Seed Predisposition

[natmoon]

18 males is a very rare occurence. You might say impossible.

Surely you see though that a genetic propensity for sex reversal would work to cannabis' detriment. All males cannot continue the line.

Where were the seeds from?

The seeds were the triploid/whorled sativa male crossed with the blue mostly indica.
I used that seeds shape chart thing and selected 18 good looking seeds of all shapes and sizes and asked people to judge which they though would be which sex.
According to the chart many should have been females but none were.
I have 7 out of 10 females though on my pppxblueberryxsativa from the same sativa under the same hps lamp so i have to admit now ive thought about it a bit harder you must be right or the pppxs would all have been male to.

So i guess i got unlucky and selected 18 males seeds purely by chance or maybe life itself used me to prove that the seed shape chart is bullshit lol

Heres a pic of the seeds that were all male.
I thought that according to the seed shape chart to determine sex there was a good mix of difference but it wasnt so.

maybe you read the chart backwards.

I asked other people to guess based on the chart.
I didn't make any guesses myself.

I hear that, at one time I was so confident I could predict males and fem's just a few days into veg' that I made a thread about it on here. Everything was reversed. The fems all grew like males but turned out fems, and the opposite for males... needless to say, i made a sharp exit on the thread.

 

[natmoon]

Yeah seems to be something thats not possible to tell from a size and shape chart.
Heres a link to the thread asking people to guess based on that chart.
Obviously the chart doesn't work.
I now also believe that sex must be predisposed and has nothing to do with size shape or lighting

I tried the chart thing too on this grow, and it was out. It did however work in favour of the females, but this is just luck.

 

[mal_crane]

I always veg' 24/0. I always get a decent ratio. I'm on or around 50/50.

Jorges Cervantes got the information from DP. Their experiment was on feminised seed and the environmental influences that can prevent 100% female plants.

This got confused with real plants and the bullshit spread very quickly. I don't think Jorges cares whether it's actually true or not.

And I used to veg on 24/0 and got the same ratio of 50/50, did my research, experimented with many grows and because of the results I got I only grow with 18/6 or 12/12 depending on what type of crop i'm going for and now I only get 5-10% males. Just something that works for me, I'm not saying you're wrong and I'm not saying you're right.

Now if you'd read my entire article, I said the information was on feminised seeds, however Cervantes did use this information before DP. Dutch Passion simply added to it. I also said I did not agree with the article and was only typing the results of MY OWN research not scientific fact!

DP actually devised and did the experiments... so if Jorges didn't copy it from them, who did he copy it from?

And by declaring this 'research' of yours you are agreeing that environment can sex reverse cannabis.

 

[mal_crane]

No dude. What I'm saying is seeds are not predetermined. Seeds carry with them both genes for male and female. Some seeds have a more dominant sex gene. Therefore environment has a factor in which gene becomes more dominant. Let's see your 'research'.

It is you claiming to be bringing something new to the table. Etiquette decrees that you show me yours, so to speak.

I also never once said anything about predetermination, this is a completely different thing to predisposition. A good definition for predisposition is within your own words, the part I underlined.

Once the seeds have developed within mommy the environment can not play any more part in the the development of the seed. The genetic code has already been established.

So just from using an 18/6 light schedule you can get 90 females out of 100 normal seeds? I smell bullshit.

 

[mal_crane]

Only stating what I've done in my own grows man. Show me your 'research' that the seed's predominant sex isn't affected by the environment, as that is what you are bringing to the table, correct?.

Of course the dominant chromosome can be affected by the environment. Plants go hermie.

The research is all over the web in scientific papers etc... do your own research...

Yet someone that can guarantee at LEAST 90 females out of 100 seeds just by using an 18/6 light schedule, doesn't need to do any research, right? You got your experience. Your 18/6 light schedule works miracles.

Is this the only thing you're bringing to this thread, your bullshit experience?

Go away and come back with some facts.

 

[mal_crane]

I've never seen someone who can't acknowledge, let alone appreciate, another's finding and consider them bullshit. I have never stated that any of my research as fact either. I'm telling you that, after recording all my own personal findings researching the DP/Cervantes statements, that the environment does affect the plants dominant gene. When will we see you apply these factors to your own grows to prove me wrong? You can call my findings bullshit so lets see your own results.

I used to grow with an 18/6 light schedule. I have done it in under both blue and red light... odds are always the same.

50/50 always evens out in the end, yet if you flip a coin it is always possible to get 10 heads in a row.

 

[mal_crane]

What does red and blue light have anything to do with the results I brought forth? My results only talked about light schedule, temps, and humidity. Put all of my findings to test, I'm waiting. Prove me wrong using the conditions that I tested. Let's see it.

I don't need to prove you wrong, your bullshit is clear for me to see already.

The fact that you don't even comprehend what effect light spectrum has on the environment speaks volumes about your bullshit claims. You have very little understanding of the subject in hand and, quite frankly, you are now starting to bore the shit out of me.

Wow try reading that one again and we'll see the less intelligent one. I SAID WHAT DID THE COLOR SPECTRUM HAVE TO DO WITH MY FINDINGS NOT WHAT AFFECT THE COLOR SPECTRUM HAS ON PLANTS!!!!!! Do you honestly think that after the amount of grows I have, that I wouldn't know the difference in what color spectrums have to do with vegging and flowering? Blue for veg, red for flower. When using cfl's, 6500k is for vegging and 2700k is closer to the red part of the spectrum for flowering. Read before you throw your own bullshit around asshole. I said prove to me that MY FINDINGS ARE INCORRECT! Why don't you have a little more respect for the fellow growers here. We're trying to help each other, while lately all you have done is thrown around bullshit from one thread to the next. It just seems to me you're a little bit afraid of being wrong here. Instead of being condescending me, lets see a little action to prove me wrong. I'm still waiting.

Personally I think seeds are pre-determined from the moment of pollenation. A bit like having a baby, the sex of the baby is determined the moment the egg and sperm meet and the cells divide. An embryo/baby generally doesn't change sex halfway through gestation.

I don't think a seed is pre-disposed to be one sex or the other, I think that moment decided the instant that piece of pollen falls on the stigma of the pistil of the female preflower.

Of course I have no proof of this, but then how can anyone prove that they're able to change the sex of their seeds to female?

I used to grow 18/6 and a year ago starting growing 24/0 .. I still get a general 50/50 ratio with seeds germed.

yes you're right... me too. All these guys think it makes you a better grower to get more females, when in reality it is purely down to chance.

 

[ccodiane]

Just like you I wanted to see evidence of this. How could they test it in the first place? How long would it take for them to be sure? 50/50 evens out in the end, but when is the end? A 50/50 ratio seems the most likely to me, no matter the environment.

First page to last. Have you satisfied yourself?
