GrowFAQ : Hydroponic system
construction : Ebb and
flow

How do I make an ebb & flow hydroponic
system?

The goal: To demonstrate the
construction of an Ebb & Flow hydroponic system.

The system being constructed is small, however
the design is the same as larger systems.

Parts list...

Resturant bus tub, 15 1/2" x 20 1/2" x 4 1/2",
flood tray.

Resturant bus tub, 15 1/2" x 20 1/2" x 7",
reservoir.

Reservoir lid, 15 3/4" x 22".

Overflow fitting.

Fill/drain fitting.

Water pump, 70 gph.

Tubing, 1/2" ID.

Aquarium air pump.

Air stones.

Green air line.

Notice, in the pictures
above, the one inch holes, in the flood tray for the
overflow, and fill/drain fittings, also, the two inch
holes in the lid, for the fittings to pass through.

A view of the plumbed flood tray with lid. See
how it fits over the fittings.

This is a view of the reservoir with lid, and
plumbed flood tray.

Here, it's all assembled. The water and air
pumps are not shown. The power cord, and air lines fit
between, the reservoir and lid. A small notch may need
to be added, to avoid pinching the air lines, and to
help the flood tray sit level.

Assembled with six 5 1/2" square pots. Notice
the easy access to both fittings. The fill/drain
fitting has a connector for a 1/2" hose, under the
screen. Remove the screen, connect the hose, turn the
pump on, and pump out the nutrient solution. Makes
reservoir change outs very easy.

Another view of the system.

Note: Choosing a container...

Not all containers are made equal. Some are
very sturdy, while others are not. Using a weak
container will only lead to failure and a flood.
Choose heavy duty containers. Also, some containers
will need a center support to keep them level
under the weight of the nutrient solution.

Note: About sizes...

The
reservoir should be large enough, to hold two, to
three times the volume of the flood tray or table. The
pump should be sized to flood the tray in 5 min. or
less.
