Sleepy plants in day extension

[Rasterman]

Both my indoor grow areas are on flowering schedules, so I bring these plants in at night under a regular old room ceiling light. Some of them start acting like they're going to sleep 30 minutes or so later by getting all wilty. I know conventional wisdom says they won't go into flower, but might they?

Shouldn't they be trying to get all the light they can? Inquiring minds want to know...

I've been doing this for a week or so...
