basic self watering container question
When I buy commercial self watering pots, it is simply some kind of plastic tray/grid that allows water to drain and collect in a space the bottom.
When I see home-made earthboxes and such, people seem to use pond filter-like water reservoirs or wicking tubes. Why? Can't you just for example, drill a bunch of holes into the bottom of gallon bucket and put it inside another 5 gallon bucket? Won't the water wick through the holes just as well as a wicking tube/pond filter?
