We are caring for our poinsettias and covering them for over 12 hrs. each night. We will be away for a few days in Oct. Should we leave the plants covered or uncovered?

I am not really sure which would be more effective, but I suspect leaving the plants in the dark for a few days would be more helpful for promoting flowering. The plants may be slightly unhappy because of the lack of light, but they'll recover within a few days.
