Driving North with Flowering Plant, extended darkness?

Ok, not the brightest idea to bring a plant 900 miles north a week and a half into flowering, but i've put so much time into this lil lady that I can't not get a toke. Its my first grow and this is the only one that survived of 4. Just found out its a female too! Pumped! Anyways, i'm planning on stressing it out a bit by keeping it in my cooler wrapped in a plastic bag, it will be bent over a bit to fit too. I figure its just like a bend technique with an unnussual amount of darkness. Anyone know how bad not giving it light for awhile in flowering stage is? Please post

What does common sense tell you to do?

messing around with a plant's (especially a female) lighting cycle during flowering can cause massive stress to the plant which in turn could cause it to turn into a hermaphrodite. if you dont know, a hermaphrodite will produce male and female reproductive organs/flowers (pollen balls, and stigmas respectively) and will self-pollinate... also know as "selfing",, this is a good way to go about preserving the exact genetics without having a male of the same strain.
during flowering the most recommended lighting cycle is 12 hours light 12 hours dark.
Light pollution can also cause hermaphroditic airy buds producing seeds. this occurs when light reaches the plants foliage during the dark hours
