plant!t perlite 10l bag.
Plant!t Perlite 10l bag is a natural, pH neutral, sterile growing medium derived from volcanic rock and used by gardeners the world over. It can be used for propagation and to mix with potting soil, keeping it loose and light, allowing air and water to reach roots aiding nutrient uptake and general plant health and growth. Great in potting mixes for container growing and when used in general soil enrichment, it can break up heavy clay soils or support growing areas of the garden where wet ground is a problem. It should not be used in recirculating hydroponic systems as it can block drippers or pumps.
- Aides in drainage.
- improves the structure of soils.
- Great as a medium for starting cuttings.
What is Perlite?
What is Perlite? Perlite is a volcanic glass that is heated to 1,600 degrees F. (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. While both perlite and vermiculite aid in water retention, perlite is the more porous and tends to allow water to drain much more readily than vermiculite. As such, it is a more suitable addition to soils utilized with plants that do not require very moist media, such as cactus soils, or for plants which generally thrive in well-draining soil. You may still use a conventional potting soil that contains perlite; however, you may need to monitor watering more frequently than those made up of vermiculite.
