female to male

[happyherb]

i would like to know if there is a way change the sex .somtimes there are uses for the males...happy herb..

hey,

It is possible to revert a female to male by stess of light hours etc and also thru acids. The main thing is to use a pure female when you do this otherwise the hermie traitwill be more domiannt in the offspring.

i have read that exposing a flowering plant to light in the middle of a dark period and generally stressing it results in a more potent product. Fact or fiction?

[happyherb]

yea i have herd that acids can change the sex so its good to know some else said the same .thanks.happyherb

aspirin and fluctuating light cycles

[boulder]

All kinds of stress induce plants to change from female to male/hermaphrodites. These include irregular light cycle, water stress, and some chemicals. Hermaphroditism is also a genetic trait that indicates even without stress.

In my understanding hermaphroditism in MJ plants is a survival response, so I can not see that it would increase potency in any way, that however has no factual basis, in order to get that you would need to first figure out the reason why MJ produces THC/CBD/CBN...

 

I would certainly not be doing it, seedy buds are a nightmare!

 

happyherb: the paticular acid I think your talking about is "gilbric acid" (not sure of exact spelling) its applied to certain parts of the branch to incude stress in order to produce pollen sacks and self pollinate the flower, seeing as there would be no true male pollination, the result being a completely female generation of seeds... fantastic right...? well maybe not, I havnt had experience myself but have heard alot of rumours that it causes plants with high hermie rates... and as stonedas said, if the mother plant you use has these traits then the risk is increased... once again though thats just what I've heard

to make male flowers on a female plant you need gibrellic acid, 0.02 grams of gibrellic for 3 litres of water

and 2 drops of Natrium hydroxide to liquify the gibrellic.

It is only useful for creating all female strains like Dutch Passion's. You need tons of seed because you need to find an absolutely female plant, so you stress 1000's of girls with 12hrs for 3 days and then 24hrs, repeat say 10 times and try and find a plant that has no male flowers (true hermies have hermie children, like hemp).

these plants are rare, you really need at least 500 females from seed, you would have best luck with true breeding indica's, as sativa's are more hermaphroditic.

Anyway in the end it comes down to the fact that not many people have room for this, anyway once you have your true female turned hermie cross it with clones of that plant before you turned it hermie.

I don't like the idea of this (selfing) I'm sure it is useful for outdoor growers but not practical to do yourself.

It would cost less to buy commercial quantities of feminized Dutch Passion seeds for the rest of your life, than to make your own feminized strain.

Happpyherb- you sound like you have one female plant you would like seeds from, the only way to do this is by backcrossing. Use a few males of a different strain and cross it with your female plant. then with your seeds (f1)use the strongest males to cross with your female plant again (mother & sons), then use the best males from those seeds (f2) and breed them with your female again. So your female is the mother, grandmother, great grandmother, etc... After alot of this you will end up with seeds alot like their mum. But, this also will cost a fair bit, sorry if none of this makes sense, I'm tired.

hey thanks white cluster. that is the first bit of information on breeding I've read and understood!

[wassily]

Gibberellic acid (GA3) is the go if you want to seed a female with itself. I use a .01 solution per litre.

Apply at the onset of dark period for 5 days in a row.

Wait a couple of weeks and you'll know if it worked.

Some notes:

After the final spray has dried make sure you clean the plant or branch with water before you dry and smoke it.

You can do this on one branch of a larger plant by covering it with a bag whaen you spray it.

Gibberellic acid does not store mixed for very long if it came from a powdered form.

You can get it from speacialty garden stores or hydro shops. It's not just used for pot, but do a search on the net to find a safer plant you can say you want it for. I'm pretty sure it's used on tomatoes.

Good luck. Be careful when you spray.
