We will probably have a lunch meeting in Vidalia. I would like this meeting to be an update for both agents and growers. It is difficult to work with young people and hold their attention particularly when you have to compete with television and video games. This can be particularly hard when trying to teach them about plant growth. While at the Plasticulture congress, I learned about non-circulating hydroponic systems.
Most hydroponic systems have some type of circulating system.
This helps aerate the solution so the roots can respire. Non-recirculating systems rely on keeping a portion of the roots out of the nutrient solution. The plants are suspended above the solution so that a portion the roots remain out of the solution. This facilitates respiration. The Styrofoam insulation is prepared by cutting 2 or 3 holes in the Styrofoam insulation such that the cups or oasis cubes will fit snuggly.
