Diferencias entre perlita y vermiculita

Differences between perlite and vermiculite

Contenidos

Vermiculite and perlite have become the most popular raw materials in the growing and gardening sectors. These two materials, together with pumice, are three very cost-effective additives to optimise the quality of the substrate.

Let’s take a look at their characteristics, uses and differences.

What is vermiculite and what is it used for?

Vermiculite, mineral and plant substrate

Vermiculite is a mineral made up of aluminium, magnesium and iron silicate. Its main characteristic is its capacity for expansion and exfoliation when it reaches high temperatures, as its volume increases between 8 and 20 times. It is very beneficial as it is able to absorb and rescue nutrients such as potassium, magnesium, calcium and phosphorus.

Vermiculite is a substrate that is used in gardening and agriculture, as well as in industry and construction.

At Panadero we use vermiculite in our wood stoves. It can be found inside the combustion chambers. Vermiculite guarantees maximum safety, being able to withstand large amounts of heat and extreme temperatures.

What is perlite and what is it used for?

Perlite plant substrate

Perlite is a mineral that comes from volcanic rock and is very rich in silicon. Like vermiculite, perlite is also heated in order to expand its particles. It is a mineral that retains water and air.

Perlite substrate is mostly used in vegetable gardens and gardening. You can find perlite for plants in many shops, both online and offline. If you want to buy plant pearls or perlite for soil, we recommend that you find out about the different grain sizes, as their use depends on their size.

Differences between vermiculite and perlite

There are major differences between perlite and vermiculite. The main difference is that vermiculite mixes with the soil and helps to retain water. Perlite, on the other hand, increases drainage to the soil and mixes with it.

Vermiculite is used in different sectors. Its uses range from being an additive for plants that need to be kept moist, to being used as a packaging material for hazardous materials, in fireproof cementitious structures and even to create building parts.

Perlite is used as a substrate for plants. It is used when plants need to dry out before watering and to reduce fluctuations in soil temperatures, as well as being beneficial for drainage and aerating vegetable gardens.
