Perlite is a silica rock, crushed and expanded through a heat treatment.

It’s used generally to mix within substrates, in order to increase the porosity and lightness of the product.

Perlite has many uses in orchards and gardening. Perlite is ideal as a propagation substrate for all types of plants due to its neutrality.

It is widely used to be mixed with substrates, to increase the porosity and lightness of the product.

It is also used for hydroponic crops and can be mixed with sand in cultivation for the propagation of cacti and succulents.

Perlite is also used for plants that spend more time in bags or pots and need to be moved. It is very useful because it has a high moisture retention capacity, porosity and lightness.

It has a structure that contains 5% water inside and that is why it has the ability to expand when subjected to higher temperatures. When perlite expands due to higher temperatures, it acquires a more porous and lighter texture.

Characteristics of perlite:
– It is very light, weighing 125 kg per cubic meter.
– It has a neutral pH.
– Free of pests, diseases and weeds.
– Incorporated into substrates it is ideal because it promotes good aeration and absorbs large amounts of water.
– It is not flammable.
– Its white color reduces the temperature of the substrate and increases the reflection of light, which is important in greenhouses and shade houses.
