assignment which is submitted to the school, marked by the school’s
tutors and returned to you with relevant suggestions, comments and if
necessary, extra reading.
What is Hydroponics?
Hydroponics
is the process used to grow plants without soil and literally means
“working water.” The grower is taking control of the plant’s root
environment and losing the benefit of mother nature’s finely tuned
mechanisms which normally control part of the plants development. So
therefore, when you remove the soil from a plant and take control of its
roots, it is essential that you have a good understanding of how it
grows.
Hydroponics is not an easier way
to grow plants! It is a more controlled way of growing plants. However,
it is not a magical way to grow plants either. Anybody can grow plants
in soil with reasonable success but to grow plants in hydroponics, you
must understand how the plant grows, so that you can control the light
and temperature, water, oxygen and nutrients in the root zone. These
elements are all vital elements in the health and growth of the plants
growing in the system.
This
course aims to develop a solid grounding in the principles of soil-less
cultivation of plants in a home hydroponics situation.
