Feminized Seeds...

CobraII · 09-15-2002, 11:32 AM

I have been thinking a lot about how seeds are actually feminized. There is not much info out there.

This is what I found at Dutch Passion:

1. a higher nitrogen concentration will give more females.
2. a higher potassium concentration will give more males.
3. a higher humidity will give more females.
4. a lower temperature will give more females.
5. more blue light will give more females.
6. Fewer hours of light will give more females. It is important to start these changes at the three-pairs-of-leaves stage and continue for two or three weeks, before reverting to standard conditions.

Ok, raise nitrogen, lower potassium, raise humidity, lower temp, blue light spectrum, fewer light for 2 weeks.
Still, what are the chances for all female seeds?

Lot's of good threads around on that.......
Here is the best- searching will get you the rest.

That thread is mostly about hermies.. does not explain the process of creating feminized seeds.

Is it some sort of secret!?

If you read far enough it is explained. You really can't talk about producing female seeds without talking about hermies also. Until you learn the differences between types of hermies, all the discussions will go over your head.

There is too much speculation. Hear-say.. ect..
Do you know the facts? I would like to be enlightened.

Found what I needed!!!!!!!!!!!!!

It is possible to cross your favorite two female plants to create a new strain of seeds that will produce all female plants. Preferably, these two plants will be different types of plants, not from the same mother's seeds.

This will create the best offspring, since it will not lead to inbreeding. It is easier to gauge the quality of female plants than male plants, since the smoke is more potent and easier to judge it's finer qualities. Plants from seeds created in this fashion will be all female plants since there will be no chance of male chromosomes from female parents.

Use Gibberellic Acid on one branch of a female plant to induce male flowers. Gibberellic Acid is sold by nursery supply houses for plant breeding and hybridizing. Spray the plant once every day for 10 days with 100 ppm gibberellic acid. When the male flowers form, pollinate the flowers of your other target female plant you have selected. Just pollinate one branch unless you want lots of seeds!

One question.. how do I measure out 100ppm gibberellic acid!?

Screw directions. I bought a TDS meter to properly measure parts per million.

You do realize that when measured incorrectly (even if off by a tiny bit) you will ruin your whole crop?
And I'm curious how you found that one in a hundred pure XX female??
Here's another link you might find interesting.

That's why I bought the meter.

I am not SURE if I have a xx female, I am sure it is much less than 1:100, that does not sound realistic. That was a good read, and I'll have to try that method to find a xx female as he calls them.

Most of that "interview" was rambling. Seems to me he is trying to make it sound more complicated than it really is, and he even admitted that he didn't want to tell them everything (that's BS).

From what I understand from that article is you basically stress the plants until you find one that is stable, then force it to produce male pollen sacks.
