Description
Perlite Premium 100 L is a perlite additive for building a lighter, cleaner and more even substrate mix. Compared with standard perlite, the premium grade stands out for double screening, a defined grain size and a very low dust content, which makes it especially suitable for hydroponics, pure media and high-end grow substrates.
Double screening leaves far fewer fines than basic grades, so handling is more pleasant and the substrate structure is cleaner – a clear advantage when mixing larger quantities. Perlite stores water and oxygen well and is free of pathogens. RHP quality mark for controlled quality.
