Actually no this is not true! Feminizing just increases the chances of a female it does not guarantee 100% that the seeds will turn out female. I've gotten female, hermies, and even males from feminized seeds.
Where did you get your feminized seeds?
Properly made feminized seeds are 100% female. I do not believe you have gotten males or "hermies" from feminized seeds, it is impossible.
I have made thousands of feminized seeds. Every one that I have germinated was a female plant. There has not been one male or hermaphrodite.
I do not believe you when you say you have gotten "hermies and even males from feminized seeds."
Properly made feminized seeds produce 100% female plants. Feminized seeds do not have a Y chromosome and can not be male.
First we have to make sure we are talking about the same thing.
A hermaphrodite can not come from a properly made feminized seeds. A feminized seed does not have a Y chromosome. Hermaphrodites have both an X and a Y chromosome.
If you had plants from properly made feminized seeds that produced male flowers, it was most likely because you stressed the plants, not because of the genetics. The parents of that plant are just as likely to produce male flowers under the same conditions.
The way that companies create feminized seeds is by breeding a female with a hermie.
No, that is not true at all.
This is probably the biggest myth surrounding feminized seeds.
Feminized seeds are produced using a female plant, not a hermaphrodite. You are the victim of a myth perpetrated by bad growers and/or people with no feminized seeds experience.
Again, a hermaphrodite has an X and a Y chromosome. Female plants do not have a Y chromosome.
If you use colloidal silver, one of the most common methods, you trick the plant into activating natural hormones that will produce male flowers. Only the sprayed areas will be effected.
The spray does not add a chromosome or even change dna. All that happens is a natural part of cannabis, a survival mechanism, is activated.
The resulting seeds will not have a Y chromosome. They can not be male or hermaphrodite. Environmental factors can not make a feminized seeds male, the Y chromosome is not there.
The sprayed plant is not a hermaphrodite, it is a female plant that has had its hormones activated on a specific part of the plant. The genetics remain the same, dna is not altered.
From what I've seen personally, environment plays a key role in whether a plant becomes male or female
How do you quantify that? How do you know you get more males or females? Did you have a control group?
From what I have seen personally, environment plays no role in determining sex of cannabis from seed.
Again, if there are feminized seeds, why can't there be male seeds?
I have not come across any evidence that environment plays a role in sex determination. All I have heard is stories.
I have heard of people that claim they can tell the difference between a male and female seed by looking at it.
I saw a chart on another site that showed differences. I pulled out some of my regular and feminized seeds to compare and was struck how the seeds compared to the chart.
I have no idea if it is true, but one guy claimed to be about 90% able to tell the sex of a seed by looking at it.
the next time I grow from seed, I am going to give it a try.
I also have an opinion about regular cannabis seeds that I can not verify. I think that cannabis seeds naturally produce more females and not because of environment.
If you think about it, it kind of makes sense. In a wild population, one male could seed hundreds of plants. I think that cannabis produces more females because only a few males can seed a lot of plants and provide genetic diversity.
That part is opinion based on all the regular seeds I have grown over the years. I have always seemed to get way more females. This is in wildly varying environmental conditions - outside/inside, soil/hydro.
