I have used this method on dozens of grows. It works. You just have to watch out for stuff growing on your wicks. I use h2o2 to sanitize them. Right now the nutrients are in the bottom of a elevated saucer the ropes are lying in it. Eventuality there will be a bubble resivoir under them. Very low maintain eye and you use a minimal amount of nutrients.That's a neat idea. I'm definitely curious to see how it works for you. I have not come across that yet.
