Ha! I need far longer than 30-second naps when I'm at work!!
Steve, I have some mangroves in my sump and I mist them 2 or 3 times a day. They seem to grow quite well for me this way. I was kind of curious if there was a method I could use to automate this process. I could use a simple digital timer, a 12V windshield washer pump on a RO reservoir, and a dripline mist nozzle thing and thus have the plants "rained" on but I worry that even with a small pump like a windshield washer pump that I'd be spraying too much fresh water into my sump if this went on for a full minute. I'd prefer a smaller interval like 10-30 seconds or so.
