yes but outdoor marijuana plants can turn herm as well. generally speaking, you are probably fine. They are a fairly resilient plant and I feel they can take quite a bit of abuse. But...its happened before too. Not much you can do about it except just check em everyday.

hell...I just left a CFL on inside my flowering room for 3 hours last night. Didnt even notice it until I saw just a tiny bit of light peaking. Thank god I did notice it, it might have run all night!!!
