Golden and Silver Horticultural Vermiculite for tomato growing media
EXPANDED VERMICULITE is a mineral similar to mica. During a process called Exfoliation, Vermiculite is subjected to intense heat and can expand up to twenty times its original size. As Exfoliation occurs, millions of microscopic gaps are created within the plates which give Vermiculiteexcellent insulation and water retention properties. Besides these highly beneficial qualities,Vermiculite is lightweight, air entraining and absorbent. It is also environmentally friendly, chemically neutral and virtually sterile after exfoliation.
Characterustics: Lightweight, clean, non-abrasive, Pourable, natutally absorbent materials, fireproof etc.
