Not much experience with dew catchers, but fog interception and dew collect is something that has peeked my interest too. The down sides that I have heard for dew catchers are; they need to be cleaned and maintained, they are not very available and take up a lot of space. Redwoods are great at intercepting fog, up to 30% of their
water comes from fog. It is hard to find info on the interception rate of other plants. Also piling rocks around plants has been used to catch dew for ages. Share picture and results when you have them!
