Thanks to all of you guys here who bounced ideas around with me a few weeks ago concerning the best choices for watering some raised bed garden boxes. I settled on RainBird XPCN nozzles on 4" risers, and couldn't be happier with them. Like the RB propaganda says, they spray in a nearly perfect square. It's pretty remarkable to watch. The pressure compensation works as advertised, too. They spray just about exactly 4 feet left and right and 5'-8" diagonally. I did not fully appreciate another feature of the XPCN until I fired them up. They have two settings for the arc. One sprays up and reaches the maximum rating (4 feet). The other directs the spray much flatter and reduces the overall arc by a bit (around 3 feet). This will be perfect for those plants which prefer to not have their foliage wet. I have started a blog on my raised bed gardening project: Jeff's Garden Blog The first entry shows the boxes after I set and leveled them and the plumbing for the irrigation. I know there are at least a couple of Mac-addicts running around here. FYI, I used iWeb to produce the blog pages, and it worked like a champ.
