Yesterday, TJ finished trimming out the grow bed and added additional PVC pipe.
I (Scott) decided to use untreated and unpainted 1″ x 4″ boards for the top trim of the grow bed. They will rot and need to be replaced in a few years, but I wanted to minimize the chemicals that would leach into the water from paint, stain, or lacquer when it rains. We also like the way it looks…for now at least.
The pipe is sloped from the fish tank to the other end of the grow bed. Small pieces of one-by-four were used as support for the pipe.
Here is the end of the pipe that will direct water into the grow bed from the fish tank. This photo also shows the nylon material that is used to hold the pipe to the grow bed trim.
I filled the grow bed with water today to make sure there were no leaks. We should be finishing the system very soon…hopefully tomorrow or Monday. More photos coming soon.
Yesterday we also celebrated my 47th birthday. My 3-year-old son decided that he wanted me to have a tilapia birthday cake. No, it wasn’t made of tilapia; it just had a picture of our tilapia on top. The fish in the bottom, left-hand corner of the cake is Bacon. I got that piece 🙂
