moving during flowering

Hi so my grandparents and coming to visit and they are quite conservative so I decided that it would be easiest just to put the plants away for a few hours in hopes of avoiding an excruciatingly judgmental conversation with them about growing cannabis. My plants are currently in Flower, about the 4th day and I have moved them into a closet with minimal lights. because I just can't move my whole set up from my Grow-Office into a closet. It should only be for 3-4 hours. Do you think it will cause any problems for them?

They have one 42w and two 27w CFLs in the middle of the 4 of them.

Shouldn't be a problem, just understand that growth will not be what you're used to.
