3 months of pure sunlight kind of tells me that you'll have a 3 month vegitation cycle, I would imagine that when you get to having some dark days the temps drop off pretty severe....does it drop below freezing or will you have up to 2 -3 months before it does?

You may just want to consider staying indoors...hell, Alaska is our most reasonable state concerning growing in your house....take advantage of it!

Good luck on the grow!:thumbsup:
