I'm tired of dragging hoses around the garden so am looking for a type of irrigation system that meets the following criteria: -simple -inexpensive -will work w/ pressurized municipal water -automatic would be a big plus as we're often times out of town on the weekends I don't want to spend the time/money on anything too elaborate as we will be moving in the next 2-3 yrs (saving our pennies/energy to build a new place). It doesn't have to be pretty either. Just functional! My background is in gravity irrigation (large farm scale) and the ol' hose dragging sprinkler placement method (small yard scale). I have little idea of design methods or available parts for more sophisticated sprinkler systems for family sized gardens. My beds are mostly of the keyhole variety and I'm envisioning a combination of drip and sprinkler heads. Would love to see some illustrations or actual pics of varying systems. Any ideas? Thanks!
