I have set up 2 of these vertical gardens side by side.  They provide privacy  between   2 patios in a condonimium.  The shelves of each unit had to be carved out to accommodate small pots.  The space was too narrow for even small pots and too deep for really tiny pots that just slid through.  But all in all I'm glad I bought it.  I like the fact that the neighbor can use the back side for her own pots, but I'll need to carve out the  shelves for her to use.  Because the pots are on a slant, each  pot has to be removed  for watering  to avoid the water spilling out -- but it's a very small inconvenience.  It is very pretty when the plants are set up in terra cotta pots.
