Having chosen a hydroponics system you will need to
fill it with a suitable growing medium or soil substrate. The medium
acts as an anchor for the roots and maintains a balance of moisture
and air in the root zone. Soil-less mediums are inert, water
retentive, supportive and sterile, provide good aeration and no
don't contain weeds! |
| Lightweight, porous,
sterile, use 50/50 mix for perfection. Perlite is by far the
cheapest of the growing media.
This is a great medium, it is cheap and
lightweight and amazingly effective. Perlite is a naturally
occurring volcanic rock that is treated in a furnace in a
process known as exfoliation. Perlite is highly recommended
because it has superb capillarity. Capillarity is the
ability to lift moisture from reservoir and it is the key to
the success with Perlite. Perlite does have a tendency to
attract Algae which will appear as a green stain on the
surface, this is nothing to worry about.

| Porous, lightweight, pH neutral and
clean. Great for houseplants and many hydroponic uses. Can
be re-used indefinitely and so are very economical.
These pebbles are manufactured
specifically for plant culture. These are the perfect
growing medium for house plants and almost anything in a
small container. They are however less suitable for large
plants in large pots. This is because they are less
efficient in lifting nutrient form the lower reservoir than
the other media. |

 A
truly modern alternative to soil.
Lightweight,
completely sterile, non toxic, ideal air to water ratio (50:50 when damp),
widely used with most active systems. Holland hydroponics supply Grodan
rockwool and believe it to be the best on the market.
