I purchased this to keep my hardy succulents in during our wet weather (fall, winter and spring).  While the shelves are constructed of a wire that wasn't very good for individual pots, that problem was easily solved with a piece of the cardboard box that the rack came in.  It was easy to construct and worked perfectly in the big rain storms we've had this week.  I can keep my plants from getting soggy feet while they are still able to get the sunlight they need.  The 'door' opens easily to keep the humidty from building up - It's perfect for the purpose I purchased it for.
