Perlite is a grow medium that is known to be porous, lightweight and inert in nature, often used as a hydroponic substrate. They can easily be recognised as little white rocks.

Hydroponics offers growers a variety of options for gardening in a much more controlled environment. Hydroponics encompasses the use of a wide range of systems, grow media, nutrients and artificial lighting. The use of perlite media in hydroponic gardening has been increasing as years go by. Perlite media comes in different forms, ranging from fine to medium and to coarse grades, all offered by Progrow Hydroponics, each grade serving a different but specific need in gardening.

The use of perlite in hydroponics is quite inexpensive and that is why Progrow Hydroponics offers a variety of options for you to choose from.

Benefits of using perlite media

Perlite is porous in nature, a trait that gives it excellent water drainage and retention capabilities. This factor is crucial and that is why Progrow encourages users to consider it in their gardening projects. This factor plus its aeration capabilities are also very vital in boosting the healthy growth of the plants’ roots.

Because of its sterile and inert nature, the media does not attract soil pests. These soil pests can be very detrimental to the healthy growth of roots thus inhibiting plant growth. Furthermore, perlite has the ability of adapting to the alkalinity or acidity of the nutrient solution added to it because perlite has a neutral pH of 7. However, in case you want to revert to the neutral pH after adding nutrient solutions, all you need to do is wash it off properly and it will return to neutral.

It also has insulating capabilities, which enables the media to guard the roots of the plants in case of any extreme temperature changes. Nevertheless, perlite has a guaranteed long-term service life since it is a substrate. This factor makes perlite re-usable, giving you years and years of service.
