I'm on the west coast, but approx the same latitude as you are. Out here if you want to grow a faster good producing strain it seems that all the 'big boys' go with blue dream. It is a fairly mold resistant hardy plant that doesn't mind the hot days. I have seen them over 10 ft. tall but with proper training they can be kept lower.
Bubba Kush is also a 'cash croppers' favorite, as it to is a faster flowering plant. Although I havent personally tryed either growing or smoking it.
I had very good success with Pure Power Plant by Nirvana. I grew it for several years befor I got tired of it. Should have kept the strain going in retrospect as it out produced many of the ones I replaced it with. Easy to grow and maintain.
Several other of the Kushes seem to do well. OG Kush is always a favorite and in my experience growing it I did quite well. I harvested in mid to late Oct. Over a lb and a half per plant easy. ( Planted in the ground )
If your tastes lean more toward a Sativa than C99 is a hard one to beat. 54 day flowering time and a very nice daytime smoke.
Blueberry is also a local favorite, although I haven't had any experience with it so I can't attest to how it grows.
Ones that I am looking at for next year.
Critical by Royal Queen - very short flowering time
Tahoe Bubba Kush - A local favorite
Chemdog 91 - Cali Connection
Blueberry - Not sure of the breeder
I'm also only interested in quick finishers, as the weather can turn nasty in Nov where I am. I lost several plants this year because I didn't do my homework on how quicky they finish out and paid for my lazyness in moldy bud and rain wipped plants.
Hope this helps
