@absolutus Do you have any vertical garden yourself?
This one has been a smooth ride so far.
Plants are protected from the weather (they have been grown by seed and there was a storm 2 days ago, no damage), they are watered from top without wasting time, and are draining one into the other.
Only problem is the fertility replenishment really, which I'm trying to turn into a bonding excuse =D
I'm building extra composting bins, I'll share the design once it's done.
