how do you make a hydroponic system using a rubbermaid container?
I am looking for a manufacturer who produces a 1/2 inch rubber (bulkhead) grommet seal to insert a plastic barb fitting into a plastic water container. I am trying to make a dutch bucket hydroponic system and need this grommet for the nutrient flow lines. Larry Try www.aquaticeco.com they have a good selections of bulkheads.
