What is perlite made of, and what are its functions and effects?

1. What materials are it made of?

Perlite is not made of any material, but is a natural substance that occurs naturally and needs to be mined. The acidic lava erupted from volcanoes is perlite. Its appearance is mainly grayish white or light gray, as well as flesh-red, yellowish white, black gray, dark green, gray, and brown. It has a variety of shapes, including shell-like, flake-like, and jagged fractures, and has the luster of pearl. Perlite is non-toxic, will not cause harm to the human body, and has many advantages.

2. Function and efficacy

Perlite has many functions and effects and can be widely used in various fields, such as synthetic glass, rubber and plastic products, pigments, etc., but here we mainly introduce its role in growing flowers at home.

1. Loose soil: Perlite has many holes inside. When mixed with soil, it can transform the soil and regulate soil compaction, making the soil loose and breathable, allowing the roots to breathe normally and absorb water and nutrients normally, which is beneficial to the growth of plants.

2. Absorb water and fertilizer: Perlite can also absorb water and fertilizer, play the role of retaining water and fertilizer, and continuously supply plant growth.

3. Absorb pesticides: Due to its porous absorption capacity, it can also absorb pesticides, playing a role of dilution and slow release.
