Light Hermies males and females

Ok I got no idea who was the idiot who first said that light cycles afect the sex of your plant... it dosnt at all... the sex is in the DNA of the seed, it will become male, female or hermafrodite, if thats what the DNA says, it wont change the sex, by your light cycles....

The sex wont change if you pray, or if you put some pink water, or blue or whatever, it wont be a good male for breeding if you say bad words to it, when its a baby...

It wont become a female if you put a romantic movie repeating all day for days when its a baby or whatever.. I think i made my point..

LIGHT WILL NOT AFFECT THE SEX OF YOUR PLANT...

Ask any agronomist engeneer if the sex of a plant can be changed with light cycles...

however, won't stress during a plants growth can cause it to be a hermie that was NOT in it's pre determined DNA?

and what about gibberellic acid? when sprayed on a female plant with around 150ppm it can have a female grow male flowers for feminized seeds.

chemical process is a whole different story because then you affect the DNA light wont....

gotcha, i agree. just wanted to throw a response in there just so a newbe may take it that a sex cannot be changed no matter what. hope you didn't mind. :)take care

bullshit light does affect a plant and can change the results between male and female dont believe me try it lol

oh guys, am i glad that i read those replies above? after the incident i had yesterday with the timer, i feel much more relieved right now....i've read this thread started by Marimbas and somehow now i can understand what i've read from Dutch Passion a few months ago, an article about feminised seeds and a test they have made here's the link : http://www.dutch-passion.nl/engels/female.html Check paragraph numbered 1....it all makes sense to me right now......

[QUOTE=marimbas]chemical process is a whole different story because then you affect the DNA light wont....[/QUOTE}

You're wrong spraying gibberellic acid on a plant that has already distinguished itself as a male or female, cannot change the DNA :rolleyes: . It may cause it to develop male flowers but you're not altering the DNA!

you are correct nosehit. that was a technicality on my wording, but you can get male flowers on a female plant,,,i'm not a botanist :) later

The DNA of a plant, as the DNA of a human being can be altered by a constant contact of chemicals, or radiations. The feminized seeds are made by 2 ways (i know and IM SURE IT WORKS) taking seeds threw a chemical prosses, or putting them under a radiation prosses, thast why they are much more expensive than regular seeds.

You cant change the sex of a plant just with magic, what youll create is a mutation of the plant, and maybe make it develope the other gender flowers, BUT ONLY WITH A CHEMICAL PROCESS, OR RADIATION....

Dont fool yourself with idiotic sayings, its like if a girl would grow a penis if at night she gets her feet at 45°C every night for a couple years... THIS IS JUST ABSURD!!!

if you think the light or something so absurd as this will make a mutation on your plant, justr try it, over and over again, youll see how stupid your ideas are

i'm not saying you are right or wrong marimbas cause i'm not super educated on that and i know you weren't talking to me personally, this is just a general comment. but i thought it was a bit "not nice" to call other's ideas stupid, whether they are wrong or not. sometimes "stupid" ideas are little seedlings to creative ideas,,,, but that can be hindered if someone bashes someone else saying what they are saying is stupid.
you are probably right scientifically. i have learned alot from this forum in the past couple months ONLY by listening to many right and wrong and in between answers and researching on my own to figure out which sound more correct to ME. that is what is great about this forum and i know you have helped me in the past. thank you. hope you dont' take offense to me popping in like this, just felt the urge to reply to that.

First of all we were talking about plants your right a girl isn't going to grow a penis. However a slight deviation in the temp. of developing alligator eggs will certainly change the sex. So curb the 'tude brain trust.
Second, I said spraying a plant is not going to change its DNA (and were speaking about the sex not simple mutation) I never said anything about the seeds!
Third, Stress can most certainly cause male flowers to develop and it has nothing to do with genetics, alot of times plants will develop male flowers at the end of the flowering cycle, how do you explain this?
And there are many animals that can alter their own sex as a means of perpetuating the species.

Don't let it discourage you, he's not entirely right himself

Nosehit dont take it personal, you got your opinion, i got mine...
Kuri as well, you got an opinion and thats well accepted, as long as someone elses thread is not taken pesonal, or a particular discution.
Im simply sure about the sex of this plants, i know they can develop a mutation or a gender variation, but after a very uncommon situation, not with a very normal situation...

No worries, I agree with some of what you say. But I am not stating an opinion, it may in fact be an exception to the rule I don't know for sure, I do know that I have seen this on more than one occasion.

It has been my limited experience that a hermie will show female flowers for a couple of weeks before the male flowers start to show. Is this normally how it happens? I ask because I've only had 2 plants go hermie and both displayed this behavior.

normaly its the oposite, youll get male flowers first then female, but after all a hermie is a hermie and may go the other way, i dont think that what happend to you was because you caused it... I think those were predisposed plants, what i mean that the mother seeds were hermies...

I think it can. Plants aren't human. Frogs have been known to switch sex when there aren't any females around. Some will switch sex and become female (or it might be the other way around, but they can switch sex). There's a species of crabs that start out male, and throughout their lives they change sex several times. Yes, I think sex is determined by genetics, but I also believe that environmental factors can affect the gene expression (aka phenotype). There are lots of examples of environmental factors that affect the expression of genes.

Most cannabis plants probably have a certain level of predisposition towards hermie. It's probably due to natural selection and evolution. Remember, cannabis like all other has evolved to propagate it's genetic material (that's why sex feels so good for us humans, it ensures propagation of the species). A plant that has the ability to go hermie and self pollinate stands a better chance of survival than one that does not.

Some of course, due to selection of breeding stock are more hermie resistant (ie C99), and some just naturally hermie even if given good environment (thai's show this trait).
One little mishap in a light cycle won't or shouldn't ruin everything though.

hi all, i have found that muterlating a plant can do this , ( overtriming ) i know what you say about if its gonna be a hermie then its gonna be one and that is true, however during my early grow days i did hundreds of various experiments including trimming to force flower increase, these were not just random experiments but calculated and logged over a long time, i can say with a modest amount of knowledge that i did produce plants that showed hermie features from mothers that were know to be relible female stock, i also found that certain deseases can premote male gender on an otherwise reliable female, as for light altering a plants gender i cant say with any certainty but i do suspect it may happen, , i have had quality girls that have had shown male gender when my lights have gone up the wall, if you can bring male gender to a female plant by trimming, desease, heavy and feed starvation cycles, and by simply spraying with a certain sollution, then it may well do this under light stress, well thats what i think, i hope i aint rattled anyone but i just felt that i could say what i know, all the best to all of ya, i will be sitting here should you wish to reply

You can have both types of Hermaphrodite... Natural (meaning from seed.. it'll grow both flowers) AND forced Hermaphrodite.

This is done by purposely interupting the dark period with an hour of light...

for example.. on 12/12 you'd be off for 5.5 hours then turn the lights on for an hour.. then off again for another 5.5 hours..

do this for say a week - 2 weeks.. you WILL affect the sex of the plant... you CAN turn a female plant into hermaphordite by fucking with the light cycle at night...

I'll take Mel Franks & Ed Renthals PROFESSIONAL growing guide for 1000 alex...

Don't act like you know everything marimbas... because i'm positive you don't, try reading a book, you'd be suprised at what you learn

Thanks Bob you have showed everyone you are a total pro, and that you know everything about growing cannabis.....

Chappie you are right, on must of the things you say, i totaly agree, thats what ive been trying to say, you can mutate the plan or afect the gender, but not with light...

Even so i would say that mustly all hermaphrodites are caused because of the genetic of the seed...

It is common sense that altering the photoperiod of cannabis will force it to become hermaphrodic. That plant does this because it thinks that it's survival chances are at risk, so it grows both sexes to produce seeds, and thus continues it's species. Most of these things are just common sense. Just pick up a book published by any reliable grower, like BobBong has just said. Common sense.

Peace

you see. the thing is, i'm NOT a pro at growing.. i'm very far from it... but i've read enough reliable sources to contradict what you are trying to state as fact.

this is my very first grow...but it's funny how after simply reading a book, i can very easily say i know more about growing indoor plants ( not just marijuana ) than half the people that claim they know.

P.S. you wouldn't ask a agronomist about marijuana.. you'd ask a horticulturist..

wow! i learned something in this thread. and im going to go google it and see if i can find places that back this up.

so if i'm in 12/12 and i interrupt the dark with an hour of light that it will cause a hermie. some may laught at me, but i want a hermie so i can get seeds. i don't have a male.

so my question is if i cause a hermie in this way, will the seeds become hermies? or will they be feminized? thanks to anyone with replies on this.

I might be wrong, ive readed a book, and i have some more exp in outdoor than indoor, even so, In mexico i dont know if an horticulturist with a bachelour even exists, i got a friend who i a agronomist and i asked him...

even so i dont think light can afect but still i might be wrong, About the common sense i dont see how it is a common sense thing, that light can affect the sex of a plant??


I think the bottom line is that kuri make the experiment, but dont do it with 1 plant, do it with at least 3... so if its real youll get only hermies... and ill shut my mouth totally

no dont' shut your mouth, i'm not trying to do an experiment to find answers, i'm trying to grab as many opinions from people and then try what i think may work. i'm just trying to get seeds from my plants that are luckily all female.

i was planning to do a plant with gibberellic acid to see if i can induce male flowers AND after today when the time comes, i'm going to try the 5.5 hours off 1 hour on and 5.5 off for the 12/12 night cycle to see if that is easier to get male flowers.

so no, PLEASE don't shut your mouth, it is ALL of our opinions and separate knowledge that helps us all progress, now when it gets out of hand and there is name calling, then i would agree on the shutting of mouth :). thanks again

hi again all, may i suggest that if your gonna break the light cycle like you say then maybe extend that hour to 90 mins, it would work i think with one hour, but 90mins is sure to confuse them gals, i feel for you kuri, aint it poss for you to get normal randomly selected seeds mate, is there know where you could ponce some, you would do far better to select male plants from normal seeds than to try and create seeds from a mother with forced male jender, you might end up with all hermie babys, now that would be sick, normal randomly selected seeds on average are gonna give ya 50 / 50 m/f offspring, at least then you will have better stock to start your projects, having said that you could still come up with a hermie or two, just that your chances are gonna better, some hermies dont give ya that much stash mate, it would depend just how queer they have turned, if ya have got a hermie thats only got a little bit of male gender, that dont mean that its offspring will also be so lightly altered, in my humble opinon i would keep away from hermies and try to create somthing more relaible,i throw thousands of seeds away if just one of the mothers show any sign of male jender, hermies are good to learn from mate, but they can be a real pain in the arse, and can fuck a grow without ya knowing, all the best

I wouldn't force a hermie to produce seed. Reason being, like I said above, each plant will have a different predisposition to go hermie. So if you screw with light cycle and find that a plant hermies easily and then you use that hermie to produce seed, you have a higher probability of getting hermies since the mother had a high predisposition to turn hermie.
I think STS is a better method of producing male flowers on a female plant. It's works through a chemical pathway (something to do with ethylene) rather than a mutation. I just buy seeds each time, I don't feel like wasting my time. I don't have the room nor am I willing to take the risk of large scale growing needed to find really good phenotypes to make my mom and pops. Selection is a big part of breeding and creating seeds. which is why I'd rather let the pros breed them, you might grow 10 of a certain strain and select, the breeder might grow 100+ for their selection, which do you think has a better chance of creating genetically superior seeds?

Well, IBLs would be a different story.

what is STS? as a method to produce male flowers? the reason i'm thinking about doing this is because i only have two females and there will come a time when i have to take a break from growing and the i will have nothing to start up growing again, therefore i would like seeds. i found these two seeds i a bag i got and luckily both of them germinated and were females.

what about using gibberellic acid? will that be better than forcing hermies with stress or light cycle changes?

i would buy seeds and start with that, however i'm in a country where it is not legal so i would have to buy from abroad and i'm not comfortable with that. any suggestions?

Collect pollen from the hermaphrodite and pollinate female only plants. The resulting Kannabis seeds will produce female Kannabis plants with out the male genes. Gibberellic acid will produce male flowers on a female Kannabis plant.

Good Kannabis Growing!

Thats what I thought, thats why I was so shocked when I saw the male flowers after I thought it was a girl (the damn tranny) :D . Oh well I seem to do everything bass akwards at first. :D :D :D

SSS that seems so logical, I never thought about it like that. :o :o

Light stress can cause a female Kannabis plants to hermaphrodite period. That is a fact folks. I have been around Kannabis grows since the 1980's so my experience is not limited. Also check most any Kannabis FAQ's they will confirm light stress can cause hermaphrodites in Kannabis plants period.

Good Kannbais Growing!

Really? I thought that everyone knew that. This was one of my theories long ago. I then researched it, and found out I was correct. Well, most of my theories are correct. :D

how can a plant produce seeds without being a hermie? i posted a thread around this forum but nobody seemed bothered replying......i found out 2 out of 8 plants with seed pods....both of them with female flowers....however there is not a male or a hermie in my garden....no male flowers were found, i double and triple check all 8 of them....i chucked away the first one that i found in fear not to ''contaminate'' the rest of the garden two days ago....now i see te second one started growing some seed pods but male flowers do not exist in the garden.....how is this possible? why is it happening? what should i do? gladly both of them are from the small ones that were misplaced from the beggining into the cow manure and have not grown much.....the rest continue building their buds....

you can cause a plant to go hermie if there is severe stress, some are more prone than others. It is in theird DNA to do this because if there is stress there may not be any more plants of the opposite sex arround to pollinate/receive their pollen so they go hermie. Same reason they go hermie if let flower to long, they are going to die and need to produce seeds.
