Description

Perlite is a volcanic glass that is heated to 871 C whereupon it pops much like popcorn and expands to 13 times its former size, resulting in an incredibly lightweight material. In fact, the end product weighs only 5 to 8 pounds per cubic foot (2 k. per 28 l.).  The super heated perlite is comprised of tiny air compartments. Under a microscope, perlite is revealed as being covered with many tiny cells that absorb moisture on the exterior of the particle, not inside, which makes it particularly useful in facilitating moisture to plant roots.

There are several reasons why perlite is such a useful additive to gardens and hydroponic setups. They mainly stem from its unique physical and chemical properties:

  • Perlite is physically stable and retains its shape even when pressed into the soil.
  • It has a neutral pH level
  • It contains no toxic chemicals and is made from naturally occurring compounds found in soil
  • It is incredibly porous and contains pockets of space inside for air
  • It can retain some amount of water while allowing the rest to drain away

Perlite contains:

  • 70-75% silicon dioxide
  • Aluminum oxide
  • Sodium oxide
  • Potassium oxide
  • Iron oxide
  • Magnesium oxide
  • Calcium oxide
  • 3-5% Water

This bag contains 3l of perlite.

Add it to any soil to improve its quality.
