What are Perlite ?
Perlite are not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets Perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four to twenty times its original volume.
Character: Non-toxic, flavorless, lightweight, corrosion resisting, netural PH 6.5-7.5 etc.
Size: 100mesh, 200mesh, 0.15-1.18mm, 1-3mm, 2-4mm, 3-6mm, 4-8mm etc.
Color: White.
Bulk Density:(for reference)
1-3mm--------------60-90kg/CBM
2-4mm--------------60-100kg/CBM
3-6mm--------------60-100kg/CBM
4-8mm--------------70-110kg/CBM
Application:
• Green house propagation and growing• Compost aeration
• Container and rooftop gardening
• Bio filtration
Perlite is widely used in the agricultural industry as a soil improver. The characteristics of agricultural perlite that grant the benefits are:
• Water absorption.
Perlite can absorb 2-3times its weight in water. As a result it reduces the cost of watering and energy spend for watering. Considering also the world efforts in preserving water makes the use of perlite in horticulture an ideal solution.
• Aeration.
When perlite contains the maximum capacity of water it has an aeration ration of 56%. Thus creating the necessary conditions for plants to grow.
• Neutral PH.
Perlite has a neutral ph (6.5-7.5) and is chemically stable.
• Insulation.
Perlite provides insulation to the plant’s roots making them less affected by climate changes.
• Life span.
Perlite does not disintegrate through time nor it changes characteristics.
