Old school tricks for early plant sexing

This depends a lot on strain and grow conditions. 100% Indica’s for me usually show
pre-flowers around the 4th week and at times the 3rd week. Sativa dominant hybrids will take a little longer and 100% Sativa’s longer than the hybrids.

Once again I think this is strain dependent. I was using the 3 weeks in a general way and not as a rule.
I’m a stoner and hate typing so didn’t want to have to type out each timeframe for different strains.
I never start my strains under 12/12 as I want the veg time for my plants to get larger for yield. Most of the time I veg for about 2 months before flipping. I am only using early flipping when doing my OD grows.

Same here. The cheapest way. Lol

That depends on the strain…many don’t show sex unless exposed to 12/12 no matter what their age…others present in 24/0 at 6-8 weeks…again…all in the genetics!

So if I don’t signs of preflower by week 6 or so it could be a toss up. Oh well at this point I’m gonna flip in a few weeks so just roll the dice and cross my fingers lol I do that a lot it seems.
All this is great info for my next grow! Some of the ways seem so obvious but didn’t click. Thanks and I know this is a personal choice type thing but knowing all choices is the best way to pick yours.

Hey so are these nuts used macro to zoom please. Thanks

@Oldjoints @Pigeonman and anyone else what do you see? Thanks

I see nothing definitive in those pictures showing signs of sex.

If you zoom in and on the right side looks like a ball but I should let it grow some more to see.

Right side of branch, I see a ball that tickles the part of my brain that guesses male. I’ve flowered a lot of those little ball dudes just to make sure and so far I’m 0/XX on that game.

The important thing for us all to do, is to eye witness a LOT of pre-sex males and add it to our internal AI. Males do tend to show sex first, and so we’re all in the business of sexing male plants, NOT sexing males and female.

That takes 50% of the wrong guesses away. If you guess every plant is female you’d be right ~50% of the time. If you try to guess male and/or female, you can theoretically be wrong 100% of the time. So get good at sexing males (love that line).

Lastly, a lot of males could probably be sexed quite quickly but there’s a natural tendency to want a different answer. So our brains just don’t reject male appearing structure, instead they find ways to relay that the male appearing structure might actually be female!

Me too And I find you just get humongous plants after doing this and then growing outside all summer

I don’t see either :man_shrugging:

I hate when this happens which is why I’m tossing my plants in my 12/12 tent for a week and then moving them back to the 24/0 or 20/4 tents where they’ll show their bits soon enough. :+1:

Lol its there. One big ole nut hanging off to the right. @LD50 thanks I couldn’t agree more with what you said. Gotta get to sexing more males lol!

I’m looking at what @Lady.Zandra63 is.

I saw that also but it may or may not be a male sack. That is why I said nothing definitive. I would wait it out and the plant will tell you soon what it’s sex is.

Thanks for kinda forcing a learning experience I let the plant set 24hrs and its covered in male preflowers no question. Thank you.
So the other p/r I planted haven’t shown anything yet. I’ve been checking the stem points eith a loupe looking for anything that resembles any preflower so hopefully I can atch early with loupe. I would love to see early female preflower that cant be seen with naked eye. I know once I see it once I won’t forget so every night when lights come on then after I wake up I check all over with loupe so I can catch a glimpse.

and

are not mutually exclusive!

So I’ve been faithfully checking nodes with loupe looking for any signs. I did notice 2 thin white hairs on one node fingers crossed.

Is the best place to sex a plant is about 4-5nodes down from top? I noticed with the male that was where the first preflowers formed then the tallest tips then the rest of the way down. Is this a kinda standard way it’ll show preflowers? Or is it just random?

Every time I talk about 12/1 veg or 8/16 flowering light schedule, I get shouted down by people who say it can’t possibly produce as well as standard 12/12 or 18/6-24.

3 years of growing with 12/1 8/16 let me know just how wrong the “common wisdom” of internet growers can be.

It messes with a few of my clone-only cuts by shortening up internodal spacing too much, but it is great for most strains from seed. Saves a LOT of electricity and produces similar results. I’ve verified it myself.
