sunlight for moonvines

[Paperwhite newbie]

I have had the flourescent light on the moonvine plants for quite a while, since they sprouted. Would it be a good idea to put it on the windowsill for a while? It is not real warm today, only about 27 degrees and not sunny, do you think that it is too cold for the moonvine plant in there? The Amaryllis plant has been in there since the flowers died and the leaves are really getting tall, it has not died so do you think that it will do ok?
