Increasing your odds for females

I've been reading Jorge's cannabis encyclopedia . Has anyone had any luck with increasing their odds of female plants from regular seeds ? In his book he makes several recommendations.
1 shortened light cycle for the first couple of weeks
2 cooler temps
??

Nope.

Seeds are naturally random in male to female ratios because that's how nature intends it. If there was some advantage to have more of one over the other besides human greed it would have done so however its just inificient and the species will try to make as many seeds as possible. Usually the ratio is about 50/50.

I have heard these rumors but never really knew.
Alligators eggs can be determined by temp, probably an evolutionary reason for that.

Makes me wonder under what circumstance weed would find it favorable to allow outside sources to determine sex.

Or could it just be an accident.

Same here. Very much.

Well one reason for this could be that alligator embryos are not fully developed embryos in the egg state however (viable)cannabis seeds are fully developed when coming off the plant. One factor to keep in mind is that seeds will produce hormones in the case of a bad season and this is why cannabis sativa will produce hermaphrodites in order to have the highest pollen and seed ratio possible to continue the species. aside from that i've never seen any conditions where someone would be able to produce a higher amount of females in a consistent manner.

I've read here and in other places that optimal conditions can produce a higher female to male ratio. You cannot actually control which is which; there's no unicorn here. But you can make your conditions optimal to increase likelihood of females. 50/50 is the standard but how many times have you got more boys than girls? Too many probably. There was a study put out by Dutch passion where they found you can increase your f to m ratio by keeping temps relatively low, providing optimal nutrient levels, using proper light spectrum, optimizing humidity, & shortening light times. Not sure how accurate this study is but I know some grow books (can't remember which ones) have cited similar findings.

Lol, i was actually alive in the hay day of weird pot science/myths.

I remember my uncle going on about carrying seeds into the xray with you
To get them poly.

Then then it was microwave,

Then there was thc in the roots.

Problem was we all kind of believed
Because the info was passed down from people we trusted.

Your statements are exactly what are in his Encyclopedia. Due to a plant count that i'm trying to stay under I'm trying to improve my odds

I have grown many regular seeds, and did test sonething when I made the switch from feminized to regular. First grow was 10 reg seeds. My humidity was 30-40%. Out of 10 seeds I got 4 females only and 6 males. Then I heard that raising humidity levels increased female ratio. Next grow I was at 60-70% humidity in veg. Planted 10 seeds and got 7 females.

Is it because humidity? Maybe. I think it was a coincidence. But the results speak for themselves.

I will keep testing this, the growshop guy swears by it.

Thats the problem.
Germ rate has a plus or minus of probability.

I would have to see the results repeated a shitload of times.

Not devaluing what you are saying
Just that it would be hard to prove without taking great pains

Total unicorn but....

It has been observed that in the wild in the bad years more females occur than males as a survival strategy of increasing the chance of closer proimity to males and chance of fertilization. Add in the hermie trait and this now becomes one fuck off a survival strategy.

Still no one has managed to do this and it takes a few bad years for it to show.

Again this is a six legged polka dotted unicorn for us growers :-)

A touch of clairification there is a lower limit of about 55 deg f acording to the report, this matches my experience.

Question
What If a breeder were to have seprate environments to select males and females. Considering if uou get a male from an optimal environment would it be an ubermale? And likelwise a female from a subpar environment would be an uberfemale? Would breeding the two have any benefit.

I agree that this should be tested a lot, lot of times to get accurate results. My experience was probably a coincidence. We as growers can only provide the best environment and let them do their thing. Its not possible to get conclussions from two grows.

I have seen many people on youtube claiming a volcano shaped hole in the seeds will get you a female. Everyone commenting in that video says it works, ;/.

I dont think anything about this is true but it doesnt hurt to raise hunidity levels to 60-70% when at the seedling stage.

The fact that I can chemically alter plants leads me to believe that it is not unthinkable that someone could figure this out.

I agree, the cannabis Community is learning more and more each day about this plant. I'm new on the scene and have NO idea what I'm doing. Kinda like cooking a recipe and adding your own touch..... You hope it works out.
I've dropped to regular beans, that's all I have room for. I'll put them under a "blue" veg light under cool temps. Let's see what happens
