What are the disadvantages of perlite as a growing media?

Perlite is one of the inorganic soil components that contribute to soil air circulation and soil support. Vermicelli is another component of soil to extend the discussion in the soil (perlite is much better for this, of course). 

Of course, these two can’t be used traded even though they play the same role in unusual soil for the establishment.

It is interesting to know that perlite is used not only in agriculture but also in building construction and general building.

 Another use of perlite is in pharmacy. It is also used in water purification of municipal swimming pools, and perlite is also used as an abrasive in the production of soap and detergents.




Perlite could be a type of volcanic shaker (SiO2) mined around the world. Perlite is a sporadic, non-crystallized, and undefined rock that contains a lot of water in its structure (compared to its estimate) and is usually formed by the hydration (combination with water) of obedience. This usually happens and usually occurs when there is sufficient heat.

Perlite is an industrial and commercial mineral, which is very practical and useful due to its low density after processing

Perlite and vermiculite are both used to hold water in the soil. However, perlite is more porous and allows more water to escape and flow out of the soil compared to vermiculite. 

Therefore, this mineral is a better choice for plants that don’t like waterlogging. This applies, for example, to cacti or other plants that need well-draining soil.

One of the advantages of perlite for agriculture is that it can absorb many times its weight in water, increasing the ability of the soil to store water and food. 

As a small reservoir in the soil, this substance prevents nutrients from escaping as a result of irrigation. It can also distribute water evenly and continuously in the plant root and prevent its wastage

By creating pores and loosening the nutrient soil with perlite, the movement of roots in the soil is facilitated and better growth is…


Perlite for agriculture

Perlite for agriculture and cultivation is made by heating the perlite, which causes the small amount of water in the perlite to expand and our perlite bursts like popcorn and develops 13 times larger than its single frame

The result is that the coming perlite is very light and includes a thickness of moo and is like a stone of cotton, both light and white! This heated perlite has small air chambers inside.

 If you look at perlite under a microscope, you will see that it consists of many small cells that are glued together. 

This perlite absorbs moisture from the outside, not from the inside, and is therefore particularly suitable for providing moisture to the roots of plants.

Perlite is used to retain moisture and aerate the soil. The best part is that this practical mineral composition is sterile and has a neutral pH.

Green perlite is used for planting plants in non-soil mixtures, for growing cuttings, and for hydroponics. Once you develop plants in perlite, know that the plant can endure fluoride burn, the side effects of which show up as the burning of the tips of clears from houseplants.

Medical warning

Perlite round is known to be dangerously round. So when working with perlite, beware of the dust it creates.

 It is recommended that you cover your mouth and throat when working with perlite to prevent dust from entering your body.

 Perlite dust can aggravate existing respiratory problems and cause eye inflammation. Perlite is not carcinogenic, but some commercial perlites contain fine quartz particles that are known carcinogens.


Medical warning

But the results of its use in clay soils are:

– Creation of sufficient spaces and holes for drainage and air movement

– Reduction of soil cracks

– Prevention of soil compaction

– Improving the distribution and spread of plant roots in the soil


Perlite in clay soils leads to the following:

– Creation of a hole for drainage and gas exchange in the soil

– Reduction of cracks in the soil

– Prevention of compaction, thereby promoting the spread and expansion of roots in the soil and finally promoting the development and growth of the plant
