7 Best Perlite Review And Guide

Did you know that growing food in your garden is the best way to cut your grocery bill? Growing food in your garden gives you all the nutrients the body needs to thrive. This is made successful by incorporating perlite in the soil mix.

Perlite is a glass formed under intense heat. It is a naturally occurring mineral that exists as a type of volcanic glass. Excavated perlite consist; 75% silicon dioxide, aluminium oxide, iron oxide, calcium oxide, magnesium oxide, sodium oxide, and up to 5% water. All these components are essential for a healthy plant. Perlite is used in gardening, hydroponics plastering, ceiling tiles, and masonry. When processed for gardening purposes, it resembles “volcanic popcorns.”

Benefits of Perlite

  1. Inert and stable: It is highly stable and retains its original shape in the soil mixture. Also, it does not change the PH or mineral balance in the soil.
  2. Inorganic: It is entirely inorganic and contains no harmful chemicals and does not transfer diseases.
  3. Neutral pH: perlite pH ranges between 6.5 and 7.5, which is the ideal range for plants to take up nutrients. The neutral ph takes up the acidity or alkalinity of the soil. 
  4. Lightweight: it is lighter than other aggregates used to improve soil drainage. It also offers ease of handling and carriage. 
  5. Porosity: perlite is a highly porous and permeable material. It offers good water retention and movement within the soil mixture. Improved drainage leaves the soil with the optimum moisture needed to spur growth.
  6. Rich in nutrients: It contains a variety of nutrients ranging from Calcium, sodium, magnesium, and other trace elements.
  7. Inexpensive: It is readily available for purchase at garden stores and cheaper compared to other substances.
  8. Improves aeration: It is an excellent material to enhance aeration of the roots system. The texture of perlite allows it to hold more air in between the particles without compaction. This helps reduce the lack of oxygen in the soil or growing medium.
  9. Washable: Perlite is washed, dried to restore its Ph. If the substance is infested with pests, all the grower does is clean the perlite and sterilize it to get rid of pests.
