To be used for watering the greenhouse! This way I don’t need to constantly disconnect the hose from the irrigation system. Also rain water may be better for the plants than well water, I don’t know. This is only the first rendition and I plan to upgrade this in the future when I find a way to improve the funneling of water. A diverter is in-line to keep the large leaves and such out and a mesh net at the cap to keep even finer materials out.
