Description of Expanded Perlite
Product Name: Perlite,Expanded Perlite,Horticultural Perlite
Particle Size: 1-3mm 2-4mm 3-6mm 4-8mm.etc
Features:
1.Perlite, a material composed of super-heated volcanic glass, resembles pure white foam pellets.
2.Perlite granules feature small cavities on their surface that trap and hold moisture,which helps retain
moisture in an otherwise quick-drying potting mixture.
3.Lightweight perlite also aerates soil because the lightweight pellets prevent the organic ingredients
in the soil mix from compacting.
4.Perlite has an alkaline pH between 6.5-7.5,which can cause fluoride burn on foliage plants that prefer
more acidic conditions.
Usages:
Gardening,Horticultural,Agriculture cutting seedling,Soilless Cultivation,Soil Improvement,
Hydroponics,Green Plant landscaping.etc
Advantages:
- Perlite isclean without disease,poisonless,tasteless, sterile,light weight,non-combustible,alkali resistant.
- Permeability is good.
- Preserving soil, water, and nutrient.
- PH is 6.5-7.5

Horticultural Expanded Perlite Applications
Agricultural Perlite is widely used as a component of soilless growing mixes where it provides aeration
and optimum moisture retention for superior plant growh.
For rooting cuttings,100% perlite is used.
Perlite are also as a carrier for fertilizer,herbicides and pesticides and for for pelletzing seed.
Gardening Perlite:
Horticultural perlite is as useful to the home gardener as it is to the commercial frower.
it is used with equal success in greenhouse growing,landscaping applications and in the home plants.
Hydroponics Perlite:
Studies have shown that outstanding yields are achieced with perlite hydroponic systems.
With neutral PH and the fact that it is sterile and weed-free.In addition,its light weight makes it ideal for
use in container growing.
Benefites of Hydroponic culture:
- The crops growing strong,with high yield and good quality;
- Saving water,fertilizers,labor and time;
- Less pest and disease damage,avoiding soil continuous cropping obstacles;
- Greatly expanding the agricultural production space;
