[GOLD LABEL] Gold Label Perlite - 100L

The perlite is a volcanic rock which, once expanded, is in the form of more or less small, airy and very light white-sen microphone. A natural material, capable of gorging on water to gradually restore it to the plant, a bit like micro-reservations. Neutral and inert, it has no influence on the quality of the earth or on its pH. The perlite is used in mixture in substrates, at the rate of 30 to 50 %. It is appreciated for its ability to lighten and drain the earth and improve its structure and its stability. It is also used pure for cuttings and sowing and in hydroponics.
