24/7 and 18/6 are proven to work, you don't increase the chance of anything bad happening to the plant. Seems like there is Hermie mania on this board over the past few months. Never heard much about it before and now everyone and their brother has most of their plants being hermies. I think hermies show up more than males do anymore, must be soemthing in the water. The best way to get a hermie is to flower with 10 hours or less of light a day.

My theory on why the world is seeing so many hermies lately is the increase in use of feminised seeds. Nearly every feminised plant I've seen grown to maturity develops at least a banana or two, and many going full hermie in mid flower. A single banana isn't enough to stop anyone's heart (pinch it off and keep moving), but you don't see that happening so reliably unless they're from feminised seeds. Just a theory.
I know 18/6 is as effective as 24/0, I just want to know if light during that 6 hours of darkness increases the chance of developing hermies.. I realize it's slight hermie paranoia but these are my precious mothers we're talking about.

Did you mean by giving plants a dark cycle that in and of itself creates a situation where light may leak into a grow area creating hermis?
An 18/6 light cycle is the most commonly used light cycle for vegging.

I think he wants to know if you grow 18/6 if the increased darkness is going to cause his female plants to turn hermie or increase the chance of seedlings turning into hermies becuase of the 6 hours of darkness.

I you interupt the 6 hrs of darkness in veg, nothing will happen.

That was my question, thank you.

someone said that since mine are pre-flowering during the veg period they may have been interrupted....so i'm not sure what is true
I thought there were less hermie's because of the feminized plants. I dont know....... i have fem seeds and the are bushy as hell

Plants will preflower during veg regardless of light, it'll happen shortly after you see alternating nodes.
Bushiness (or lack thereof) has nothing to do with the hermie trait as far as I know. There's no way feminised plants could yield LESS hermies, but I'm talking about plants turning hermie for no reason, as in no light issues, temp issues or stressors like that. It's just been my experience recently that femmed seeds produce more hermies.. I figured that since femmed seeds come from forced hermie females that it might not be coincidence.

You run a higher risk of hermies in flower if you put them in 12/12 before mature or light interuptions on the dark 12. In veg well that could be stress or bad seeds?

I've seen five of five greenhouse seeds feminised white widow show some level of hermie under what I'd call near perfect conditions, but I can't yet rule out bad seds.
However, I just met five feminised paradise seeds white berry babies that will live their lives under the same conditions, so we'll see how they do.
My closet is well constructed, this is not environmental stress or light leaks. The ww's were vegged for exactly four weeks and they were all showing preflowers by then, so I think we can rule out premature cycle change too.
I think it stands to reason that since the parent is forced to hermie before the seed is created, there's an increased risk of getting hermaphrotides from the seeds.

Good Post.
Hmm had preflowers on it, so it was mature. You had the optimum conditions too? Hmmm.
You vegged them for 30 days saw preflowers and went 12/12 had 5 herm. Are you going to flower the white berry after 30 days? How tall where the herms when you went 12/12

I'd guess the ww's were about 30 inches tall when I flipped the lights and they finished around 3 feet. Note though, that while they all had some hermie traits, the one I ended up cloning for motherhood produced only a banana or two after flowering for almost four weeks. The most extremely hermied had male flowers at every bud site much sooner in the flower stage; the other three plants landed somewhere in the middle. I let four of them finish and got a satisfactory yield.
I'm not going to veg the white berry ladies for any certain amount of time, I want 4/5 of them to get as tall in the veg cabinet as possible before I put them in the flower closet. The fifth is going to be topped into a bush and left in the veg cabinet.

Sounds like you did not rush them, they had there heigth and maturity set before 12/12 .
Did you 12/12 to sex then back to 18/6 ?
I just don't see how you could get so many hermies?
You didn't pinch or top in 12/12?
There was a post a few days ago where a lady put 4 in 12/12 and top one in there a week later. Well it went hermie and the others where fine.

No pinching, pruning or topping of any kind was done to these particular ladies after they started 12/12. I did cut quite a few arms off the week before flipping the lights, my cloning is unsure so I took more cuttings than should've been necessary. I've never heard of that kind of injury being a stressor as far as increasing risk of hermies, I've topped other ww's into complete bushes while in veg and they didn't hermie. I suppose stress is stress though.

Well I have done the same, not so many clones at one time, but I do take cuts 1 week before going 12/12. If you took lots of cuts per plant and they all stressed into hermie? Well still it's hard to think that they all stressed into hermies. That's the only thing you really have to go off of. I mean everything sounds like it was at it's best?
I wonder if it was over cutting at one time?

Just take 1/2 of what you did, wait a week and take the other half. But yeah you need to figure out what happened.

The plants were vegged to 30 inches (2.5ft.) and they finished around 3ft. (36 inches). That is amazing to me since most plants will double to triple in height during flower and yours only grew roughly 6 inches (1/5th of an increase in growth instead of doubling to tripling as is normal).
