What is Bulk Perlite?
Bulk perlite is a form of perlite that is sold in large quantities, typically in bags or supersacks, making it economical for commercial growers and large-scale gardening projects. Unlike smaller retail bags, bulk perlite is often purchased for applications requiring significant volumes, such as landscaping, large greenhouse operations, or agricultural uses.
Benefits of Using Bulk Perlite
- Improved Drainage: Perlite’s structure allows for excellent drainage, preventing root rot and promoting healthy plant growth.
- Aeration: The lightweight nature of perlite increases aeration in soil, which is critical for root health.
- Inert Medium: Perlite does not decompose or release nutrients, making it ideal for plants that prefer controlled moisture and nutrients.
- pH Neutral: Perlite has a neutral to slightly alkaline pH, making it suitable for a wide range of plants.
- Versatile Applications: From horticulture and hydroponics to construction, perlite is a multi-purpose material.
