Simple Ebb and Flow Hydroponic System

Step 4 Adding a Water Shield

Here you can see that I have attached a piece of plastic siding below the overflow holes. This was done to keep the water from flowing underneath of the plastic container and missing the water reservoir.

The plastic is held on with hot glue. You can see from the picture that I made a mess of it. I didn't think to do this until after I put in the pea gravel, and it was hard to get the containers far enough apart for the hot glue gun to fit in between.

You can also see why I recommended buying the special spray paint for plastic instead of just using house paint. It is starting to peel off. Of course, it has been on there for almost four years now, so it does last for awhile.

You might be able to skip this step if you angle the containers downward more than I did. I probably didn't think this part through enough, but it works. : )

Try experimenting to see what works best.
