The lack of knowledge about hydroponics in the circle of plant growers leads to the fact that, often, aero-hydroponics is mistakenly called aeroponics. In fact, real aeroponics belongs to a completely different area. The nutrient solution in the aeroponics system turns into mist-aerosol due to vibrations of the ultrasonic membrane with a frequency of 1.6?2 million vibrations per second (2 megahertz). This frequency allows water to be sprayed onto microscopic particles smaller than 5 microns. Their average value is about 2.5 microns. These dimensions allow the roots to absorb the nutrient solution unhindered. With such a small amount of droplets, the humidity is practically not felt and this pair is called ?dry fog?. It is impossible to call this development a novelty because, since the 1950s, experiments have been conducted, this method has been developed. This technology is used in industrial greenhouses and greenhouses to increase humidity. Its advantage is the minimum size of water particles, which are not deposited in the form of drops on the leaves of plants, which prevents the development of mold and fungal diseases. Pesticides can be added to the steam to enhance plant protection. In the 1980s, unsuccessful attempts were made in Russia to apply this technology to harvest, using warm water diverted from nuclear power plants in greenhouses.
This technology takes oxygenation to a completely different level! Plants get water and nutrients literally from the air (hence the name ?aeroponics?). It was impossible to think of a better way to deliver the nutrient solution to the oxygenated medium. When in the late 1980s, this method began to gain popularity, the impression was that aero-hydroponics would soon become a thing of history. However, this did not happen. In fact, the roots of plants feel so free in this environment that they grow wildly ? due to the above-ground part of the plant. This is good when you want to grow roots, but if you need to get a large plant, it is somewhat annoying! There is another drawback: ultrasonic membranes spray clean water well, but when you dissolve salts in it, they settle on the membrane and block it.
Today you can meet aeroponic systems designed for greenhouses. Most, if not all of them, are intended for rooting cuttings. You yourself can effortlessly build such an installation on low-power foggers, which are sold at any plant-growing store. However, make sure you buy the device you want. There are foggers on the market that are designed to increase the humidity in residential buildings. They often generate mist simply by heating the water. Obviously, this hot fog is no good for you. Such an installation in the course of the experiment ruined all the cuttings in an hour!
Aeroponika is contraindicated for beginners, except for rooting cuttings. For irrigation and fertilizing fast-growing plants need to generate a lot of fog. We?ll have to closely monitor their crops and equipment and be ready to intervene at the first signs of discomfort in plants.
The development of aeroponics was a decisive technological breakthrough. Imagine growing plants from the clouds ? even poets have never dreamed of such a thing! But aeroponics is not ideal yet. Too many technical difficulties, too many roots, and the plant are short. However, aeroponica conquers the imagination ? there is something magical about how roots grow out of the fog. If you want to try, start with rooting the clones in this way before bringing the crop to maturity.
This technology has disappeared from the greenhouse industry and today this term increasingly refers to systems similar to aero-hydroponics. The only difference is that there is no gutter or pot: the entire root felt is suspended in the air and sprayed with mist.
