Possibly New Way To Determine Sex Through Leaf Developement

Ok, I grow with non fem seeds and absolutely non-stressed seedlings/plants. I'm not sure if it's a specific strain either as I've only had experience with the one I use. I've noticed that plants with faster developing leaf numbers tend to be males. For example, plants with 1,3,5,7 and so on tend to be males and plants with 1,3,5,5,7 development tend to be female. This is still a study in progress but so far I have 6 plants and the fast developing ones turned out all (3) male and the one slow plant is a female. Right now I have two about two weeks in so no sex yet but one of them is already 'fast' so I'm predicting that will be a male. The other is 'slow' so I'm predicting that will be a female. We'll see in 2-3 weeks. Maybe you guys can keep an eye on this trait with you new plants and see if this method works. Again, non-stressed plants/seedlings cause I'm aware stress through transplant can cause slow down in growth and cause this 'slow' trait. Stable happy candidates only.

Stressed how? I mentioned in the beginning about stress because it can slow plant growth and wanted to point out that my plants weren't stressed I believe and grew at a healthy rate. The cloth pot they sprouted in were the ones they sexed in.

I believe they weren't stressed at all. Never changed pots and they're in cloth pots so no over watering. I'm 12/12ing from seed I don't know if that stresses the plants but they look very healthy and I treat them very well. =D
 
there are things that could be stressing your plants you dont see.. unless you can talk to it like some kinda weedwhisperer. that'd be my super power if i could choose one.

but unless is a 100% confirmation its next to useless.. and i wouldnt want to be throwing out plants that might be male, that's a lot of time spent growing.. cant get that back.

Definitely which is why if this method works growers can save time and nutes. This method will only take about 3 weeks or however fast the 3rd true leafs pairs develop as opposed to waiting till flower. I'll continue to work with this strain and monitor my theory. Two to three more weeks and it's make or break cause I've got two (one 'slow' and one 'fast') on 12/12 now.

I actually wrote a few post about spotting females and males.Strong Males actually have a certain smell to them in early in veg and grows the fastest or close to the fastest but instead of branches forming in the nodes only single leaves do,and in a strong females branches are usually in abundance they wont really have a smell in early veg unless you really whiff the plants.Males produce leaves and then balls and females produce branches and flowers.Just wait for the the new growth between the nodes to start,if a single leaf comes its a male if it looks like 3 leaves are coming out its a female,but i still suggest waiting on a branch or leaf for a stem to occur and when it does you determine is it a single leaf or 3 growth points.

I am able to sex the majority of my plants by just setting them out on the back deck in April. Most of them will show within a few days.

Thanks for the input guys.

Hotshot, I'll keep an eye out for that characteristic however the early smell method might be a bust cause I remember distinctly that with the three males I had only one smelled very strong and stank up the space. The other two had none that I easily noticed unless I rubbed the stem.

Laney, how long are your plants in veg before they sex? Even with 12/12 from seed it takes me about around a month. With non-fem seeds and limited grow space an earlier method would be great.

Good to have you on board ddimebag, the more test subjects the better.

Hi - they will sex after just a couple of weeks. Most will anyhow. There are always a few that want to surprise me :)

All strain dependant. I've had plants show sex before the change to 12/12. Heck, I've even had some showing a couple of weeks from seed.

Using the smell method truly only works for the stronger males but the branching method usually finds the rest.
Take a look at your grow room and say you have 6 plants all the same height/age but different characteristics but
you notice some have branching and some don't,the ones that don't are Most likely gonna be males because they
were not made to grow flowering branches,only clusters of pollen sacks along the stalk.If male plants had big long
branches it would be harder for the pollen to get blown away as the foliage shields the sacks of pollen from the wind.

I'm not sure about the short side branches for males, HotShot, because I've seen lots of male plants with long side branches and one of the two I'm waiting on is growing long side branches and it's the predicted male plant. The 'slow' plant barely has nubs for side branches and they're both the same age which leads me to my very interesting update! The 'slow' plant is a female! I see four long and slender Calyx's. I should see the pistols in a day or two but I'm 98% sure it's a female. Other one hasn't sexed yet. Very interesting!

Ok guys time for the full update. Both plants turned out to be female! Full blown pistols are showing. So this 'slow' and 'fast' method is unreliable. I'd say it's a bust. First time I can recall being disappointed to have a female.. Thanks for the interest guys and gal sorry it didn't work out.

Males are stronger plants because they need to be, but i have grown plants from seed that went 1,3,5,7,9, and then usually stick to nine for 1 or 2 nodes, but one of the smaller ones was male, and a larger one, and there was a really small one that was a female, and my biggest one was female, and the second biggest was also female, there were 6 in all and one was a bagseed, also female
