plant’s dangling roots and lower stem with an atomized or sprayed, nutrient-rich water solution. Root growth increases yield, that is the mantra of marijuana. The larger the root system, the more nugs it will produce. That is the most important factor when considering the aeroponic method. With enough nutrients and without the restriction of a medium, the roots can grow unimpeded. This can also be a very unforgiving method.
