Stressing question.

[karmaxul]

None of my plants have ever been hermie. All of my seeds have always been female. Thousands of plants and thousands of seeds. I only got them when I stressed the light cycle. Was I just lucky?

How do you know there wasnt one tiny male flower somewhere on your plant, self pollenating some of the buds? you cant ever be sure.

graph just explained the relivence of XX chromosome seeds - apologies karmaxul I was just curious, I hate the concept of possible misinformation

[karmaxul]

Trust I would have seen it. I was in my grow rooms 50 hours a week on average.

I'm about to start a thread about XX females. If anyone would like more information on the subject, search there.

This is from the overgrow FAQ on feminised seed production:

How can I get my plants to produce femenized seeds?

There are two methods that I am familiar with; Light-Poisoning, and Gibberellic Acid Treatment, both forcing female plants to produce male flowers and pollinate themselves. I have employed both methods, and both have yielded satisfactory results.

NOTE: YOU MUST START WITH FEMALE SEEDS/CLONES TO ENSURE THAT THERE WILL BE NO MALE CHROMOSOMES PRESENT.

# LIGHT-POISONING METHOD: During the first three weeks of flowering, turn the lights on for an hour during the middle of the dark period. That is, 12 hrs. on, 5.5 hrs. off, 1 hr. on, 5.5 hrs. off, and repeat for the first 3 weeks, after which you may return to the normal 12/12 light cycle. This causes a plant to go "hermie" and pollinate itself, as well as any other female in the room. You must use plants originating only from female seeds or clones to ensure that no male chromosomes are present. The resulting seeds will produce NO MALE PLANTS!


# GIBBERELLIC ACID TREATMENT: Select your favorite female plant and spray it from approx. two feet away (first under the leaves, then on top). This must be done 2 weeks before the plant is put into the flowering light cycle, thus the need to start with female seeds/clones. DO NOT SMOKE BUD TREATED WITH GIBBERELLIC ACID! Spray the plant again after 2 weeks have passed, and place it under 12/12 lighting. This plant will "hermie" and pollinate itself and other females present. It will not produce as much pollen as a pure male, thus less seeds. However, these seeds will be 100% female.



CONCLUSION:
Now, femenized seeds have also been known to produce hermaphrodites. This is just an evolutionary safety precaution to ensure the survival of the species in the event of environmental catastrophe. All seeds have the potential to hermie. Variables such as pH levels, lighting scenarios, fertilizer problems, etc. will also be factors in the outcome of the plant's sex. Just keep 'em healthy, and give them your tender, loving care, and you should be fine.

I dont agree with either of those methods. How did you access the overgrow thread.

Its not a thread its from the FAQ - I treat most things from that FAQ with more integrity than some of the heresay I hear from certain people.

[Bluefunk]

So where as the guy from overgrow stresses his plant by giving it an awkward light cycle, his plant hermies and he gets fem seeds.

You stress your plant and it doesnt hermie but you get fem seeds...

Something doesnt add up here...
