Sexing Questions

[FLORIDA MON]

I pretty well know how to sex mj plants from seed.

But, at what age or size should you start sexing your seedlings in the 12/12?

Can sexing them too early cause high rate of males or is this disposition already programmed in the genetics?

Thanks all:thumbsup:

genetics sex is inbeaded in dna and rna although females plants still have dormant male traits within that take over if environmental stress occurs to an excess level and as far as when can u flower u can flower from day one but u wont yield anything usefull when u flower is dependant on how much growspace you have tomatoe plants tend to double-tripple size once flower is induced some even quadrupple(dependant on strain and growing technique) so say u have 6 feet of growing space from top to bottom i'd say flower at or around 2 feet tall growing techniques differ upon grow space hense LST grows SCROG grows SOG grows ect..ect.. hope this helps best of luck

NEVER sex until your ready to go all the way.. that ismy suggestion
Take clones..
then 12/12
and then throw out the clones that are from the male plants..
a bit more work... ahhaah
but who gives a LOVE
and it expidites results.. BUDS...

love

Thanks very much for your good words of wisdom!

the best method imo is to veg the plant until it shows on it's own(preflowers). most plants show preflowers between weeks 4-6 anyway. growing mj is a hobby that takes patience.

I agree, patience is very much a virtue in the cultivation of cannabis field. The more patience you have the better things will usually come out to be. During the vegitation period, the plant basically multiplies its potential end yield over time.

Goodluck <3

This is interesting... my White Widow plants are going into their 120ish day, and they still have no pre-flowers. 18/6 light schedule. 4 plants. No pre-flowers.

Any ideas? That's why I'm cloning for sex... the freaking plants don't show me their sex!!! virgins...

[orangeman]

Yeah never force a plant to sex. I read some where that forcing a plant to sex can cause self-pollination of some reason. I forgot how it went but I would totally wait until you really felt it was time for the plant to be flowered or what ever. Excuse me if I'm making no sence I'm fuckin stoned lol :stoned:.

[Da1KrayzieThug]

Turtle I'm sure you're plants are fine. Justaseed probably just had a lot of runins with strains that did autoflower.

[justaseed]

most all plants will show preflowers by the 6th week of veg especially if a 18/6 light cycle is used(some sativas could take a bit longer). the longest a plant has ever gone in my grows without showing preflowers was 7weeks and it was a bogglegum male. it is not just autoflower strains that show preflowers. i am very suprised that your ww's haven't showed at 120days. they must be monsters! the nodes are alternating, right? in my experience preflowers come before alternating nodes. post some close ups of the nodes if you can especially nodes on the main stem. i suspect that if you look hard you will find some. i just can't believe a plant would go 4 months without showing sex!

Ok, I'll snap some up-close pics right now and upload...

Now I really need to find those pre-flowers... as my clones from the "cloning for sex" operation just, um, died. :(

I'll upload in about 10 minutes.

I understand your point, but, only good things can come from this::
A- My plants do have pre-flowers, but I'm so fucking stupid I haven't spotted them.
B- My plants are a new, wierd mutation that doesn't show pre-flowers...

Anyways, in a couple of minutes...

Ok, I'm uploading a couple of pics, in all their 1.8MP glory... sorry for the big file size.

Please help me out... any pre-flowers showing?

CORRECTIONS: I checked my pictures, and the plants aren't in their 120ish day, they're on day 116 today.

Thanks for the help... It'd be great if I could find out my females, without having to clone for sex yet again...

Thanks a million,

i can't see any in those pics. look between the stipule and gowth tip. check every node on the plant. there has to be 1 somewhere after 4 months on 18/6! i'll post some pics of preflowers as soon as i can. also i noticed the nodes are alternating so they are definetely mature. if you read almost any reputable mj culitivation book it will tell you mj plants will show preflowers if vegged long enough(at least 4-6weeks). this situation is very interesting to me. now go and look over those plants very very carefully. i have used a 30x magnification jewelers loupe to spot/identify preflowers in the past. you can use a magnifying glass if you have one available.

Thanks man...
Darn, I forgot to tell you about the alternating nodes... but alas, you already saw it... yes, all 4 have alternating nodes.

I'll go look for those pre-flowers now... with the camera in hand... talk in a few minutes... :)

i'm very low tech and i can't figure out how to make my digicam focus on objects that are less than a foot away. i try to take a pic of preflowers and the camera focuses on something behind what i am trying to shoot leaving the branch i wanted to shoot all blurry. it's a sony cybershot. it was given to me and my wife for taking pics of the kids. there were great preflower pics on og!

[turtle420]

Hey Seed,
I'm working with this picture.
http://boards.cannabis.com/attachment.php?attachmentid=20858&d=1121285047

On your camera, check to see if one of the buttons display a "flower" type icon... that's usually for objects "closer than 18 inches away".

I checked my plants:::
Ok, being guided by the picture I gave in the link, I can tell you two of the plants have very long "Stipules".

Close to the stalk, at the base of the Stipules, the best I could see was one little ball... it didn't have "Pistils" growing out of it, but it was only one... not a couple (like a male plant's).

I'll keep on searching... I'm going to take them out of the cabinet, because the fucking 400W MH is really the shit... Jesus! I can see xRay vision now!
lol

BTW: Thanks for the help man! This is just giving me hopes to start my grow soon!

[justaseed]

that's a good diagram. keep a close eye on the "ball" over the next few days. it could be a growth tip but you will know for sure in a few days. i wish i could contact bLAZEoFgLORY he knows his shit and ran the sexing thread at og. i never contacted those guys any other way than pm so i don't have any e-mails. good luck with the search. i'll keep check my computer this evening in case you find something interesting.

what did you meen by "start your grow soon"? they're not your ww's?? probably none of my business, i'm just curious

[justaseed]

i did it!!!!!! sort of

the preflowers are circled in red(all female)

[turtle420]

Yeah, they're my WW... but I'm growing my mother plants... I'm planning on staying with these pants for years to come... so that's why I've LSTed the shit out of them.

As to "starting my grow soon", because I'm growing mother plants, I still haven't started my actual bud-producing grow... I want my buds now! lol

Hey aSeed, thanks a million for this.

I see the pre-flowers... but they're TINY compared to yours... I can see yours in your pictures.... I can make out the "Calyx" and "Pistilates" in your pictures. My girls have that, but I'm telling you, they're micro... super small.

Anyways, if I'm not mistaken, I've got a confirmation of a female... my two headed monster... that's a female.

In addition, I think that the biggest one of my plants is a male... I just see one tiny little ball by the side of the "Stipule". But the female, I can see the very, very tiny "Calyx" with super short "Pistils" on top of them. That's a female!

I'm soo happy... THANKS JUSTaSEED!!!!!

justaseed you wouldnt happen to have pictures of female main colas when theyve just begun showing sex and a male main cola to see the difference in apperience...just something i'd be and im sure many others would be very intrested in comparing... by the way good job on those female preflowers that helps alot:thumbsup:

[justaseed]

i have lots of females i can take pics of but unfortunately i kill all my males as soon as i identify them.

turtle- awsome i'm glad you id'd 1 at least for sure. usually the largest is always male. that has been the case with every batch of seeds i have grown. you should look into bonsai style mothers. i can fit my bonsai mums into a 10" square space(almost) and still take 50x more cuts than i need every 2 weeks. my lights are off till 4pm so i can't get to my vegg room until then without letting light into my main flower room. i will post pics of my bonsai style ww mum after 4pm. it's a shame, og magazine had a great online article about training bonsai mums. that's how i learned. i can fit 4 mums in a space 20inches wide x 20inches deep x 12inches high!!!! you just have to prune alot and do some root pruning a couple times a year.

Hey justaseed, thanks for the info. Beautiful plants dude. Not a single brown or yellow leaf.

What is the yarn looped around the base of each plant for?

[justaseed]

that supports the stem so i can use another string to tie the main stem so its paralell to the soil(lst)

[turtle420]

you should look into bonsai style mothers.
Yes, definitely...

My girl is very short (LST) right now... and bushy. I plan on placing her into my mother cab (12"x24" with 24" height). So bonsai mother would be excellent!

I'm sure she's root bound right now... as the pot has a 8" height and 8" diameter... plus there's TWO plants in there... not one.

Anyways, I'd like to keep her short... nothing big. In the future, maybe plant another strain... Bubblelicious?

Thanks guys!

once the kids are asleep i'll take some pics of my ww bonsai mum.

[justaseed]

here she is. i will take some cuts in a week or so and she will be alot smaller after that. it's just like cutting the grass every few weeks and it keeps her really small. also here are a few more female preflowers.
