Kevin, just read the article about the 300 zone. Seems a long way to tote water. So just thinkin, a long piece of garden hose. Loooonnnnggg piece, or should I say several together. Gorrilla tape a funnel to the end. Take a piece of cord tie it in a tree high enough to let gravity take the water where you want it. Pour it in slowly. Might even set up another bucket with a small spigot to feed the hoses so you just keep feeding it with water instead of taking the water buckets out 300ft. lol, just a thought! But with a little trial and error could work. Not mechanized in any way.
