benrhx- there are many great plants that would suit you just fine. look for companies that are known for outdoor varieties especially canadian ones. stay away from dutch seed companies for outdoor plants. i have wasted wads of cash trying overly hyped dutch, overpriced plants that are only suited for indoor cultivation no matter what they tell you.
a good heavy indica will suit you fine. look into canadian companies like east island, west coast seeds, next generation and kooteney mtn. they do not advertise much and will not have the uniformity an expensive variety will have but they are made for the outdoors and will be great ganja if grown well. when i first began growing mighty mite crosses, mendocino madness (thseeds) dutch treat (east island) and afgani crosses were some of my first successes. you can still find them for sale and for quite cheap. timewarp, ultimate indica, burmese kush have done well for me in the past years as well.
i must be able to harvest no later than oct 10th where i am at, earlier if possible.
someone said endless sky i grew endless sky about 3 years back and it was incredible a perfect plant but i also did here some people were getting bad batches. doc.greenthumb has many good outdoor varieties but expensive if it is your first time growing i would buy several cheaper kinds rather than one expensive one.
autoflowering plants may be all the rage right now but you will never get great hauls like you will from 6'-7' late sept monsters. iranian auto from doc get big but 5-6 ozs is a huge one and they are finiky to grow if it is your first outdoor grow.
