I don't have the cage set-up yet, but I was anticipating some sort of issues with drainage from the plant and was wondering what other people have come up with.
i see well the hydroton balls will only increase drainage. from what ive seen most cages have a drainage pan under the cage which is how im going to set mine up and seems to be the easiest maintenance.
My plants seem fine. I only ever water the hanging plants that don't get very much water from misting (they don't leak much water.) I drilled about 5 holes in the bottom of the cage and put a catch bin under it for the water from the dripper. Misting only doesn't leave much water in the catch bin though...
