HydRocksTM is produced
by fully calcining clay at temperatures in excess of 2000 degrees
Fahrenheit.
This inert, ceramic material is available in a variety of particle sizes
- Fine, Medium and Coarse.
LIGHT
WEIGHT The bulk density of HydRocks
is much lower than that of soil, sand and many types of soil
amendments - a definite advantage during transportation,
handling and installation. Yet it is strong and durable -
providing long-term aeration in potting mixes and rooting
media.
NEUTRAL pH HydRocks will not release carbonates
or other chemicals that affect the pH of potting mixes. It
is chemically stable, but can be treated with chemical supplements
to meet the pH requirements of a particular application.
CHEMICALLY INERT Because HydRocks has been fully
calcined at temperatures in excess of + 2000 degrees Fahrenheit,
it is a ceramic material. It will not compress, decompose,
or react with agricultural or horticultural chemicals. HydRocksTM
has a low cation exchange capacity.
NO SHRINKAGE HydRocks is completely inorganic,
and will not decompose like organic materials such as peat,
sawdust, composts and bark. HydRocks maintains its porosity,
providing superior aeration for optimum plant growth and healthy
root structure. Added to soil mixtures at a rate of 10% to
20% by volume, HydRocks prevents soil compaction and promotes
root growth.
COLOR Because of its natural color, HydRocks blends
well with other soil materials. It also makes excellent mulch particularly
in high traffic areas. SOIL INCORPORATION HydRocks is an ideal amendment for raised beds used
for the production of roses and other ornamental plants. When incorporated
at a rate of 15 to 25% by volume, it improves drainage and aeration, promoting
plant growth. HydRocksTM is also an ideal medium for hydroponic production
systems.
MOISTURE RETENTION HydRocks allows free drainage, but also absorbs up
to 30% of its weight in water and water born nutrients. Water and nutrients
are slowly and steadily released as the soil dries. HydRocksTM particles
will not float up or sink out of a blended medium.
