Ive had mixed success with the upside down planters I used last year but more success with one of those upside down garden thingys -

One good tip I read on the article above is that if you put plenty of vermiculite at the top of the bucket/planter then when you water it, the moisture will help stay around the deeper roots which are the drinking roots apparently - albeit they are inverted in this planter so are actually the shallower roots!
