ALL MALES......what the hell???

just wondering if anyone knows if getting all males is just bad luck or did I do something wrong? Is sex pre-determined before germination or is it caused by environmental conditions?
- I planted 8 seeds, all of which germinated within 12 to 24 hours
- used promix bx
- temps 20c to 24c
- cfl to veg (3 weeks) then switched to 400w hps for flowering
- ph was a bit high in the begining but was corrected
- all 8 turned out male
if anyone has any input i would appreciate it, i am starting all over and certainly dont want to waste another month

hey man! as u can see by my post count i am no expert, actually just waiting for people to help me with something, but im pretty sure sex is determined all ready i read recently sumwhere that stress can cause hermis but i dont even know for 100% if thats correct, but im guessing u were just extremely unlucky but thats just a guess, why dont you try order some fem seeds to be extra sure nxt time, they bit more expensive but at least u have some guarntee, its not always 100% that u get all females but i bought a pack of 5 fem isis seed from dutch passion an 4 were female i killed one from being a noob (was my first grow) so cant be sure if that was fem too or not but 4/5 aint bad!

You just had some bad luck my man

with reg seeds you got a 50/50 chance on them being male or female

out of 8 seeds you should have gotten at least 1 female ( damn )

bad , bad , luck

there are ways of increasing the chance of fems.........i do 12-12 from seed which seems to produce more fems............you had some real bad luck there mate...........i got 26 regs in now so will let you know the count of males........ive read that temps light spectrum,feed all can play a part but im no expert..

hotter temps will get you more males....seeds anyways

how long after planting did they all go male? Did you stress them? replant them? I have read... not sure how reliable... and (tested it myself) I have frozen seeds (quickest method?) BHO them for a sec ... I again dont know if this is 100% but... I have had VERY few males (growing mids orange crush) again... not 100% set yet on this... but the logic is there in a round about way...

When I grow ffof I get all most all females but you also get a lot of low ph and burn issuse

I don't think it's anything but luck to be honest. I had a friend germ 12 seeds and ALL of them were females! I wouldn't say anything about stress, lack of lights, or heat, because his grow room is in the upper 90s. He uses only a few cfl lamps, and he even dropped a few and broke them. They still all became females even with all the stress and everything. So, I think it's all dumb luck.

Better luck next time dude. Luckily you didn't pay for the seeds, right?

Yeah, i'll put another vote in for 'crap luck'. I've read about a stuff about growers experimenting with ways to influence sex, with regular seeds, but none of the methods showed any real advantages/disadvantages. So far, from what I've seen, the genetics are there from the beginning, whether a seed is going to be male or female, and it's near impossible to change that. Try again, my friend, the odds are in your favor, now....lol
