If you are looking for a ways on how to build a hydroponic system then you have come to the right place. There are a few things you will need such as a sharp knife, a reservoir that is the same in height that it is in width, a piece of Styrofoam that is larger than the reservoir (this can be cut to size later).
When doing this project with your child you should always make sure to keep a close eye on them especially if they are using a knife or scissors. If it is an older child then it might be safe to allow them to use a knife that is not so sharp (such as a butter knife) for the children who want to do it themselves.
You will need to paint the reservoir black and this can be done with black spray paint. You will only need to paint the outside of the reservoir unless you plan on using it for something else again. In case it is a fish tank that you want to use again you should only cover it with a black plastic bag.
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.
You should cut the Styrofoam to fit the reservoir almost perfectly. You should cut it to where it will be able to move around freely as the water level goes up and down. For instance you should leave about an inch or an inch and a half in between the walls of the reservoir and your Styrofoam.
depending on the size of your reservoir you can grow many plants if you have a big reservoir. However if you do not have a large reservoir then you will not be able to grow a lot of plants at one time. You should try to find the biggest reservoir you can if you are wanting to grow a large amount of plants at one time. - 33393
