I keep a pretty close eye on my wall . . . not because I’m worried but because I’m fascinated, enchanted, in wonder. The process of plants not needing soil or watering is such a cool concept I’m still in awe.
I’ve got a strip of felt that runs from the wall drain into the aquarium. This filter does a couple things. It provides a path for the water running into the aquarium and it keeps the PH moderating oyster shell from washing out of the gutter.
Yesterday I noticed a seedling has gotten a start in my drain filter. How amusing is that?! I have no idea what it is or what I’m going to do about it. It’s possible the roots would eventually block the drain which would be bad, but that’s the only reason I can see to remove the plant. For now I’ll watch and learn.
