Hi guys/gals,
I have real issues at the moment with Hermaphrodites/ seeds. Last year 3/4 of my grows came out seeded due to Hermaphrodites.
Grow 1 was my first and I stuffed it up on every turn yielding about 4 ounces of seeded crud. Second was nice seedless smoke, I had stressed this out as I was inattentive and allowed the roots to bind a little. They came back well.
3rd I got sick in the middle of and almost had to switch it all off as I was taken to hospital. It came out seeded and I had dealt with fungus gnat during that one. Probably some of the worst smoke I have ever indulged in, ended up cooking most of it to nice results, ( maybe you can make a silk purse out of a sows ear.)
This current grow was the one I held out hope for. I grew it under a scrog and it bloomed well, the tent is full of buds bursting at the seems, BUT...
Yes I snuck a smoke last night and SEEDs again.
I tried everything to exclude shock, refrained from trimming shade leaf etc. I also have trouble identifying the Hermaphrodites.
I grow from seed, ( white widow, ) use a 600 w hps in well ventilated tent.
Could it be the seed? Could it be temp?
Please, I need help?

It's the seed. Stress can play a factor, but only extreme stress; so not likely. it's their genetics.

And sounding by the quality of smoke. I'd ditch that line altogether. Pick a better vendor/source.
I bought some hash plant from Gypsy and it was horrible greasy smoke and did the same thing you describe above, went hermie seeding everything with unusable seeds. restarted with making my own seeds with line from mandala seeds and good bag seed.

Anyway sorry to hear it, got keep on truckin'

Some of the most potent lines are prone to bananas, which is why they are used, but others have managed to make potent lines without that predisposition. Like intrinsic says, find one, if finding a few seeds is problematic for you. A *few* seeds in my smoke doesn't bother me at all, in fact I rather like it.

Were all the hermy grows from the same seed stock/line? I'm assuming you didn't grow out the first lot of hermy seeds . . .

Yes I had thought it may be the seed stock, but you know, NEWBY and all that jazz

Yeah I tend to cough far too much on seeds. Waiting for my eyes to blow out of the front of my head from coughing on seeded weeds. The visuals are interesting though.

Erm, yeah, nah, I mean yeah you assumed wrong. As soon as I read this post I took my palm to my face. I had thought that seed was fine and that it was all down to my inexperience.

So in short thank you for all your answers, I really do appreciate them. I'll start looking for a seed trader and return to the proverbial drawing board.

I can't said this about all my plants that went hemi seeds did .. Sour Diesel went hermie and its seeds were hermi to.

Butt most hermi plants I've had the seeds weren't hermi. They tended to be female.

Hermy seeds grow hermy plants. Marijuana 101.

All cannabis has the potential to turn hermaphrodite, but genetics will determine how easily it does. Some strains require a lot of stress. Some very little. Some none at all - they will turn when there are no other males around.

I had a lot of fun doing this grow though. Turned out only the 1 plant was full of seed and it made for good baking material. The yield of 730 grams of bud was a true reward. It was the first time I had used a Scrog under 600 hps. I am rather chuffed. New seeds, new grow lets see what I can produce this time. Oh and a new vented hood so maybe I can get it better yet.
Again thanks for all your help guys.

I had a few male flowers appear but they were not very fertile because I have only found a couple seeds, but I had something much weirder happen. I took clones of all my mothers and then chopped the mothers. I went in this morning to water the clones and 3 different just rooted clones which were not hermies before were peppered with male flowers. A widow and 2 different amnesia haze. I could have mislabeled one but not three. Could it be the pole shift? Something odd is happening.

Yeah, a bit weird. I take it you're flowering them under 12/12? Or are they going hermy under veg light (18/6, 20/4 etc)?

When you took the clones, were the mothers flowering, or just starting to flower?

They were mothers under 24/7 1000 watt halide, then the clones were placed under cool white LED 24/7 ,after 10 days they were rooted enough to transplant to cups, that was about a week ago and put under 600 watt halide 24/7. Maybe they need a nap now that I think about it. Female flowers are visible on the rest of the clones and one has considerable trichomes on it.

Have you always kept your mothers under 24/7? The clones look a little stretchy - is it hot where you are? Light and/or heat stress perhaps?

Plants do need a dark period to transport and use sugars (starches) produced from photosynthesis. Stored starches are used for active transport of nutrients during the dark period. When there is no dark period, plants will self-regulate photosynthesis, turning on and off to compensate. It's a bit like "micro sleep" for plants. The need a couple of hours of dark at least.

I once experimented with different veg photoperiods and found the one that appeared to produce the fastest growth was 11 on/1 off. I still do it sometimes, otherwise I'm usually on 20/4 or 18/6 depending on how I want to regulate growth. Sometimes I actively slow my clones down when I have too much time in-between flowering cycles. I'll give them a light feeding regime and turn the lights down to 18/6 or sometimes 16/8, just to prevent them from flowering.

The 11/1 light trials weren't very scientific, but the difference in growth was noticeable, anecdotally.

It has been hot and I don't usually leave the light on all the time I just got lazy but since going under the 600 watt the distance from the light was the maximum I could manage so that might cause a bit of stretch plus they are mostly sativa. They definitely got some stress. I do need to slow them down so I was thinking about putting them in a fridge for a week at a time and then giving them a day or 2 of light.

Can't you just buy a cheap timer and set the lights for 18/6 or 16/8 and run the lights during the coolest time of day/overnight?

I have timers. It was pure laziness. If I see some pollen I might mess around a little with it on my outdoor.

Are you talking about using pollen from hermies? Do you really want to proliferate the hermie trait? The male is very important in the lineage and not a good parent pick if a hermaphrodite. Personally i wouldn’t.

The one plant was flowered twice without any sign of herminess and only after extreme stress did it express that trait so I think it could be good for an outdoor seed crop. I wouldn't try to sell it to anyone or anything like that but as an experiment sure.

Well it will produce fem seeds but your yield will suffer from it. If that doesn’t bother you and you just want to play then go for it. Just know that seeds that get produced could have that trait as well. That’s why most reputable seed makers employ chemical methods to produce fem seeds. Have fun......

Entirely up to you, but the easier a plant herms, the less likely I would be to use it.

A build-up of ethylene during the dark period causes plants to flower. Using colloidal silver or giberellic acid inhibits ethylene production which forces a flowering plant to develop male stamens - the techniques used to "self" a plant to produce feminised seeds.

You can see how light leaks and photoperiod now both disrupt ethylene production and that is what causes a plant to herm. That's what we mean by "light stress". It is the reason why it is the dark period - not the light period - that determines flowering cycles.

A plant's ability to continue to produce ethylene, or resist the breakdown of such hormones, is what makes it more or less susceptible to herm. It's obviously genetic.

If you want to use pollen from such a plant, go ahead. But I would never trust the progeny in an indoor growth. That's just me.

I agree 100% with everything you both wrote there and these seeds will be sown directly outside. My only interest would be curiosity.

By all means have fun, hopefully no one around you has plants going as the pollen can travel great distances if conditions are right.
