1. Product name : expanded perlite
The material comes from volcanic lava.It is a kind of amorphous, glassiness volcano that contains crystalline
water inside. For expanded perlite has low density and low heat conductivity characters, it is widely used in
construction and manufacturing fields,lightweight plasters and mortars, insulation, ceiling tiles and filter aids.
In horticulture, it makes composts more open to air, while having good water-retention capacity. It is good carrier for soilless plant.Since last few years,expanded perlite is more and more
popular in cryogenic use. Horticultural Applications In horticultural applications, perlite is used throughout the
world as a componet of soilless growing mixed where it provides aeration and optimum moisture retention for
superior plant growth. Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and
pesticides and for peletizing seed.

5.In horticultural applications
Agricultural Perlite is used throughout the world as a component of soilless growing mixes where it
provides aeration and optimum moisture retention for superior plant growth. For rooting cuttings, 100%
perlite is used. Studies have shown that outstanding yields are achieved with perlite hydroponic systems.
Other benefits of horticultural perlite are its 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.
Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and pesticides and
for pelletizing seed.
Horticultural perlite is as useful to the home gardener as it is to the commercial grower. It is used with
equal success in greenhouse growing, landscaping applications and in the home in house plants.
benefites of Hydroponic culture:
- Horticultural perlite provides more constant moisture status aroun the roots at all times irrespective of weather
- or stage of root growth.
- Perlite ensures more even watering throughout the grwoing area.
- Thera is less probability of over-watering with horticutlural perlite.
- Perlite culture avoids wasting of water and nutrients.
- The use of perlite eliminates the need to grade growing floors accurately.
Other horticultural applications for Perlite are as a carrier for fertilizer, herbicides and pesticides and for pelletizing seed.
Horticultural Perlite is as useful to the home gardener as it is to the commercial grower. It is used with equal success in
greenhouse growing, landscaping application and in the home in houseplants.
