The problem that the residents 'gotten dirty with' under me when plants change I see at all, because the boxes can be any time so back up take. If poured too much, it may well happen that some water drips, but that's a fundamental problem with all window boxes. I have been cast with 1 liter (per vessel) without it dripping.
Especially chic it looks when choosing plants that hang over the edge.
My delivery was unfortunately defective box 1, but for a nice short email exchange I got immediately free a new box sent!
I can not any of the boxes with the ghastly 08/15 brackets like highly recommend these window boxes!
