Jungle respawn times?

So what specifically is your question?

If you want to know the respawn time on jungle monsters, it's 1:40 for small camps, 5:00 for buffs, 6:00 for drags, and 7:00 for barons. (all in minutes:seconds)

If you are wondering why you can not always see the timers on camps when you press tab, it is because you don't get a timer on a camp if you don't have vision of the camp when it goes down.

Hope that helps, and if not, feel free to ask more specifically. :)
