Anyone know about Florida prisons?… (5 year sentence)

My man is in Washington county about to get sent off to whichever prison in florida, still not completely sure which one. Is there anything I need to know or anything I can do to help him while in there other than the typical money, calls, books, etc. He got 5 years for drug charges and he’s definitely not exactly new to being locked up, but I am new to this long of a sentence. I just want to be prepared and know that I did my due diligence in getting as much info as possible. Any pointers or anything at all to be supportive and knowledgeable would be greatly appreciated. thank you!
