Vermiculite ...a
mined mica type mineral with a neutral pH. It has been expanded by heat to
form sterile fan-like particles which hold water, nutrients and air which
offers good aeration and excellent water holding capacity.
Our coarsest horticultural grade of Vermiculite. Used for soil mixes,
potting plants and planting. Extra Coarse A4 can be used alone as a
complete soil substitute for starting seeds, root cuttings and potting
plants, or mixed with soil for most garden uses. Extra Coarse is the
lightest, cleanest, highest water absorbing Vermiculite available.
Odorless, sterile and chemically inert, the dust has been screened out for
convenient handling. |
