Paint & hyroponics
I have an outdoor hydroponics garden consisting of over 120 white homemade bato buckets (5 gal buckets) where I grow vegetables using wood chips along with pvc piping and a Rubbermaid reservoir. Last summer I had a big problem with algae clogging my drippers. I was told that I should either paint or cover my piping, reservoir and buckets in order to discourage the algae growth. I really don't think covering them with foil is the way to go. Then again if I paint them on the outside is there a concern with the paint leaching into the nutrient solution? Do you folks have any suggestions? Should I paint them black and then coat them with white to keep the heat level down? What type of paint should I use? Thanks.
