Here is a free design that I came up with for an ebb and flow hydroponic system. Since this isn’t the sort of thing that most people come to this site for, I posted it on the Instructables site.
It works well, and, using just a few plastic containers and some pea gravel, it is pretty easy to put together.

There’s a video too.
