black light question?

i been growing my plants for about month now, one is at about 9" the other is at about 11".This is my first time growing so i decided it would be best to start out small an grow outdoors.I still can't tell if there males or females, i believe i have one male/one female,but still not sure just yet. My question is, would it be alright to use a blacklight on them at night time? for like 8-9 hours when i goto bed.( my brother told me it will help them grow stronger, but my brothers been known to lie about alot of shit an i dont want to take the risk killing them if i'm not sure) also someone else on a nother forum told me that it would turn my plants purple. Anyways i'm just looking for some facts, so if you have any information that could help me out, I would surely appreciate it.

also are bananas peals an egg shells good for nutrients? would it be alright if i mixed them up in the soil?





im going to take some more pics later, the ones above i took at around 11pm at night about week ago.

found my answer, just happpen to scroll down after i was done with my thread an found a similar thread about blacklights. i guess a blacklight is out of the question remine me to hit my brother in the gut. still any information you guys got i would appreciate it very much.Thanks .i'm sure i'll still have alot more questions in the future, maybe next time i'll just do alittle bit of searching around on old threads before i ask my question
