I've read that stress during veg can cause a higher male ratio. I thought sex was already determined when the seed is made but I have read in several places that if it goes through higher stress during veg then it is supposedly more likely to turn male.

I also wounder if that is true when making the seeds themselves then. Like if the female making the seeds goes through stress while producing the seeds, even if they don't stress enough to herm, would it cause the progeny to have a higher male ratio? I'm curious about that one.
I had a well known breeder tell me that he thought that perfect germination conditions led to higher male ratios.
I personally believe it's genetic and predetermined.
I've done many chucks under fairly identical conditions and have even had crosses turn out, mostly female, accross the board.

Allele pairs are made at fertilization, it’s botany! No creature on earth spontaneously changes sex. We do know there are precarious intersex issues based on environmental conditions and just like math, people that don’t understand make up a theory, while believing it to be “unknown”. Pythagoras was burned at the stake for claiming you could define the world with mathematics! There’s some evidence that suggests that stressed mothers may produce a slightly higher male count, but it’s on the order of 10%-15%.

Useless fact but Clownfish can, they are all males at birth and the most dominate one when pairing up will change into a female.

I treat my seeds like gator eggs...

3. TEMPERATURE IS IMPORTANT.
Unlike all other reptiles, the temperature at which the eggs are incubated will determine the gender. When temperatures are below 82.4 degrees Fahrenheit, females result. Males typically incubate at above 91.4 degrees Fahrenheit—anything in between the two results in an even number of males and females.

Only time I have been able to say"damn that's a bunch of males"
Is when I popped seeds under (high output uv t-5s) them shits was cooking them seeds.every seed was male,could have been bad luck also..

Anyone have feedback on setting up an instagram site for genetics? Pros and cons, what to consider. Appreciate feedback from you chuckers

Now there is some evidence that suggests that stresses during pollination can increase male rates in progeny.
That's what I think is happening. It does make sense to me that stress during pollination could do that. This would also make sense with what some are saying too, that different people planting the same seeds all got high or low ratio's of males with certain strains. If different people grow them in different environments, the most common factor would be the conditions that the mother went through during the seeds production and could explain why certain strains have a higher ratio than others.

I forgot to include that a few other members here, have also had high male to female ratios, with seeds from my crosses of this male.
@ChronicWonders. How did the Copper Tops (Copper Chem x Goblins Gold) do in germ?
They germed fine and while I had a higher male to female ratio it wasn’t staggering. Winter Solstice I believe was the one I ran into an all male ensemble.

Getting an all male pack is like getting kicked in the nuts.
I wanted to do a open pollination of goji og but I only got 1 male in the 11 pack. I used him but his pollen wasn't very viable. Didn't get as many seeds as I had hoped.

Its all a game of percentages. Eventually if you pop enough you'll get closer to 50/50 ratio. But it sucks when you get short shafted.

isn't there some fish i think like a flounder or somthing that changes sex? i think so but not arguing lol.

I'm not sure if they are better or if they make more rare phenos popup.
Strain depending on the lanky/large node spacing.
Thanks for your thoughts. I guess it's hard to know by looking then if it's strain dep. Makes this very difficult to take advantage of for a small grower like me.

I guess if you're looking for a change from the normal within a strain then you look for recessiveness. But if your crossing strains that haven't been crossed before, you might not have to. Like if trying to recreate rks, for example. is that any sense?

P.S. my brain worked for once. Flounders change sex, based on temps. And groupers and halibut,,. Like all the weird ass looking fish haha. Even the clownfish has a ~ for a stripe.

The seeds i sprouted were during the warmest time of the year for my room. In the winter when it is cooler, I seem to always get more females than males. Really hard to prove though, if I pop more now...it would be the odds since I got mostly males last time. I would have liked to get more females, but the males told me enough.

ah bro science in motion!
I think the defining factor is within the phenomenon of hermaphroditism in cannabis. I mean by itself is a sort of sex change but it’s not a complete sex shift. Also when you reverse a flower it doesn’t reverse the whole plant ant if revegged it will return to its original sexual state. It’s not a genetic shift, it’s hormonal.
