If you look at the Farmers and Tractors stores you will find mister and fogger nozzles that are interchageable. They fit into the end of the pipe and a ring tightens them into place. The smaller gph will produce more humidity, which is what you want I think, instead of a wetting of the plants. Most of the foggers use interchangeable parts. It is possible to customize the area, put foggers and misters where appropriate, and change if necessary. The last time I checked, when I put up my GH they were very reasonable in price. Dendrobium
