I personally am not all that convinced that the holes in the buckets do anything. Assuming most of the root is at the bottom (seeking water) I like to think the aeration at the bottom at least helps with root pruning, if nothing else. Since sometimes I don't get around to covering the tops like this year, the holes at the bottom will help with drainage if there is a big storm.
