I have a question about the light cycle. For now I have to put the lights on at night so the darktime would be from 10am to 4pm, but I when I turn them in to flower I want to switch it, so that the darktime would be from 10pm to 10am. To do this I have to keep the plants in dark for 24 hours. Is this going to cause problems?

The reason for this is that Im expecting maintenance to come to my apartment with in a month and I dont want them to see small light leaks from my closet and get too curious. They arent doing anything in the room where the grow is, but who knows what those nosy bastards will do if Im not home when they come. And also I dont want to wait that month to start my grow.
