This product is very cute and affordable, however they are extremely shallow and do not have enough depth for roots of the majority of my plants. The only thing they are working well for is small succulents and cacti that have shallow roots. Also, just because it is 4 inched doesn't mean the chain should be so short. Does not hang long enough for sun and viewing. I got jute rope from the dollar store and hung them with that instead so I could get the length I wanted.
