Perlite is a natural pH neutral sterile growing medium derived from volcanic rock.
You can use perlite to aid in the breaking up of heavy soils. Just mix with potting soil and it will keep the soil loose and light. This allows oxygen and water to reach the roots aiding nutrient uptake and improving plant health and growth. Perlite is light, odourless, easy and safe to handle.
This perlite is graded at 2-5mm.
Available in Small (approx 1 Litre) or Large (approx 3 Litre) resealable bags.
