If you are wondering how to build a hydroponic system then this is the right article to read. There are only a small amount of things that you will need to build this system and it will allow you to get your hydroponics system up and running in no time

The things you will need are an external pump, an air line, air stones, a water proof bin, a bucket, a fish tank for use as a reservoir, Styrofoam, mesh pots, grow rocks, grow formula such as rose food, a sharp knife or a box cutter will do. If you have a clear reservoir then you will also need black spray paint to paint it.

This is not a job for a child unless they are under close adult supervision. If you are looking to reuse the fish tank you should cover it with a black plastic bag instead. If you allow light to enter the fish tank then this will allow algae to grow. This is something that you do not want to happen.

Make sure if you are doing this with your child that you supervise them closely because at some point and time you will have to use a sharp knife to cut out the Styrofoam to fit in your reservoir.

Always make sure that the Styrofoam is about two or four inches smaller than the reservoir. Do not put Styrofoam in the reservoir immediately. Put the net pods on the Styrofoam where you want the plants to be placed. Trace around the bottom of the pots and cut the circles out. Make sure that the Styrofoam fits nicely in the reservoir.

Depending on how big your reservoir is you can plant and grow a large amount of seedlings. IF you want a smaller reservoir then you will only be able to plant a few seedlings at a time. If a child is doing this project they should probably start with something small because they might only be disappointed if they can not keep their seedlings alive.
