This perlite is the best quality product because it is very light weight and pure white. Its large sized granules are approximately of 2mm to 5mm size. Perlite dust is negligible (Approximately 2-4% only).
Due to its extremely light weight, it’s widely used in vertical pots / planters to reduce the weight of potting mix. If weight of potting mix is less, we can also keep bigger plants in the vertical pots.The expanded perlite is full of tiny air bubbles, and its dimpled surface area helps trap moisture. For the same light weight reason, this is used in terrace/balcony gardens as well.
Perlite is use to mix with cocopeat for plant stability and prevent plant from over watering which cause lack of oxygen. Ideal ratio of perlite with cocopeat is 1:3 (33% perlite, 67% cocopeat).
