I spent some time building a test platform for a hydroponic garden. All components used were stuff I had in the ‘workshop’ already, so it just cost me a few hours to build. Also bought some nutrients.
For now I am happy with the setup, I will keep it running for a few weeks to ensure the ‘test subject’ plants are happy, and then scale up the design to something more usefull.
A friend in high school (Koos Brits) told me about hydroponics in 1989 (if I remember correctly?). I did some research over the years but never got to the point of building a working system. Well, this is the beginning of a (another?) new hobby!
Here’s a pic of the test system:
