Removing Annuals from the Lights

[mobiledynamics]

Never really seeded annuals@home before. I need the light/shelf space for something else germinating. What ill effect would I have on a annual flower if I take it off the lights and put it by the window for a month .

It's been on the lights 16 hrs a day for almost 3 months...
As a test bed, I even took the same germinated seeds and put them by the window. The ones by the window are still the same size as when it sprouted (1st set of leaves 1/8" big post sprouting). Whereas the ones under lights are obviously leafy and bloomed. Still very small though. And this is a sunny window

Will I stunt the plant if it's not going to get light for 3 weeks or so.
It's too cold to put them out now but I just need the light shelf space for some other new things...

And or I be on 24 hr on call duty and rotate them on them shelves ;-)
