Product Description
Product name : expanded vermiculite
Vermiculite, chemical formula M g × (H2O) [Mg3 × (AlSiO3O10) (H2O)], is a magnesium water inclouded aluminum silicate
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 .

Horticulture Vermiculite :
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 benefit
seeds 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!
vermiculite has the following benefits
- Inorganic, inert and sterile
- Non abrasive
- Ultra light weight
- Free from disease, weeds and insects
- Slightly alkaline (neutralized with peat)
- High cation-exchange (or buffering exchange)
- Excellent aeration characteristics
- High water holding capacity
- Insulating
Vermiculite is an incredibly useful growing medium. Horticultural vermiculite can be used for many beneficial
purposes in the garden and can aid and assist in successful propagation, cuttings and plant raising.
One of the best uses of vermiculite is the plant propagation arena. Vermiculite is particularly useful when
sowing fine to very fine seed. Instead of covering the seeds with a covering of compost, which can be very
heavy on tiny seeds and can also form a hard cap, making germination very difficult, a small quantity of
vermiculite can be used. This is very light and presents no restriction or check on growth, the seedlings can
easily break the surface and, because of the lightweight granular texture of vermiculite, it does not form a
cap on the top of the growing container or seed tray.
Vermiculite is also used widely in seed and potting compost mix, as well as with container plant pots, to
provide a lighter, more friable compost mix.
Agricultural perlite
Agricultural Perlite is used throughout the world as a component of soilless growing mixes where it
provides aeration and optimum moisture retention for superior plant growth. For rooting cuttings, 100%
perlite is used. Studies have shown that outstanding yields are achieved with perlite hydroponic systems.
Other benefits of horticultural perlite are its neutral pH and the fact that it is sterile and weed-free. In
addition, its light weight makes it ideal for use in container growing.
Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and pesticides and
for pelletizing seed.
Horticultural perlite is as useful to the home gardener as it is to the commercial grower. It is used with
equal success in greenhouse growing, landscaping applications and in the home in house plants.
benefites of Hydroponic culture:
- Horticultural perlite provides more constant moisture status aroun the roots at all times irrespective of weather
- or stage of root growth.
- Perlite ensures more even watering throughout the grwoing area.
- Thera is less probability of over-watering with horticutlural perlite.
- Perlite culture avoids wasting of water and nutrients.
- The use of perlite eliminates the need to grade growing floors accurately.
Other horticultural applications for Perlite are as a carrier for fertilizer, herbicides and pesticides and for pelletizing seed.
Horticultural Perlite is as useful to the home gardener as it is to the commercial grower. It is used with equal success in
greenhouse growing, landscaping application and in the home in houseplants.
