Welcome back. I was wondering with the cost of maintaining it, is it possible to make money with just a cube? I'm new here so I don't know how you did things before. Or are you just doing it because you like it and sell stuff just to offset the costs? Either way welcome back again and can't wait to see what you come up with.
BTW I have a new plant that I love, alternanthera reineckii cardinalis, there seems to be a expensive mini version that has been talked about a lot lately. You might want to look into that.
