How can I force a plant to hermie?

SmokingForLife · 11-07-2009, 09:28 PM

Yes, that is right, I want a hermie! Actually here is the deal... I have 3 flowering ladies in there 4th week and I have already culled the single male. One of the ladies is looking real fine covered with bright pink pistils and smelling like candy! I would really like to make some feminized seeds from her. I was thinking I would harvest the cola and main buds, then while I let the other females finish their lower buds, I would like to stress this one to hermie and hopefully pollinate herself.

Has anyone else done this before? I know it takes 4 weeks to make mature seeds, can she live long enough to hermie and make seed after the main harvest? Is there anything I can do to make sure she will hermie? I have read somewhere on here that being kept in 12/12 for an extra 2 weeks after regular harvest time would make a female hermie, but this seems like it would take about 2 months for this process?

Have you induced a plant to hermie via stress? Please share your experiences!

just run her long a month

keep her healthy....low nutes

if she's a 8-10 week normal
you should have pollen with in the extra month

Colloidal Silver!

underarock: Thanks! Will she live long enough to produce seeds herself, or will I have to cross her with another plant? If so, would it be worth taking a clone of her and so that I can get only her genetics. She is from bag seed and none of her siblings look/smell/taste nearly as good, nor show the pink hairs.

By the way, do pink hairs mean anything? Are they common?

SilentSmoke: Have you done it before? I was thinking about it doing one of her branches with it this week, but then I read that I wouldn't be able to smoke her afterwords because the silver gets all thorough the plant from the foliar feeding. Is this really the case? If so, then I guess I will have to wait until after the main harvest to do the silver. And here again, will she have time to seed herself and grow the seeds to maturity?

Sorry, this is my first grow and while I have read a good bit, I don't have experience yet.

- constantly being blown in same direction

- temperature shift, take plant from grow into cold night air and back.

- allowing to dry out, then only giving enough water to survive; water normally once you get bisexuality for survival.

- have a light flicking on and off over time

- shining a ray of light on a branch during dark cycle ; is the only explanation i have for some isolated incidents.

- if you do it, do it in a quarrantined space, i am still getting pollen contamination from my first grow. Let us know how you go. nigel

your going to need another female
I think it takes a month to produce seeds
I think once you get it to produce male flowers
getting it to go another month might be tricky

plenty have done it...have to read some journals

ZoomBloom had a thread on how to do it with the silver

Jorge Cervantes Indoor Marijuana Horticulture 2001 section two - chapter 10, page 285:

Quote:

...Experimenting with hermaphrodite plants is often very difficult to predict and control, Some hermaphrodites are 10 percent male and 90 percent female, while others are 90 percent male and 10 percent female. If experimenting, use pollen from plants that are predominantly female. Hermaphrodites are freaks of nature and all too often the product of a stressful and inconsistent indoor environment.
Growers manufacture the outdoor environment indoors and control the normal life cycle of cannabis, Creating summer in December, cloning, prolonging the life cycle, leaching nutrients from the soil, stresses even the strongest plant. Couple this stress with freaky seeds and freaky plants will often result. Exposing flowering plants to 48-72hrs of darkness will prompt most females to grow a few male flowers. Other environmental stress that could cause sex reversal include excessively high humidity, over-pruning, and old age. Females severly stressed for any reason are more prone to develop a few male flowers. See "breeding basics" for more information...

nigel: Thanks! These are exactly what I WAS looking for! Great advice on keeping it contained as I hear that it is easy for a later grow to get pollinated via pollen left from other grows back.

Underarock: Thank you, I checked out Zoom's (I had actually looked at it before too). His chemical is STS which is different from Colloidal Silver. I will keep an eye on his results. Thanks for answering my question as to will there be enough time for her to pollinate herself (No).

bobbooty: Awesome! Thanks for the info, but the book which contained it was the best (and only) reference book I have read on Cannabis. It was an awesome read!!! That is actually why I hadn't posted back yet. I went to the book on Google Books to read that section, and ended up reading the entire book! (thanks to thepiratebay) Wow! I feel so much smarter now! Hopefully I can put all that info to good use :mj:

I am going to let the current lady finish as usual and I won't be trying any of this on her. From what I read, it seems that stressing a plant to hermie will make the correct pollen, but it will also lead to these tendencies to hermie due to stress more favorable in her protege. Trying to get male flowers from the Silver techniques will leave her unsmokable. I figure her pink pistils and abundance of trichs are not worth the potential loss of smoking the plant. Plus I won't be growing more bag seed of the foreseeable future as I have acquired seeds from a few different strains.

Here is my new plan. I will be using this method on my next crop set to be started on Jan 1st. They will be 5 Easy Ryders (Auto AK47 x Lowryder #2) Fem. I plan to use one branch on the nicest girl for turning male using homemade colloidal silver. I ordered the silver and I also ordered the chems for making the STS which ZoomBloom is using in his current thread just in case. I plan to use the pollen created from that single branch to pollinate the other branches and the main cola (since the plant should not be smoked due to the silver being absorbed into it's tissues. Hopefully I will end up with tonnes of Fem Easy Ryders so no more ordering $100 packs of 5 seeds! I understand that this selfed line will not be as vigorous as it's parent, is that true for this first round (S1), or is it more of a factor later down the road on like S10 or S20? If so, I will let her flower longer to start with so that there are an abundance of female flowers already present before introducing the colloidal silver which will inhibit the ethylene's effects turning the female to a male. This way I should get lots more seeds as long as they have time to fully mature.

I plan to journal this next grow so I should be able to journal the making and use of the colloidal silver as well. Hopefully all this will work out well! All the help is greatly appreciated!
