might be ok, you might see some stretching, and to be honest the plants might suffer some as they are not getting the light they need but no way of knowing for sure till it happens.
Basically there are 2 types of chlorophyll, one uses the cool blue and one uses the warm red spectrum. If you can't get any for a week then throw it on a window ledge for some of the day to supplement the growing. Just make sure security isn't an issue.
