Question Male/Female ratios

[GthaEnigma]

I have to ask...is anyone else having crazy #s of males in their seed starts? I pulled 5 females from 38 seeds across several strains. Is it just my bad luck?

The science of cannabis has come a long way in 40 yrs!

 

[jaguarlax]

I read this in a growers book 40 yrs ago. I grew 4 Greenpoint regs three yrs ago, all were fems.

Can you wrap your mind around another fact?

Benzothiadiazole, gibberellic acid, silver thiosulphate, silver nitrate, and colloidal silver can be used to alter genetics also.

I post facts , Im not the guy that bullshits others or takes and alters photography for fucking points on a forum.

Hows that? You pissed me off.

The gay emoticons reveal your intellect I guess.



I answered a question you could not. That's ALSO a fact.

And I asked a question. What makes it a fact? Because a book says so? Sorry you are so easily peeved... I also clearly understand the fact that stress (coillodial silver) can cause a hormonal response, but that is not altering genetic code... that’s stressing a particular part of a plant into creating seeds.... the entire plants sex doesn’t change. Anyone else have an answer to my question? That was just.... like a question?

Thank you brother.... this creates even more questions lulz... but I think I’m gonna keep them to myself because my emoticons are clearly triggering folks this morning.

This makes a lot more sense to me than a book telling me my spectrum of light is going to influence my male/female ratios.... and I wasn’t asking about stressing it to produce seeds or anthems... I was asking about a female plant with only female chromosomes can change its sex during germination.

I don't know how I know but there is male or female from seed both can show intersex traits but they are male or female from the beginning...... but I could be talking out my arse much like the author of many a book?

The way the article reads is exactly the way I understand genetics to work. That a “true female” cannot be coaxed into becoming a “true male” due to environmental factors... I could be totally wrong, my emojis do cloud my thinking from time to time.

And by what the books say isn't that stressing a plant into changing sex via an environmental factors = hermi
I love emojis???. Not that there's anything wrong with that

Furthermore.... The excerpt from the book says absoloutely nothing about influencing sex with environmental factors at the actual time of germination... only environmental factors AFTER the first set of leaves... these seem more like tips to avoid intersex traits from revealing themselves.

Everyone here was/is being 100% civil so Im not sure what was said to "piss you off"? Might wanna switch to decaf.

If you want to call that a fact your gonna need to back it up with some sources man ... I've heard that claim as well but always attributed it to bro science.... I ran 20 regs recently... one strain was all female, one mostly male... same conditions... so personal experience would suggest environment doesnt play a major role... but i wouldn't call that a fact since it was only 20 seeds

You were just saying in another thread one of the problems today are people are too set in their ways and aren't willing to see other perspectives... but then when another user questions your assertion you fly off the handle .... plenty of room there for a civil conversation...

Your response made me think I was on RIU for a hot second .... come here to get away from that crap

Let's chalk it up to a bad day and move on eh?

That’s all, I would hope someone making a claim like this would be able to back it up with more than just the anecdotal experience of running a few beans and then re-posting their findings as gospel. A book written about cannabis 40 years ago is also not really the most reliable source. New science is published almost daily and I feel it’s so crucial that we NOT perpetuate the misinformation cycle. That is what truly separates pH from other platforms. Our collective desire to advance the knowledge database for the community to use later on. I wasn’t attacking anyone personally, I just don’t think the info out there is accurate. That’s why I was asking , because I am trying to understand it better.




FWIW: Please know that every time I post here on pH, it comes from a place of love. I am not trying to embarrass, reprimand, or assert myself as some sort of master grower. I have a genuine passion for the science behind cannabis, and I just want to learn more. Plain and simple. I am not big on “gotcha questions and answers” that are ever popular on those bigger forums. If I am sharing something with another member, it is most likely because I have experienced it enough times myself to share about it confidently, and I just want to help out, I never just regurgitate shit I read on forums just for the sake of it... Theres a name for that, it’s called shitposting, and it’s why the other forums have lost their allure imo...

Either way, no hard feelings from this end, it’s not that serious, and I genuinely HATE wasting my time on nonsense like this. Just wanted to clarify as I know I can be a bit obnoxious at times, and maybe Some of my stuff may come across hard to interpret.

Moving forward.

I have tried lots of the above posts methods to try to influencing sex with environmental factors . I even put a bunch of banana peels in there one time to flood the air with ethylene ( i think that is the right word). I had a bunch of females the first try but the second time not so much. I suspect that my experiments were no different than a author of any of the books mentioned. They most likely had more knowledge than me BUT bro science none the less. On a closing note if you think you can influence the sex of a seed sprout you better do it fast because in a matter of a few days a Lab test can be done to determine sex

I peesonaly believe a regular seed has a 50/50 shot from the moment I plant it to become female...that being said, if I plant 20 and end up with 10 and 10 I was right with my original assumption...if I end up with 15 girls and 5 boys I smile and consider myself lucky...if i end up with 5 girls and 15 boys I....usually am ordering more seeds. Lol

What was this all about? Was that even necessary? If you haven't figured it out already, we ain't like the other forums. Your post reminds me of those other forums. Take that shit elsewhere if you're gonna wanna start some shit.

 

[spyralout]

Last year, when I was testing a buncha regs. I heard about the "volcano" theory. That the seeds with the "volcano" end were supposedly female. I spent time looking carefully at each seed, under a magnifying light, USB scope, etc to find the ones with the volcano. Well, I ended up with several males. However, I did end up with an 87% female to male ratio. Coincidence? Probably. Genetics? Likely.

I too have heard years ago from an oldskool grower that if you put seeds under a T5 for 2 weeks, it will "feminize" them. This was when fems from Europe were like $100/seed lol. So I think ppl were trying to find any way to get away from those outrageous prices. I call BS on that too.

Ecological genetics of sex ratios in plant populations

www.ncbi.nlm.nih.gov

This isn't cannabis specific but its an interesting read on sex ratios in dioecious plants in general. In summary it basically states that while you would assume a dioecious population would have a 50/50 sex ratio in nature this almost never occurs. Life cycles, environment, selective breeding etc all alter the base assumed ratio.

For cannabis, where one plant can pollinate hundreds of females its unnecessary to have an equal number of males and females ... however, to ensure the survival of enough male plants to sexual maturity it also doesn't make sense for the ratio to be in that 1:100 ratio either.

Years ago I read that in nature cannabis had an approximate ratio of 35% males to 65% females ... but that it also varied by type. Cannabis types that had low rates of males were also more likely to carry the genetic triggers for hermaphrodism in the study... and weirdly they observed a higher rate of males in landrace sativas. Unfortunately I can't find the article anymore. I used to work for an online database company and had access to all these scientific journals for free... I miss having it haha. So much information at my fingertips.

Also none of those things you mentioned alter genetics ... they actually trigger a latent genetic response that we can then use to create new progeny with altered genetics

This i agree with this 100%. Mother nature is the only one that can manipulate seed sex(IMO) and i think that is done before the seed even develops. I thought @Fr3nzy 's post reflected this theory best

Lol

I too have always used the 50/50 rule when popping regular seeds. From my experience, more times than not I have usually ended up with more females than 50%. However the hand full of times when I popped less, (2-4 seeds of a specific cultivar), and ended up with all males, or more than 50%, I just chalked it up to bad luck of the draw. Thankfully, that's rarely happened. I typically end up with more females than I have space for.
