Many plant species do change sex during their life span but so far I haven’t found info that gives a definite yay or nay for cannabis. And seed producing plants lock in sex at the seed making stage unless cannabis is an exception. Seems like something research would’ve picked up by now?

LOL Most studied plant in history and I still know fuck all. I guess scientific studies on stressing cannabis for high grade dank is hard to fund properly LOL All my research goes up in flames. I must stop using rolling papers for my journals. It would be interesting to side by side a germ chamber to manipulate temps. seeds are variable and ya can’t do it with clones but it would be interesting with a large sampling…hard to eliminate randomness with seeds though…

Worst I’ve ever gotten was 11 males out of 13, and one of the two females hermied.
Quick question; if females are xx and males xy, wouldn’t Mendelian genetics say we should get 75% females on average? Shouldn’t that be true for humans too? Damn I must still be tired because the evidence clearly contradicts my line of thinking

I think Bodhi had mentioned lower temps and higher humidity had shown to bring out more females… i may be way off here… @Funkjunky …?

That echo’s what I have read over the years
Yeah, hopefully as it becomes a larger part of agriculture, more studies will be done on it. Unlock some more secrets or just confirm some of the things being done in grows.

What does this tell about feminized seeds?
If the environment influences that a plant expresses itself as female while genetically it is not, what happens if that plant is used to create feminized seeds?
Food for thought.

Here’s a current thread going similar to this stuff, https://www.icmag.com/ic/showthread.php?t=376785&page=61
I’m trying to follow it but getting very confused trying to understand both points of view, I think they both have good merits and could be more interrelated than expected because of the fluidity of the plants sex.

I’m working on a killer cherry phenos of shiva right now . Straight cherry Eucalyptus gas once my labeling is done I’ll send a prez . Hoping for a late spring 2021 release.
Take care brother and be safe out there

I read an older article that people had gotten straight up males in “female” seeds, hence the change to feminized. I believe that was before the use of silver, using stress or over maturing a female plant to hermi and produce “female pollen”. The seed company attributed it to environmental factors. Then there’s another article describing how to get mostly females out of regular seeds by tuning the environment. I don’t know how much I buy into it, but it’s things that have been brought up in the past without any solid science. I can understand the conditions effecting the gender of the seeds while they are being made/maturing, but I think the gender of the plant is determined in the seed, with various levels of hermaphroditism in the genes that can be active or need to be triggered.

We’re really wading deep here into bro-science territory. We need evidence to corroborate that, otherwise it’s pure conjecture.
There are companies selling kits that can tell a plants sex from the cotyledons. There are some plants that get labeled inconclusive though, so it’s possible that some don’t quite fit the standards.
But.
We should all be able to agree genes are not controlled by environmental factors.

TRUE STATEMENT!!

I fully agree and it is basically all bro science. What always stood out to me where a few strains where people consistently got very high numbers of females, I can’t understand why but I find it very interesting as they aren’t feminised strains.

I like the idea of the sexual fluidity thing because it fits into the whole idea, basically the plant is a stable hermie more often than we realize and this is what allows it to have swings in the population depending on environmental facors. But this is my bro scientific standpoint at this point. Trying to figure out exactly what people want true males for or even how to identify them, that shit is beyond me.

I also used to believe the environment was influential in determining sex. However after reading seemingly hundreds, if not thousands of threads on various forums, the impression I got was that sex is predetermined in seed. Not the growers or breeders vault, just the luck of the draw. It is just always really hard to believe that it happened to you when you get a load of dudes.

Most females are not xx. Most are actually xy, containing the herm gene somewhere, although can be stable. XX females are females which wont herm, even under heinous stress. XX (pure females) happen approximately in 1 in a 1000 females. They are what breeders looking to make fems look for. They employ chems (silver, gibberilic, etc) to reverse the xx female. That pollen is used on clones of the xx female to create fems

hey guys, thanks for all the input. I hope i remember all questions:
it was a regular pack of des*tar bx by dynasty purchased at sannie’s when it came out. I put 5 seeds to germinate and got 4 females and the male. with male pollen I dusted the above mentioned cuts. since then the seeds spend their time in th fridge with many others. through out the time since making the seeds I grew several always male.
I grew different crosses with all those cuts but those made with the des*tar male turn out to have those high male ratio. other crosses are ‘normal’ like around 60-70% female. a friend just recently tried two crosses and all came out male.
my environments changes with the seasons but not to bad conditions. I mean its a bit dry in that room but that doesn’t disturb other strains (all kinds - purchased, pollen chucks, bagseed and so on) I really believe it’s the male and what he gave to the females.
I read somewhere that it’s possible to get higher female ratio by putting seeds in a bag with a ripe Apple and close it for some days. the ripening gas is responsible, I forgot the name though, ethylene or something like that.
I think maybe I’ll do a 12/12 run in solocups with 25 seeds or so just to see if it was just bad luck within this tries.
i appreciate all the discussion!
