James it looks like you had a great year, now you just have to figure out what to do with all of your bud, congrats.
PoDunk you should be fine. These obviously aren't the best growing conditions, but let them go as long as they can and just wait until you have no choice but to chop. I've seen plants make it into mid November in Michigan.
I have one plant still going. It needs until Halloween. My la cheese that was outside was my biggest plant weighing in at just over 26 ozs dry. It is also my best quality bud, that has never happened before for me so I feel really lucky. Here is a pic of my last plant standing, I think it is going to weigh even more than the cheese. It is my only fruity smelling plant, all the others that I've picked have smell skunky. The plant was ripped into four pieces last week and I had to tie it back together, I hope it makes it these last couple of weeks. I may pick it tomorrow if it looks unhealthy.
