Green light

My girlfriend and I have our flowering space in our walk-in closet. She needs to go in there to get shirts and shoes, and most of the time, the lights are off. Would it be possible to use a green incandescent bulb to illuminate the closet without affecting the dark cycle?

Yes. Plant light cycles are unaffected by green light. You can use it as a safety light in the grow room during the dark period. Plants use red and infrared light spectrums to measure dark period.
