Higher Female Ratio (Again..)

I know there have been a few topics on how to achieve a higher female percentage, but here is an article that had a few more conditions added to it. Check it out courtesy of cannabis-seed-banks.com

PERCENTAGE OF FEMALES
From literature 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. For growers who are well experienced, percentage of female plants is 60% - 90% female, but less experienced growers can end up with 100% male plants. The environmental factors that, according to literature, influence gender are:

 - a higher nitrogen concentration will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a higher potassium concentration will give more males (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a higher humidity will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a lower temperature will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- more blue light will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- Fewer hours of light will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- In later stage, as you increase the light, the plants grow faster and show more females/less males. Sixteen hours of light per day seems to be the best combination, beyond this makes little or no appreciable difference in the plant quality.
- Another idea is to interrupt the night cycle with about one hour of light. This gives you more females.
- Spray dilute Fish Emulsion ( 1 tablespoon per gallon ). When the plants have three sets of true leaves, plus the top sprout, give them a wetting spray of Fish Emulsion. Do it once a day for three of four days. Top and bottom of the leaves.
- To achieve 100% female plants is to expose young seedlings for several hours to an atmosphere of Carbon Monoxide. It doesn't hurt the plants, but it could kill you.
- Treatment of hempseed with ethylene gas will increase the resulting number of female plants by about 50%. Ethylene is produced by certain plants (i.e., bananas, cucumbers and melons), and these can be used to treat hempseed in a simple manner. About two weeks before you plan to sprout the seeds, place them in a paper bag or envelope and put that in a plastic bag with the peels of a ripening banana or cucumber. Replace the peels after a couple of days, and change the bags to prevent mold.
- When hempseed is treated with the female hormone estrogen, percentage of females that are produced will increase by about 10%. Dissolve a birth control pill in water and soak the seeds overnight in the solution. After the initial soaking, continue to treat the seeds by sprouting them on a paper towel soaked in the solution.

From literature it appears... I wonder where they got their information from? It doesn't sound too convincing starting an informative article in this way. It's almost as though they themselves do not have full belief in their information.

Also, less experienced growers can end up with 100% males. wtf are you talking about? Was that even in the article?

Experienced growers on this site have had nearly these kind of results. It's about genetics.

Also what's the part about a seeds predisposition? This means that the seed is predisposed to be a certain sex... which means that in all likelyhood, despite whatever environmental factors/changes you introduce the plant will turn out the sex it was meant to be.

To my mind, by fucking around like this you are merely increasing your chances of getting hermies.

i have rea dabout this debate a lot lately. weeds are adaptable by nature. its how they survive. im sure environmental factors could have some effect. if a fish or amphibian can change sex from its "predestined" sex, why couldn't a weed? when you rely on wind and other variables to find you a place to live, you had better be adaptable.

when? what stage? and how does this work or make sense?

Just to make this (almost pedantic) point, weed is not a weed it is a plant. It is likened to weed because of it's very distant relationship to the nettle and it's hardy nature. I mean you wouldn't spray weed killer on your plants and then expect them to grow back would you?

We're talking about cannabis, not a type of fish (as not all change sex do they) or amphibian (neither does all types of amphibian). We're talking about cannabis.

All things that survive are adaptable by nature, or they wouldn't survive. They'd join the ranks of the extinct.

Also the word I used was predisposition, why have you speech-marked the word predestined when this was not the word I used. That's like quoting me and replacing it with your own wordage. Insulting. Maybe, it's just your ignorance.

You've read a lot on this debate, have you? Well you need to go and read a lot more.

whats wrong with just growing multiple plants - kill the males and clone the females? doesnt that in essence acheive 100% female plants.

sure it sucks if you get all males, but perhaps karma would be at work with such a travesty

Wow, I'm glad my thread is getting some attention after 2 weeks. I personally have never really experimented with these methods. I only copied this information because I have used other information from that site. So skunk what you are saying is that basically the seeds are pre-disposed to be male or female. I hear people say that is true and then I see information like the above source floating around. I can personally say that because of all the different information I can not be sure to which information is true. The above ideas are not ones that I have created, but was hoping that maybe a few people would or have tried these and really do believe that these methods work. If anyone has 100% true information on how sex of a plant can be determined without putting it into flowering then please enlighten all of us. I for one can only plant as many seeds as I can and hope for the best.

Not me, that's what your article said. It said that plants are sexually predisposed. I like the way the article said gives more females... yet most plants are grown singly in individual pots, and all (I imagine) are treated with the same methods. This proves that these are not definite, proven methods. As (whomever it is) claims only certain amount turn out female anyway. Whereas if it were a proven method then all would turn out female. Even in the wordage of the article it sounds very touch and go. What exactly happens to the male chromosome, does it disappear completely... or not.

If anyone is to try these experiments it would be wise to keep a close eye out for hermies. Makes sense to me.

i totaly agree with skunkushybrid ( for once lol ) i definately wont be givin young plants high concentration of p or k ..as for the other methods that article mentions i dont know if they will work seems like BS to me ,and the problem is its allmost impossible to say ( if u used these methods ) wether or not they worked or you just got lucky with the m-f ratio .

This is called light poisoning. Its a technique used to produce a hermy, hermies produce feminized seeds - 100% females :)

It's a technique used to produce hermies (which btw if they are not natural hermies they WILL NOT produce 100% female seeds) not fucking females. You try and turn a male into a female and hermy is the best you are going to get. At least have the decency to know what you're talking about before relaying information to other people.

What's a natural hermie vs. an unnatural (?) hermie?

A natural hermy will produce nigh on 100% fem's, with a very small ratio allotted to males and hermies. Although the fem's produced from a natural hermy will have a stability factor that can turn them hermy.

A forced hermy will have a much larger variable in terms of male/hermy-female ratio. In other words you'll get many more males. Although there are techniques to encourage more females as the sex of the seed from these plants are very unstable.

This is where the mistake is coming in. The research mentioned by the starter of this thread is to do with hermies, not normal plants where the stability of sex is much stronger.

easy skunk. I was in dissagreement with the statement "- Another idea is to interrupt the night cycle with about one hour of light. This gives you more females." and that was a quote. If you'll read what I said after that, what I said is pretty much exactly what I read in the grow faq. So if that info is wrong, then it shouldn't be there, THAT was the info I was relaying. Take it easy Mr.! Sheesh, u call urself a stoner?
