Well i have 24 hr veggies in same closet with 12/12. The plants are 3-4 weeks into flowering, but don't get COMPLETE darkness. But you are just hardly able to make out hairs on buds at 6-8 inches, and when i look at the middle of the plant (without white wall background) i cannot tell that there are individual leaves. How sensitive are plants to this? it is like a bright moonlight i guess. Could these plants become hermaphrodites?
