I dont have a Nep but im planning to get one next year. I have a question though. If your not suppose to do the tray method with Neps, for their roots will rot, then do you just water them overhead. And if so, you would have to get a pot with no holes, right? Or if you get a pot with holes, then the water would drip? Please fufill my question that has been in my head for a while.
