Perlite is lightweight, easy to handle, and odorless. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. Perlite is used in soil mixtures to improve ventilation and alter the soil substructure to keep it loose, resist compaction, and well-drained. Fragmentation occurs when a stem or shoot detaches from the main unit and grows into a separate plant. You can also use it with other additives or as a standalone growth medium. The finer stuff is also useful, but it’s used for rooting cuttings or in quality seed-starting mixtures as the provided drainage stimulates rapid root production. Here’s the point: When it comes to air porosity, coarse perlite has the highest, and thus it offers the most drainage capability and helps to make sure that your plant’s roots can breathe properly. Horticultural perlite is used as a component in soilless growing mixes, a growing medium for rooting cuttings, or as a hydroponic growing media.

Perlite is one of the most suitable ways to improve the quality of potting soil and multi-purpose compost â and it’s good for tomato plants. Both perlite and pumice help to encourage soil drainage and boost oxygen levels in clay soils. 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. But down below, the root system must soak it up from the soil. Besides that, perlite has higher air porosity and better drainage effects compared to vermiculite. Since it is porous, perlite allows excess water to drain more quickly than vermiculite and helps to boost soil aeration.
