1-3mm expanded silver vermiculite in soil
Product information : vermiculite
Vermiculite, chemical formula M g × (H2O) [Mg3 × (AlSiO3O10) (H2O)], is a magnesium water inclouded aluminum silic
te
secondary metamorphic minerals of layered structure. It likes mica in form, and usually come from weathered or hydrothermal
alterated black (gold ) Mica. It will present a deflection shape after heat expansion and water loss, liking a leech pattern in form ,
so it gets the name vermiculite .
Vermiculite features
Raw vermiculite will be expanded to many times when heated at 850-1100 °C, poisonless, odorless , corrosion-resistant, Non-combustible , natural refractory properties , Good thermal insulation , low density , Heat-resistant ,sound-proofing .fire-proofing etc .
Vermiculite chemical :

Vermiculite has been used by plantsmen, propagators, growers and gardeners for decades and our standard Vermiculite and Fine
Grade Vermiculite will allow you to improve your seed sowing germination rates and give your seed and potting compost mixes the edge.
Supplied in easily manageable re-sealable bags, both grades of vermiculite - a naturally occuring non-toxic mineral - will benefitseeds and seedlings; the standard is ideal for mixing with seed sowing and potting composts where it absorbs nutrients and
moisture before releasing them near the rootzone, whilst the fine grade is perfectly suited for raising and covering smaller seeds
where damaging soil temperature fluctuations are kept to minimum.
Simply mix the vermiculite with potting compost, use exclusively as a seed sowing medium or cover your seeds after sowing and just watch the results!

In aquaponic and hydroponic systems, soil is replaced by these natural clay pebbles, which are derived from a renewable and plentiful source (clay) so it is considered an ecologically sustainable medium. The clay is formed into pellets and then fired in rotary kilns at 1200Cº. This causes the clay to expand inside, like popcorn, and become porous.
pH neutral, reuseable and structured like honeycomb – the porosity and surface area gives it ideal water retention qualities for growing.
