I'm thinking sex is genetically coded. I'm not 100% sure of this, but it seems the logical conclusion to me.

Why are feminized plants always females? Because the parent plants have only female DNA. If environment was capable of altering sex (DNA) then wouldn't we see a significant amount of feminized plants come out male??
That's exactly what i was thinking. I've looked around on other sites and googled a bit but i couldn't find anything better than guesses. It's kinda hard to prove anyway, you have to pop a lot of seeds to get good results.

More blue light and lower temps will definitely result in more females. Too much red spectrum, and high temps during veg, stress young plants out. When plants get stressed at any age, they release male hormones, resulting in male plants during veg, or hermies during flowering. I've posted my findings before on this subject, but just to recap, here are some of the results.
6500k - 5 females out of 5 seeds.
3700k - 4 females out of 7 seeds.
LED flowering light with a red heavy spectrum - 2 females out of 8 seeds.

Genetics are half the battle, environmental conditions are just as important.

Really? Let's say you ran your vegging beans under 6500K [+blue], and topped/cloned at 4th set of leaves. The clone then roots and veg under heavy red LED.

Since neither mother or clone had shown sex, it sounds theoretically that your blue mom could birth a red boy.

thanks for sharing your results! I think that it would take more than 5 seeds to run this test as it is not a good sample size. The sample size is chosen to maximize the chance of uncovering a specific mean difference. it is a very interesting discussion and if i had the space I would run two rooms of 100 or more plants, but i will try all of the above techniques to see if it helps.

That's one hell of a word problem, so let me answer by saying, I have no idea.

Admittedly, those are just from my garden, and not a scientific study by any means. Never the less, more blue light in the seedling/veg phase has always resulted in more females for me.

We need someone to look at our seeds scientifically and tell us what's up with sex. There is so much guessing, and I mean no offense, it's all we have is first hand accounts of what works for someone else, but it has everyone confused as to what the correct answer is.. It would be nice to once and for all know if a seed has predetermined sex or environment determined.

You can pop 1000 seeds and get 600 males and 400 females you can pop 1000 seeds in those same conditions and get 100 males or really any number. If environment played a roll, IMO, then all seeds would come out the same, you wouldn't have lower number of males in lower temps. You would have 0 males in low temps or you could find the "perfect range" to get 99% females it seems that this stuff, to me, is just the randomness of regular seeds and people see what they want to see.

I have a hard time believing you can feminize pollen but if you don't feminize it the pollen doesn't have a sex? on top of that it's not going to know it's sex for 4 weeks+? So 1 seed will know it's sex the second it's pollinated and another seed is going to magically flip flop sexes based on conditions? I can't believe that until I see proof, scientific proof where someone actually takes some gunk out of a seed and tests it's hormone levels, or whatever they need to test.

The whole feminization process seems to make the environmental conditions hypothesis dead in the water, BUT Nature is weird, and she doesn't always play logically.

One example I will bring to the table is my own experience with Grape Stomper OG, I have read that a bunch of folks that grow stomper seeds get a bunch of males. Other strains are known for producing more females in seeds, some produce males very infrequently. Personally I hit 4/4 males on my first run of GSOG's, now I have ran Bodhi gear in roughly the same conditions, slightly "worse" actually, and got 1/1TER 1/1BT male to female on both strains I popped, the GSOG's were kept cooler and vegged only under blue light (250 MH bulb vs. 6500k CFL for 12 and 250watt HPS for 12 ). Now in the"worse" conditions(as far as producing females goes according to the hypotheses) one would expect to get 3/1? maybe even worse, but to get 50/50 in "worse" conditions when 100% was the case previous? to me that says it's A) the genetics of the strain B) sex is predetermined the second the pollen hits the pistil. You might say 8 seeds isn't very many, you're right.

So a brief recap, the GSOG's were kept cooler under blue light with more air movement and 4 were males 100% balls everywhere, the Blue Tara and TER were vegged in a slightly hotter veg cabinet and moved into my flower space to save a bit of power at night. The ones that were on hotter conditions and under a 50/50 mix of red and blue light came out 1:1 male:female.

If environment played a roll then we have to ask ourselves why did my seeds in slightly better conditions come out males? Why were the seeds that were flip flopped between light intensities, which no doubt causes a little stress the first few times, come out female.

Let's say Burtybob popped 50 seeds and got 45 females, another question is why are those males males? If the conditions are perfect and you have 90% females why did the few turn males at all? and the biggest question of them all that needs to be answered if this is the case, WHEN? when does the sex get determined and how can we manipulate that time frame to our benefit?

It's better to have an idea of something that might work then no idea at all I suppose, but it just seems like another myth to me.

Sorry for gunking up your thread smokylungs :) LOL What the fuck thread am I IN !!! :) Whoops. Thought I was in the last resort seeds thread lol

With as much money as has been poured into the legal pot industry, it's hard for me to believe that someone hasn't looked into this.

Of course, if the goal is to avoid males, they have these beans called 'feminized' that are kinda neat. :weed:

I think the fact that you can manipulate a fem plant to change sex through conditions ams stress is something that shouldnt be overlooked here. Its obvious the cannabis plant has the ability to produce male and female hormones... looking at it from a nature "survival" angle I see this as a way for the plant to perform natural selection.


It would make sense if plantA had worse conditions than plantB that plantA woukd be more environmentally suited to be a male when it comes to survival. Males finish sooner thus needing less nutrients.


A female plant however has a much much longer journey to pass offspring. The time we get our flowers isnt even enough time ti make seed sometimes!!!

My thought is that sex changing of cannabis is the olants way of assuring survival.


As far as Ggog going all males and etc. etc. that is all heredity. There are plant genes out therw that can weigh the scales towards one or the other of course, but i believe that variable still exists.


Inbreeding may be a part of these strains that supposedly give off so many males.... but ive never had such bad luck (or good when im breeding)

I use Hortilux HPS for veg + get more females than males...
Certainly it's luck of the draw, how could I get more females under red light?

I'm no dr but I call bullshit... I think seeds are predetermined, luck of the draw....
I agree. I veg under halide all year and pop beans all year and have been doing so for quite a long time, hot or cold. Its always a gamble. Never seen a pattern of more females with cool temps as opposed to hot temps. I could pop strain A and strain B seeds in the same environment/same time and get almost all males from one and all females from the other. Or a healthy mix of both.
