just bag, actually my first grow. so i have to admit that i went into the room a couple of times during the dark but i never turned the lights on i used a small black light for literally seconds at a time just to test the ph. will something like that effect my outcome or by light leaking in do you mean on a regular basis ( light that would turn plants to males)

I planted 12 bagseed, never interupted my 12/12 and i came out with 4 fems, so I think it mite just be the way it is.

I feel your pain. I have had 10 out of 14 that were male! It sucks but the way I look at it, "the law of averages" will kick in soon and I will be rollin in bud. The 4 females I got are very nice and I am 4 weeks from harvest. They were my last grow using bagseed gear.

I also just started a thread about this very thing...sorta. I was told today that not keeping the veg room in total uninterupted darkness for the dark time would cause this. I don't believe it but it has started me thinking a bit. My flower room never gets interupted and it is light proof. I am just saying...

Make sure your 100% sure if there male or female, sometimes people can mistake the sex very very easily.

Here's an example

i've found when i plant bag seed it is male more often than not. but this is not evidence - just my experience.

if its still early days of vegging dont be too hasty, apparently females do look like males in the early stages so after you think its male give it a week to see if they grow a hair or a dimple at the end of the ball like thing, also i read that males tend to show after 7-8 days and females more like 10-14, keep them far apart and so the pollen cant transfer, they shouldnt be able to pollenate the females untill about 3 weeks into the vegging, or so i read.. my first attemp too dude, out of 2 plants one looks to be male the others not showing, im giving the possible male another week.

Always plant at least 20 if you want 10 females and hope for the best or use clones only

"any kind of light during the dark period can cause them to turn male or even hermie."

I thought they could only go hermie? not male.
does anyone know for sure?

think they can only turn hermie, as seeds there sex will be chosen and they should have yy yy for female or something like that, but if they get shocked there gene setup could change to yy xy, male would be xx xx and xx yx if hermie.
think its something like that i might have the x's and y's mixed up but its an example.

everybody says to get rid of the hermie but if they have turned from a female to hermie apparently they can pollenate your other plants but the off spring cannot be male as the gene set up is still female, and the chances are more of the offspring would be female, some hermie. it isnt something ive tried but i did read quite alot about it, and my understanding of physics would lead me to believe its true.
