If the plant's dark cycle is interupted even momentarily it affects the plant's ability to flower. QUOTE]
this is wrong, momentary exposure to light in the dark period( as long as it is very brief), the plant will not notice, it is when you have a light leak through all the dark period that it stats to cause problems.
remember the moon is out at night reflecting light onto plants in "dark period"
do they all stress and die?? there would be no plants at all if that were true.
Just repeating what I've read but I guess the article I got that from was mistaken. Of course I can't find the article now to show you guys. I agree that if a plant is grown outdoors then the moonlight wouldn't cause problems but if you stuck a plant that is used to complete darkness (ie, in a room or closet) out in the moonlight, I believe that would cause problems, Just my opinion. Below is a Q & A from Ed Rosenthal's website regarding light exposure and bud formation:
Q: One night during the second week of flowering my buds were exposed to a very strong flashlight. I also have a greenhouse and suspect that the buds are exposed to light from headlights coming from the road, about 30 feet away. Ive noticed that the buds start to tower, and the production of hair is reduced. Is it possible for these buds to fill in?
Do you think the effects are from the single flashlight exposure or from the headlights?

Ed: A single flashlight experience, even in the important formative stages of the second week, will have little effect on bud development. If the buds are growing thinner and longer than usual then the headlights are the culprits.
