Perlite horticultural grade is a type of perlite that is specifically designed for use in horticulture. It is characterized by its lightweight and porous nature, making it an ideal medium for improving soil aeration, drainage, and moisture retention. The horticultural grade of perlite has a density of around 1.2%, which allows it to effectively enhance the physical properties of various soil types.

One of the key benefits of using perlite horticultural grade is its ability to promote healthy root development in plants. The lightweight and porous structure of perlite allows for optimal air and water retention, creating a favorable environment for root growth. Additionally, perlite horticultural grade is sterile and free from weeds, diseases, and insects, making it a safe and reliable choice for horticultural applications.

In addition to its use as a soil amendment, perlite horticultural grade can also be used as a standalone growing medium for hydroponic systems. Its lightweight and porous nature make it an excellent choice for hydroponic gardening, providing ample support and moisture for plant roots. The inert and sterile properties of perlite horticultural grade also contribute to the overall cleanliness and hygiene of hydroponic setups, reducing the risk of contamination and disease.
