LAF Vermiculite is available in economical and bulk 100-litre bags and three different grades: fine (called Due-Lit), medium (called Vermigro), and coarse (called Quatro Lit). This horticultural-grade vermiculite is suitable for improving soil structure, boosting moisture retention, and providing other gardening benefits. It can be used on its own or blended with perlite and other organic growing mediums. It is particularly well-suited for seed starting, propagation from cuttings, and transplanting. It’s also a popular choice for growing vegetables.
Vermiculite is a mineral similar to mica. During Exfoliation, Vermiculite is subjected to intense heat and expands up to twenty or more times its original size. As Exfoliation occurs, millions of microscopic gaps are created within the plates, which give Vermiculite excellent insulation and water retention properties. Vermiculite is lightweight, air-entraining and highly absorbent. It is inert and does not harm the environment. It is chemically neutral and sterile immediately after exfoliation.
