Lights vs PLant Sex

I wanted to clearify this for myself, i have a friend whos growing with his buddy using all feminized seeds and 1000W hps light. Once his timer got messed up during veg stage and the lights got switched off for 2-3 hours when they shouldnt have and my friend thinks that one his plant (out of approx 30) turned out to be hermaphrodite. Is that possible even if they are feminized seeds that is my question.

P.S: earlier this day i had a similar situation myself hence wondering.

it shouldnt, maybe in all those seeds he accidently got a hermi seed.

that happns its all in the seed

Yeah, You can get hermies off feminized seeds. Its a lowish chance but, you can cut off the banana's (earlyish sign of showing.) just not when they turn into sacks or you can stunt the plant. Peace out.

Also ive never heard of one day of stuffed up light schedual gives you hermies..

thanks alot guys
