What causes a garden to produce 75% males??

[cwesto]

I gro in soil, under a 400w MH conv. HPS ballast. I used the MHconv. for veg, and now have switched to the HPS for bloom.

Anyways it is now day 6 of bloom and i am left with only 2 girls, out of my original 8...... and i think one of my girls has a couple of male flowers on it.. woopty doo Basil..

What in the hell caused this piss poor ration?? I am almost certain it has to me my fault, but i dont kno what i did....

This MUST not happen again.

Well most of it just has to do with genetics i believe, but some things that cause plants to hermie is letting light get through to the plants during their dark hours ive heard and maybe a few minor things here and there, but for the most part in my experiences its just the luck of the drawl. The 5 plants i planted, i only got 2 fems, sucks but hey better then none

Probably piss-poor luck more than anything you have done wrong. I know that higher temperatures, overbearing nutrient regimens, etc., and so forth are rumored to cause a higher male-to-female ratio...but I don't know where to separate the rumors from the facts.

I keep my growroom temps roughly in the mid-70's (by estimation), try to be conservative with nutrients, and am careful not to overwater...and many times I still come out with about a 60/40 percent of females-to-males. Sometimes I seem to have a stroke of luck, and it's more of a 90/10 ratio. Sometimes it's a 50/50, or less. I'm sure there are ways that you can theoretically influence the numbers of females produced, but I'm not sure how much of that has been validated...and how much of it is just hot air.

ok cool, thats a good start. Anybody else have any ideas, facts, input, advice???

Lets get some brainstorm/critical thinking going here

[SMOKIN A WHILE]

It's all really just luck. I planted 10 skunk #1 seeds. 7 germinated. All 7 are female after
switching to 12/12 took 3 weeks to tell. I hope I have enough room to take advantage.
So I didn't do anything special I'm chalking it up to luck. I should have bought some lottery tickets.

Ahhhh! I'm SO GLAD you started this thread! Personally, I've had damn good luck, on my 1st grow I had 4/6 females, 1 went hermi though. 2nd grow, 4/4 females....and dare I say it, no hermi's yet. :wtf:

So, other than hermi's, (Herm = light leak, usually) I really think it's just luck.

I've been wanting to explore this too:

Can you (environmentally) influence a seed(ling) in any way to change these ratios? Can you somehow change a 'female' seed into a 'male' plant?

I don't think so. That sounds, honestly, dumb.

Other opinions?

I started with 10 ended up with 6, like everyone says its a crap shoot.

Piss poor luck
Piss poor genetics
Stress induced anything - Overwatering , Lightcycle interuptions , Light leaks , Heat stress , anything stress related is voo doo .

A combonation of any or all these things play a part in these mishaps .

I did 3 packs of 10 seeds from Hygro Seed co. bk in the days of Overgrow . Masterkush , Powerplant , Bubblegum . only got 10 female of 30 - I was bent .

Hey I was wondering about this. I once got some medicine and it had 1 little tiny bud that had literally (I counted) 15 very viable seeds. It was the craziest thing I never did see. There was not a one seed in any of the rest of it. Not a one! So did this plant happen to polinate itself? If so are the odds very likely that they are all feminized? How likely could this be?
