Ok so i hope i can get this thought onto internet paper... an please if ur gonna post some uneducated 4 word answer as to why u think or dont think this is a good idea, move on...

Is it possible to force sex on a plant that has not shown its true sex yet??


example. started bunch of seeds. few weeks later big enough to take cuts. That seeded plant does not exhibit sex, yet. I never introduced that from seed plant to flowering, or was it mature enough in veg to show sex. So at this point there is no visable sex.

took cuts from those plants to early sex them. Found a couple females and a few males. One of the males exhibits some qualities i would have liked to see in the other females.


So basically does a plant know from the beginning if its a male or female?

If a cutting that is introduced to 12/12 shows to be a male, can i make the original mother lean towards the opposite sex? Will it revert or just be an hermaphroditic nightmare?

bsafe an thanks for you educated input in advance... peace

IMO,
Sex is genetically predetermined.
However, it seems that most cannabis plants have an ability to lean to the opposite sex when put in stressful environments.

Of all the cannabis plants I've seen in perpetual grows, kept as clones (all females of course), I've only seen one female in my life, that you could grow in extremely unstable conditions, that would not toss a nanner... ever.

If a plant can be forced via environment I call it a hermie. If it must be forced w chemicals, I call it P1 Mother material.

I am no expert... just do a lot of reading & a lil chuckin.

if the plant has shown itself to be male from the cutting then your plant is a male! you cant persuade it to be female... not unless you are a magician.

I will always take cuts from the mother/seed plant and while they are rooting (always potential for stress) put the seed plant/mother into bloom. you will see sex sooner, if a girl keep the clones and mom, if its a boy and you're not breeding, discard him along with his clones.

EDIT: the mom or dad can be put back into veg as soon as sex is determined, if one wants to..

can one turn a boy into a girl??? Idono.. girl to boy is easy though. < cannabis not humans

everyone thank you for your input!!!! I kinda figured it wasnt possible, yet. Or that if it was forced to the oppsoite sex you would have to continually keep up with chem/hormone treatments.


I read different things through time. Some say sex is predetermined, some say the sex is a directly linked to the environment whether stress or happy. Read some say that sex is shown on the crown of the seed. Read some say you can influence sex by bringing females near the unsexxed seedlings. Ripening fruit can admit pheromones or alcohol vapors that may persuade female sex.

Snook, that is how i sex my seddlings. Great way to learn early what you have.

Hoping there might have been something i havent heard of.

Thanks for all the responses...bsafe

that Caldara method (I think that's how it is spelled) is IMO, BS.

IMO expression of sex in Cannabis is determined by a combination of genes and environment. Cannabis is a very adaptable plant, and all individuals have the potential to be either sex or something in between. I think it's slightly misleading to talk about Cannabis in terms of male/female - better to say some plants lean more to the female/male side of the spectrum.

i'd agree with you up to a point neon, but in the case of the OP, who is looking for a harvest of buds and no seeds, i think he has to see the plant as a male.

Hi there,

I'm honestly not so sure what OP really wants...
Anyway, sex in cannabis is (that has been proven with several different scientific methods) genetically determined, females have XX allosomes and males XY. BUT the phenotypical sex expression can be changed by applying stress or plant hormones. Females tend to show male flowers more easily than males show female flowers. Notably, a reversed sex will still carry the original genetic predisposition; a male flower on a genetic female will only inherit X (female) chromosomes whereas a female flower on a male plant will pass on X and Y genes.

Environmental stress is somewhat unpredictable whereas with hormones it's mostly known which one causes what sex expression. A plant hormone doesn't reverse both sexes but pushes the plant to express on or the other.

.

Am i the OP?, op abbreviated for operator?? Original poster??

if so then my thing was i saw some variegation in a seedling that reminded me of Chem D. it was the only one to express this, then its neighbor seedling expressed this variegation as well. 2 seeds to one net pot. Then i wasnt sure if it was virus related. so those 2 got tossed.

The plant in question ended up being a male. an i am not making any seeds nor wish to spread a possible infection. so out the trash it went



this was the plant in question. mind you there where 10-12 seedlings beside that where perfectly healthy. flood table, growstones or growstone hydroton combo, nutes where gh microbloom an calmag, 3/6 mb an 3 calmag mil per gal. ph 5.6-6.0 throughout.







then a healthy sibling next pot over
