Rabo perlite culture bed has different granularity based on millimeter as follows:
1- Perlite 0-2 mm
2- Perlite 3-6 mm
Rabo perlite has a pH close to neutral and is insoluble in most natural environments. Therefore, it does not cause a significant change in the alkalinity or acidity of the culture medium. The characteristics of Rabo perlite can be mentioned as light weight, minerals similar to soil, being sterile, easy and cheap, high air absorption power, increased moisture retention capacity, and resistance to chemical and biological decomposition.
Rabo perlite is available in bulk form (compressor or simple bags).

Perlite:
Perlite is a type of volcanic glass stone with aluminum silicate composition, which has magma water due to volcanic activity. Its difference with other stones is that it expands rapidly due to high heat up to 1200 degrees Celsius, and due to thermal shock, depending on the type of primary stone composition, its volume increases from 4 to 20 times, which is like the seeds of corn that have bloomed and become The form of small glass-like bubbles is formed and it turns into substances with a very low specific gravity of 75-150 kg/m3.
Perlite has many uses, and its use in agriculture is one of the most important uses of perlite. At present, perlite powder is widely used in agricultural industries, especially in European and American countries, which is not very common in our country, and it is necessary for dear farmers, gardeners, greenhouse keepers and those interested in growing flowers and plants to pay enough attention to it. Considering the lack of water in the country and the recent droughts, as well as the increase in air pollution, using this material to create green spaces and trees will help us a lot.
Perlite powder is usually used with different granularities with or without soil for agriculture depending on its type of use. Perlite powder is completely neutral, without petroleum substances and sterile due to baking at high temperature. The general advantages of adding perlite powder to agricultural soils are: water absorption when watering plants, keeping the soil around the roots moist, and as a result, reducing water consumption and the number of irrigations.
Also, proper mixing of perlite with chemical fertilizers and leaf soil is an important factor in the growth and reproduction of plants. This mixture creates an excellent drainage in the soil and keeps the moisture in it as needed. The unmixed perlite is also used as a drainage for the bottom of the pots. In addition, perlite can also be used in soilless cultivation (hydroponics). For the growth and breeding of seeds, fine-grained perlite is often used.
Perlite creates small paths in the soil, where water and oxygen circulate easily and are freely available to the roots. The above is very important because about 98% of the oxygen needed by the plant is absorbed through the roots. In addition, perlite creates drainage around the roots and prevents water accumulation around the roots and suffocation of the plant due to lack of oxygen. Perlite is also used to improve sulfated soils or soils with heavy texture.
In addition, perlite stores three to ten times its weight in water and returns it to the surrounding soil by reducing the soil moisture. Due to the neutrality of this powder, the water returned to the soil does not have any side effects for the plant, and for this reason, it is used in agriculture. It is recommended to use perlite.
