Yes,I did that once.For me since then,is lights out is lights out.A shutdown of leaks,and continue to let them sleep like before.
They say you can use a green colored light so the plants cannot see,but finding the right green glass left me sketchy of the idea.
I would not breed with that pheno (not strain) unless you allready took clones and run them thru a light leak free flower/harvest.If the clones produces a truely exceptional bud with your technique/set up,and hermie free?I would keep her clone only.Keep in mind some gardens have a treasured dank that will throw sterile male flowers,and or spit out a seed or 2.If desperate reveg at 24 hrs till you see revegging,and bring down to 18/6 and let her recoupe.This is potentialy a months long process with no guarantees.
