If you're going to build a hydroponics system, it's

best to begin with a container to use as a reservoir. For homemade
systems, it's best to use a fish tank or a similar object. Once you
find a suitable reservoir, you must paint it black. The black pain will
make your reservoir light proof, because if light enters the reservoir
it will promote the growth of algae. It is also a good idea to score a
line on your reservoir once it is painted (use a knife, and scratch off
paint in a straight line from top to bottom), which allows you to
monitor the amount of water in your reservoir. Some people may not have
to score their reservoir if they use a floater (Styrofoam), which
indicates the amount of water in the reservoir by sinking. However, the
line will give a view of the nutrient solution level.

Styrofoam
should be used in your homemade reservoir. Before installing the
Styrofoam into your reservoir, you should use a tape measure to measure
the reservoir, from inside of the reservoir from one end to the other.
Once your reservoir is measured, cut the Styrofoam 1/4" smaller than
the size of the reservoir. The Styrofoam should fit nicely into your
reservoir, and have enough room to adjust to changing water levels.
Making your own hydroponics system also requires you use net pots, and
you should cut holes in the Styrofoam for the placing of the net pots.
A hole should also be cut into one end of the Styrofoam to allow for
the airline to run into the reservoir.

When creating your own
hydroponics system, it is also important to consider how many plants
you want to grow. The amount of plants grown should depend on the size
of the garden you build and the types of crops grown. Plants should
also be space appropriately so each plant receives a generous amount of
light. It’s also important to choose a strong pump for your hydroponics
system. A strong pump should be able to provide enough oxygen to
sustain plants. It’s best to employ the help of a professional when
choosing a pump from a hydroponics supply store. Giving the
professionals information about the size of your reservoir should make
it easier for them to make a recommendation.

After installing a
pump attach an airline to the pump and attaching an air stone to the
other end of the line. It’s important to make sure your airline is long
enough to travel from the pump into the bottom of the reservoir. If the
airline is not this long, then it should float in the middle so oxygen
bubbles can get to the roots. The line should also be the right size of
the pump you choose, and most pumps come with the right size airline.
It’s advisable to use a one-gallon bottle to fill your reservoir, which
allows you to figure the capacity of your reservoir.

Lighting is
very important if you’re building a hydroponics system indoors. If the
system is inside, you’ll have to provide artificial lighting for your
plants to thrive. The size of the garden will determine how many light
fixtures and how many watts will be needed to provide proper light.
It’s a good idea to visit a lighting store, where you will be able to
receive more information on lights to use for your system. When plants
are in growth phase, they will need high intensity discharge lamps.
When plants are in bloom, high-pressure sodium lights increase yields
and will grow denser and heavier flowers. Using fluorescent lighting is
also an option, but fluorescent lights don’t offer the same amount of
lumens as the others. Fluorescent lights are better suited for starters
and seedlings and for growers with ventilation problems. Fluorescent
also burns cooler than other lights, which allows you to place your
plant closer to the light source without damaging them.
