Ya, we gotta get some answers over here.I tried a couple different kinds of rope, seeing which could wick water with food coloring up quickest from the bottom of a glass. Out of those, the winner was 3/16" braided polyester clothesline, "Blue Hawk 0.1875-in x 50-ft Braided Polyester Rope" from Lowe's, which also alluded to "gardening" use on the label. $5 for 50 feet. Other kinds of rope probably also work really well, but it's worth further experimenting. View attachment 4782128
So are you using this wicking method with soil and just adding water to the bottom of the catch tray?
