Purpose: Leca (Lightweight Expanded Clay Aggregate) is a type of clay pellet that is commonly used as a growing medium to provide excellent drainage, aeration, and moisture retention for plant roots.
Application: Leca can be used in hydroponic systems, such as flood and drain, drip irrigation, and deep water culture. It can also be used in traditional potting mixes for indoor and outdoor plants, as well as for green roofs and landscaping projects.
Compatibility: Leca is compatible with a wide range of plants and can be used for both hydroponic and soil-based cultivation. It is particularly beneficial for plants that require good drainage and aeration, such as succulents and orchids. Leca is also compatible with various fertilisers and can be reused multiple times with proper cleaning and sterilization.
Suited for: a wide range of plants including succulents, orchids, and carnivorous plants.
8-16mm LECA is a larger-sized lightweight expanded clay aggregate with pellets that range from 8 to 16mm in diameter. It provides good drainage and aeration to plant roots and is suitable for use in larger hydroponic systems or as a standalone growing medium in larger containers. It is less likely to compact over time and can support larger plants effectively.
