seriously this is not an accurate way to determine sex.

I don't think so either, but it'll be a fun test to amuse next time I germinate. I'd have to be pretty damn sure of the process before I'd chuck a seed because the shape suggested that it was male. Reminds me of measuring a person's skull to determine if they're a criminal.

Couldnt find what you got out of the White Widow. Im doing a fem grow from WW from nirvana and last night I found what appeared to be a ball but it was literally growing off a branch in between nodes/bud site/leaves. I mean literally just a bare branch with a wierd ball. Any thoughts?

Dave I've had balls on a set of female plants once, instead of bananas (staminate flowers). I had 4 female blueberry from an F2 pollen chucker and every one hermied, but no bananas - at the level on the plant when I switched to 12/12 there were female flowers below and bunches of balls above. Bizare.
Are you getting single balls or bunches? Using a magnifiying glass can you see a ball-on-a-stick at the node?

Hey sorry for the delay, but I literally found one ball that was in a really odd place. It was in between nodes. It was like it just popped out of a stem. It was a good inch from any leaf or flower, but Im sure it wasnt a bug or anything like that. Im almost a week into 12/12. Will a hermie produce pollen saks or no?

Dave I wouldn't worry about the single ball - it sound like an anomaly. Leave the ball for observation, to see if you start getting bananas, and check over the plant regularly. How many nodes is the plant now? Only one ball? Hanging or sticking straight out on a short "stick" (ball on stick).
"It was in between nodes. It was like it just popped out of a stem"
That does sound weird, not a normal hermie.
If you get bananas popping from the ball pluck the whole bunch and check the rest of the plant regularly. I haven't heard too many complaints about Nirvana's fems, but it is Nirvana and you could be getting an S1 from F2 parents, I found nothing on their site about WW genetics other than "Hybrid".
It's always a good idea to have a bottle of Dutch Master's Reverse and Penetrator on hand.

I have dutch master liquid light and penetrator. The ball was not on a stick either but when I removed it I squeed it and 4 little points popped out it was kinda wierd. What will the reverse do from dutch master and thanks for the replies

"What will the reverse do from dutch master and thanks for the replies"
Basically it is suppose to stop the development of current male flowers and stop the growth of new male flowers, on a hermaphrodite. I've had mixed results and find it works best if you hit the plant with Reverse and Penetrator at the first banana. I've used it on hydro clones (leaves and roots) during the first 2 weeks of 12/12 and stopped a clone from a bad hermieing mother, from hermieing.
I'm going to be lazy and work on my copy and paste
.
"Reverse will stop male flowers and hermaphrodites in problematic plants such as pumpkins, watermelons and any flowering crop that has a tendency to hermaphrodite or show male flowers. Dutch Master Reverse has a fast knowckdown action against existing male flowers as well as previnting more male flowers from forming due to their unique technology.
Reverse can detune the plant receptor cells that are responsible for gibberellin reception and secondary biosynthesis that is responsible for over 95% of the cases of unwanted male flower expression."

Dutch Passion feminized seed info:
In an experiment done in 1999 we grew 15 varieties of "feminized" seeds. We started with 30 seeds per variety. The goals were:
1) to determine the percentages of female, male, and hermaphroditic plants.
2) to compare the uniformity (homogeneity) among plants from "feminized" seeds with those grown from "regular" seeds.
1. The results were excellent. Nine out of fifteen varieties had 100% female offspring. Percentages of female plants from the other 6 varieties were between 80 and 90%. These plants were all hermaphrodites, producing their male flowers at the end of their lifecycle. Seed-setting hardly took place. No males were found.
2. Approximately 70% of the plants of varieties grown from "feminized" seeds were far more uniform than plants grown from "regular" seeds of the same variety. About 20% of the varieties were a little more uniform, while in 10% of the varieties no difference in uniformity was seen.
From literature and our own findings it appears that the growth of a male or female plant from seed, except for the predisposition in the gender chromosomes, also depends on various environmental factors.
The environmental factors that influence gender are:
It is important to start these changes at the three-pairs-of-leaves stage and continue for two or three weeks, before reverting to standard conditions.
To produce our feminized seeds, we start with selected female clones. Under standard conditions these female clones do not produce any male flowers. By the method we found, we are able to have these female clones produce abundant male flowers and pollen (see photos). The pollen thus produced we use for the production of our "feminized" seeds.

wait so are they using chemicals to produce fems which is the proper way or simply enviromental influences(stress)?

They probably keep their secrets close to the chest, an advantage over competition. They don't say the method of producing male flowers but I'd suspect it is an added chemical (like colloidal silver) or a hormone, combined with adjusting environment according to the findings they listed. And probably one or two they didn't list, conspiracies everywhere!

I have GreenHouse Super Lemon Haze Feminised Seeds, i will let u kno how they go, its a shame to think i got the shits with Hermaphrodites so i decided to buy fem seeds - if only i had known this then!
I am 8 weeks in2 veg and will be turning in 2 weels. So -Watch This Space-

Ninja most people grow fine with feminized seeds, and Greenhouse has reviewed very well for sexual stability in it's fem strains. Most likely you'll have no problem at all, just be prepared with some Reverse and Penetrator for the worst outcome.
How many weeks in flower 12/12 does your calendar system translate to?

Interesting thread hobbes. I grew Nirvana fem snow white my first grow a few years ago. Totally stable females. Great genetics.
Since then, I've actualy had more hermie issues with non fem seeds. Mandala Satori hemied on me real bad, was it something I did wrong? IDK! But I've grown Cheese from clone and Black Dominia in the same environment without any hermie problems, so I have to think the Satori was a bit unstable and they weren't even fem seeds.
I'm just in week 2 of growing GH Trainwreck, Super Silver Haze and BB Blue Cheese, all fem seeds. I'll let you know how stable they are for me. I can't be doing with unstable genetics in my grow room though man!
