I'm 5b and have been challenged with autos during the summer (I grow them in the winter under lights).
I live in Northern Michigan and been growing outside for years. We have a very short season that can and will get wet and cold fast. You need to be done by the end of September. If your not flowering by the end of July your not going to make it. You need almost a 100% Indica or one that's a least 80% Indica dominate. I start mine inside about the middle of April. I move them outside around June 14th only if the wheater forecast is good. If you put them out before than your asking for trouble here. Some of the strains that I found that would make it are Grape Ape, Afghani, Purple Kush, Hindu Kush, etc. It gets wet and cold here there will always be mold problems. You need to be on top of your pruning giving the bottom of plants alot of air flow. Again for Michigan outside there is only one way to go heavy Indica dominate or 100% Indica. Good luck and have fun!
There is a thread going in another one of the forums on this message board for those of us in Michigan. It is just a way to say hello to each other. The link below will take you right there if you are interested.
