work using the top irrigation method you must apply your
nutrient solution to the medium surface. The solution can either
be done using drip feeding equipment that will administer timed
and measured doses regularly or it can be done by hand once a
day in large amounts, usually in sand.
Passive Sub Irrigation
method allows the water and nutrients to pass to the roots from
the bottom of the medium using capillary action. The medium used
should have big air pockets that will pass oxygen to the roots.
To work using this method situate your container in a shallow
layer of the nutrient solution or on a capillary mat that has
been soaked in it. Choose perlite, clay granules or gravel as
your medium. Refill the nutrient supply occasionally and check
pH balances are approx 6-6.5 to ensure sufficient nutrients are
being taken in.
Flood and Drain (Ebb and Flow)
method you will need a tray that is higher than your container
that is filled with the nutrient solution. Fill the tray with
your medium, best to use clay granules, and plant. Use a timer
that will make a pump fill up the tray with the nutrients, after
which the solution will run back down into the container.
Deep Water Culture
use this method you must hang your plants in a container so that
their roots are submerged in a solution of oxygenated and
nutrient filled water. Plants can be displayed in containers
with their roots threaded through netting or mesh and the heads
sitting on top.
Static Solution Culture
very easy method to do even for beginners. Called thus because
the nutrient mixture is static, the water is still and simply
bathes the roots. Use a container that is ideally dark plastic
but jam jars can be used on a smaller scale. Your container
needs a lid which if id does not come with one you can fashion
out of cardboard ensuring that it fits tightly on the top and is
secured with tape. If using jars or non dark plastic for your
container wrap it in foil to prevent algae growth. Cut out holes
in the lid through which you can put your plant(s). Try to keep
you plants in the centre of the lid. Add water and your nutrient
mixture, try to match up the mixture as to what your plants
need. Research what pH level is best for growth of the species
you have planted and test the mixture regularly to ensure they
are getting the right balance. Extra nutrients or water may need
to be added as the plants grow. Once you have put you dissolved
nutrients into the container top it up with water. If the
container is aerated the solution can be put in up over the
roots, if it is unaerated then you must allow a little gap
between the water and the roots for oxygen.
