I wrote in my book that one way to do hydroponics was to use a substrate like coco coir and growstones in a self-watering planter, and feed it hydroponic nutes. But I'd never done a particularly careful experiment on that point. But I thought it would make a neat product alternative to the splashers - no daily attention.
