this has probably been brought up a million and 1 times b4 but i havent seen a thread with this.......yet!

anyways i was just reading strain reports/growers reports with ppl who had high male ratios when planting(i went overgrow strain base-theres loads!).

it seems from reading through quite a few it seemed vegging under big lights had a lot to do with it....maybe it is concrete that a majority of strains like low temps whilst in veg....maybe being the most determining factor to getting more females?

who knows....but i read and read and read and most of the growers with 400w in veg and above were getting less than 50%......!

sometimes it can be a tad bit confusing because there is a growing army that say seeds are genetically made up already.

that puts all that more blue spectrum/low temps/high n uptake to bed as a load of rubbish then.

i doubt it.

i keep going everywhere over the net and seeing ppl who stress plants to bits from seed....way b4 any sexing shows...and they come up with good fem rates..?
how?

i mean i could sit on one side of the fence and say blue spectrum/low temps/high n uptake whilst in veg gets me high rates.
or i could sit the other and say its all genetic....and im taking pot luck with seeds and its nothing to do primarily with the enviroment.

see where im going?
there is so many contradictions to whats concrete in growing.....

sometimes you have to step back....take in all youve read....and make your own judgements with the conditions youve got.

peace.

and dam,...... this getting high fem rates from standard seeds is where im next exploring......if it goes tits up then at least i can say i took all comments on board...and didnt listen somewhere.

Hmm Yes

well i used some methods for higher female ratios. It seemed to work...i veged/am flowering under a 400 watt hps. I started with 6 total plants 2 went male 1 went hermie.....not too bad thats kinda over 50 percent. I kept temps down between 72-75 a lot from mid veg all the way till now.

Wow....that's a new one for me. That would sure make growing outdoors impossible. I have never experienced the phenomena....actually even had 100% female grows under much more than 400W. I use more than that now.....hmmmm wonder why they would even make an MH bulb over 400W if that were the case.......

Here's another one that I read recently

i was leaning towards more the high temps probably causing high rates from the big lights.....not the big lights themselves.

its all well and good having a 400+light in your grow for veg...they make em...but that doesnt mean your going to get high ratios using it.

from what ive seen.....i wouldnt use a big hps/mh in veg...period.

but thats me.

There was another REALLY long thread about what you can do to increase your female odds, but I couldn't find it.

I think that humans are just obseesed with trying to have complete control and prefer the idea that our input effects the ratio, its all genetic just like every other species on the planet that i know of,

The only way to increse your fem rates is to use clones

That's an interesting observation.

For a long time I have vegged under MH almost exclusively, always 400w or higher, and have not seen an unusually high number of males on average. I would guess that it is probably related to heat.

well according to that "higher your female ratios" thread it is in fact a heat problem. They say as a main point to keep your temps more down from 70-75...75 being optimum rather than 80+ which most people in warm climates seem to have trouble with. Considering the cold air i have going in the room heat isnt usually a problem. Also i think stress is more apt to produce males if not hermies....the 2 plants i transplanted late/ put through the most stress turned male

I always grow in winter were temps r 65-75 and always get around 95% females. Last year I tried growing in summer temps 85-100 and got 20% females. I grew with 400 HPS in soil. Never growing indoor in summer again.

My personal grow observations on the subject are - I believe that environment (temps, R/H, avg. soil moisture, etc) play a roll in things. The plant doesn't declare sex until wk 3 or 4. Added environmental stress around this time can adversely effect m/f ratio. Keeping my plants out of stressful conditions has seemed to help.

When I've had rough vegging conditions (maybe a couple of late waterings, high heat, low R/H) I have noted high male ratios. I have noted the opposite as well.

There's certainly always the chance of coincidence...but with each grow, the data so far... has supported the theory for me.
