I disagree -- I think we DO know the effects of 24-hour light on crop
plants. We know this both from crops grown above the arctic circle,
where they get 24/7 sunlight during the summer, as well as from
experiments such as NASA's growth chambers, which do the same thing
with artificial light. And yes, it does increase crop yields
substantially.

You make a good point here.
