Perlite is used in soilless substrate mixes to provide drainage and help retain necessary water for plant growth. It can be mixed with coconut coir media to produce a homemade blend of aquaponic and hydroponic seedling substrate.
- Perlite provides aeration and drainage for soilless substrates, but retains and holds substantial amounts of water that it releases when needed.
- The water-holding ability of Perlite also increases the nutrient holding capacity when water-soluble fertilizers are used.
- Can be used by itself, mixed with topsoil or potting soil, or any other sterile media for drip or passive hydroponic systems.
- Lightweight Perlite does not crush fine stems or root systems, making it ideal for growing delicate plants such as lettuce.
- Chemically inert, does not deteriorate and has an essentially neutral pH.
- As Perlite is sterile, it is free of disease, weed seeds and insects.
- Nontoxic, safe and economical to use.
- One 4 cu. ft. bag will fill approximately 64 one-gallon nursery pots.
