Growing
plants hydroponically can be a daunting task for any gardener. There
are a lot of materials and information that has to be acquired before
anything is grown. A hydroponic kit is often the best way to start,
even for advanced gardeners using soil, because there are many differences
in the process. The big difference that experienced gardeners have trouble
with is the fact that once the solution is flowing around the roots,
no other watering has to be done.
Many gardeners are used to watering plants periodically, but the only
thing that must be done periodically with a hydroponic kit is checking
the nutrient solution, making sure there are enough nutrients and that
the pH is correct. Once the kit is set up, there is very little maintenance
that has to take place. Setting up the kit is the difficult part.
Depending on the scope of the project or farm, a hydroponic kit contains
at least one channeled container, a pump and a nutrient solution. The
channels must be set up properly, ensuring that they are water tight
so no solution escapes, and that the pump functions properly. When the
system is running there should be no pools of water in the channel,
the water should form a thin film along the bottom that is not too deep.
This is where the roots will absorb the nutrients, but they need to
be exposed to the air as well. Finding the right angle for the channels
is essential for the process to work correctly.
