CFL bagseed Light Problems.

Hey guys im on my 4th week of flowering and somthing unexpected has come up where my plants are growing. They are looking very good i have 2, and they are about 2 1/2 ft tall. The power has been shut off in the house that the plants are in due to the fact of a family member dying. I havent been able to get over there because the house is locked up. Therfore my plants have been in totaly darkness for over 48 hours. Will this stunt the plants growth? Will they still flower correctly if i get them back on the light schedule. Will they even be worth keeping? If someone could let me know on some information that would be great.
