Perlite Stones
Perlite Stones
Perlite is a volcanic stone that ranges in color from gray to white. It is composed of several materials, including aluminum silicates, sodium, potassium, and crystallized water. The raw perlite is crushed and dried, then heated to a very high temperature of 900-1000 degrees Celsius. This causes it to expand as the hot air escapes, and the crystallized water inside rapidly evaporates, resulting in its volume increasing by 4 to 20 times its original size. Thus, we obtain lightweight, whitish-gray particles that contribute to improved agricultural germination processes.
Benefits of Perlite
- Perlite enhances soil ventilation due to the presence of voids and pores. It also promotes root growth because it contains silica. Additionally, the presence of perlite in the soil makes it lighter, which helps roots grow more efficiently.
- It serves as an ideal medium in various agricultural processes, ranging from seed germination to propagation.
- Perlite is commonly added to sandy soil or garden soil due to its importance in creating good soil for plant cultivation.
- It is also used in creating soil mixtures by blending it with vermiculite, which provides significant benefits and results in good soil for seedlings.
- Moreover, perlite has great significance for soil in indoor plant cultivation, where a mixture of 50% vermiculite and 50% perlite is used.
- It is also utilized in outdoor plant cultivation by mixing 50% sand, 20% clay soil, 10% compost, and 20% perlite.
