Horticultural Perlite useful to the home gardener as it is to the commercial grower.
It is used equal success in greenhouse growing, landscaping applications and in the home in house plants.
It makes composts more open to air, while having good water-retention capacity. It is good carrier for soilless plant,
and carrier for fertilizer, herbicides and pesticides and for peletizing seed.
Other benefits of horticultural perlite are its neutral pH and the fact that it is sterile and weed-free.
Agricultural Perlite
as component of soilless growing mixes where it provides aeration and optimum moisture retention for plant growth.
For rooting cuttings, 100% perlite is used.
Studies have shown that outstanding yields are achieved with perlite hydroponic systems.
In addition, its light weight makes it ideal for use in container growing.
Hydroponics Perlite
• 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.
• Avoids wasting of water and nutrients.
