Longer veg = lower chance of herm?

Saw someone hint at this one time, wanted to toss it out there for folks to chime in on.

All of my grows thus far that have made it to flower went about 45-55 days veg under 55w 6500k PLL lamps. All of the plants were pretty short but bushy, even the Neville's Haze (stunted start though). So I didn't worry too much about height because the initial flowering stretch should not be able to overcome my limitations. At 45-55 days all had pre-flowers.

I've since switched to a 4000k 150w CMH lamp. The plants were still growing with tight nodes just like my previous vegs under the PLLs, but now they've taken off and are growing like mad. This means I may not be able to go 45+ days again because this may be a problem in flower due to overall height. I've got two plants at 32-33 days above soil and I do not see any pre-flowers yet.

This long intro was to ask this: do you think that vegging until at least the appearance of pre-flowers contributes to the stability of plant in flower? That is, less likely to herm than plants vegged for a much shorter time or 12/12 from seed?

imo NO , folk flower plants 12/12 from seed with no issues

i know it is possible to cause plants to hemmy via stress, but it is not easy to do it with good genetics
over the years i have only done this 1 time, and i am not sure what i did think it might of been heat not sure what it could of been

some plants genetically have the tendency and you can bring it out with stress, but it needs to be repeated stress over time and the right kind of stress

if it was so easy to make plants hemmi and produce pollen via natural stress, breeders would not need to be spraying plants with colloidal silver or silver nitrate to produce hemmys
they will not turn hemi overnight so to speak, just because the timer did not turn off for 1 night and they missed 1 dark period etc etc

most hemmys result from fem seeds, and poor control of genetics by breeders, NOT GROWER ERROR imo .. obviously breeders and fanboys will not agree with this statement

in almost 20 years of growing plants i have seen very few hemmys, i never buy fem seeds but do grow out the free ones from time to time

weed plants are strong and can handle a huge amount of stress, they can be cut back to virtually a stump , they will regrow
they can have all there roots cut off so only a few remain, they will regrow, and will NOT hemi as a result of this, they can be abused
i have never thought of a weed plant as being anything other than very resilient and vigorous

if a plant hemmys early on, it would have to have this genetic trait for it to do this, rather than throwing a few male flowers at the end of the flower cycle
in theory fem seeds can produce excellent plants and do, there is nothing wrong with fem seeds if they are produced correctly
avoiding phenotypes during selection that show hemi traits early on , some breeders take time and care to do this, many others do not
which results in strains that have a greater tendency to hemmy and lots of unhappy customers

i think some seed sellers are just cashing in, others have good intentions and do try to keep control of the genes but make mistakes
it is very hard for a breeder to admit there is any hemmy problems and he has made mistakes, being honest is not good business policy here

for a breeder to admit his strains have hemmy problems would basically be like saying "do not buy my seeds"
it would create a panic among noobs, who are always worried about hemmys anyway , they constantly fear plants turning hemmy overnight
it is only logical for breeders to blame individual grower error imo admitting the truth will lose them money .. its very easy to see most seeds are bought by noobs
the most popular selling strains are fems and cup winners, they have to constantly keep coming up with this shit to keep them buying what they think is new and the next best thing

peace good luck
