I run between 20 and 30 hives on the Florida/Alabama line. I use screened bottom boards, but I would not have any issue using solids either. I prefer screened because I like to monitor mite drop counts after OAV. Also, it just seems like it would be a little bit cooler for them on these 100F+ days we get down here. But that is probably helping my feelings more than theirs. They would be fine either way. Also, bees naturally work their way up in their hives. You can reverse the boxes if you would like, but that is not necessary.
Don't sweat the bottom boards. It is unimportant. They would do fine with solids, they would do fine with no bottom board and they will do fine with the screened bottom boards you have on them now. Just make sure they are queenright going into winter and that you have treated for mites and have them under control. Good luck.
