Many led growers who have been using them for years have vegged under all blue or mostly blue lighting many times in the past, myself included. Nothing other than average or the same as white light for male/female ratio.
Just now had Atonic x Apollo f4 from Bad Dog go 6/6 female here under all white LEDs in veg and flower.
Maybe that's why I got mostly males from my atonic x apollo. Vegged with a 3100k cmh. Always used more blue and never got that many males.

Studies found that in the American alligator's eggs, incubation at 34 ºC (93.2 ºF) and above produces mostly males, while incubation at or lower 30 ºC (86ºF) produces mostly females. This means if the nest is laid on a riverbank on the sunlight, the offspring will mostly be males.Sep 25, 2019

This is how I treat all my seeds..
I only pop about 30 seeds each time & get close to 93% females from the seeds
(Some get killed)

I did veg a batch of seed under some t5 HO uv bulbs,damn near all the seeds was male.
Dont know bout light spectrum but I remember subcool sayin this as well-cool temps more girls vs hot temps more dudes

I kind of feel like if this was a thing a Dutch seed bank would have found it out by now. I know that statistically speaking you can have outlier batches and cannot reproduce these effects at will, then coincidence owns the day.
There has to be some studies out their already on the influence of light spectrum on sex. I just havent come across it yet...Interesting and pertinent topic though.

The sample size I have is certainly enough to show a valid bias, and that something is off....although a little small for what I would typically like to choose for breeding..However, "it is what it is" as simply haven't the space to grow more...

What I have also noticed...of the males...3 are definitely Hermie...(Single pistils petruding from immature balls)...

The Tri-leaf seems to be one of the best in terms of overall plant quality of the bunch, but has yet to show sex..I think it might be male, which would be a big help...particularly if it not a Hermie too

Looking forward to growing out some Useful Seeds fems in 2020. Just grabbed 3 packs at DCSE.

Double Dipped Strawberries
Sunny Diesel
Orange Cookies x Choc Diesel
Good choices; I've ran DDS and OC x CD, and Useful is a solid cat.

True,but them sex test kits can give wrong results.
I consider myself woke. I let the plants decide what gender they prefer to be. Of course, if they decide wrong, it could end in the death sentence.

Jackpot!!

I've got a good solid male for my breeding program...Nice solid plant, aggressive roots, vigor stem structure...based on 12-12 cant fairly comment on inter-nodal spacing, or other variables..and no Hermie showing thus far

My Tri-Leaf plant (Whorled Phyllotaxy)...is the Stud...(first snap)...

What make this "Stealth" project fun is the number recessive traits that reside in these f1's...Four!

All contain: Auto-topping trait after first node..(will reconfirm the trait in f2's), Webbed leaf, Autoflower trait Pp (heterozygous in f1's), as well as the tri-leaf component...

My goal, which might be a bit of a stretch, is to pop enough seeds that I create from these f1 crosses to nail down the Autoflower as well as the webbed trait...I'm hoping for 4-5 plants with these traits to get some decent male and females...Target will be approximately 1 in 16...so I'm figuring I'll have to pop 80-100 beans outside to find what I'm looking for come springtime...that said, anything Autoflower will likely be kept anyway rather than culled considering the extent of the recessives I'm looking for

Very pleased how the plants are looking so far..nice thick bushy indica looking leaves.

Cheers
Toad

Thank you for saying that. I've shared my opinion on it in the past, nobody was buying it, lol.

When fems herm tho, more then likely thats on the grower........given decent genetics. Just a tiny light leak will stress the fuck outta some strains. Leaving the plant totally dry two days extra too, that can shock it to herm.

Not sure if the fem seeds comment was referring to my project?

The seeds I am using are not feminized...I made the crosses myself.
