Hey Brad,
I don't put mine down into brumation until mid November, but that's partially because I am dependent on cooler weather outside for this to work. I put my adults in the basement of the house and it really doesn't get cold enough until Dec for a good brumation.
I only put the adults into brumation and try to keep the juvies up to keep feeding them. However, I know several people that just brumate their entire collection so that part's really up to you.
Where do you live? The only way you'll be able to brumate sooner than winter is by having a good temp controlled room in your house with a window AC unit or wine cooler or something where you can manipulate consistently cool temps.
Good luck!
Dave
PS with respect to peublans, I have brumated them in a spare bedroom closet before with temps only getting as low as the low 60s and got a good clutch from them.
