What type of Herming are you seeing? A shitload of male flows, a bunch of pistils during vegging? The current genetic situation is pretty shakey with a ton of unfavorable traits sneaking in with the wanton hybrids being thrown out there. I have to admit that you have a pretty steady track record of having hermed plants... I might find a single male flower here or there on a 7 ft plant,but I've never had any issues like you are having. I have noticed most of the newer strains throw pistils during vegging, but that is different than a herm. Do you have any heat sources that could be giving off IR? Aside from stress and light leaks, I don't know of any other reasons for it other than genetics... but I don't think that the seed vendors you named have poor products. It has to be something in the environment. No power indicator lights?
I don't think that your nutes or watering style have much effect, unless you are getting a little salty, but even that doesn't usually cause herm issues. This is a stumper! Any chance of getting some pictures?
If i keep my 2 600 hps flower room at 27 celcius (80 farenheight) for extended periods it is too hot and causes leaf stress and hermies sometimes.
My room likes 77-78 under the lights max.
It’s probably genetics .
Ah, this is interesting. Now I'm wondering if I should drop the temperature to 25C (77F) on the next grow.
Am I really that unlucky to get shitty genetics with 6 different strains from 3 different vendors though?
If its one breeder'stock ok,looks like its the genes.But if it happen every time with lots of different strains and vendors common sense say its in the enviorment/feeding........But hey who knows may be you were really,really unlucky?!:)Wish you luck next time!:)Am I really that unlucky to get shitty genetics with 6 different strains from 3 different vendors though?
Is there any chance light comes through a vent when the exhaust kicks on or the corner of a zipper if not tightly closed. its got to be a light leak with so many consecutive grows getting hit. I've got 6 hermies myself finishing off next week. I blame it on my dehumidifier's little blue fking light. 2 nights before I caught it. Can't see the little light during lights on but lights off it lights up the room, I usually have it covered but just left it off for 2 nights and it fked my crop.Just finding a ball or two (definitely not calyxes) amongst most of the female flowers. Inside the balls are like bananas. I've found a couple that clearly have pollen inside. I've been going in there every night and picking them off as I see them as I absolutely cannot afford to throw the whole crop out.
Absolutely nothing giving off IR. The heater in there is one of those flat, see-through things, can't remember the name of them. The door and the entire room is properly sealed, and there's no kind of equipment in there giving off any light (other than the actual lights). I've actually stood in there before for 20 minutes out of desperation just to check.
I'd have bet anything it was a genetic thing after the first 2 herm crops as it seemed like too much of a coincidence they hermed after getting seeds from a new place, but now I'm just convinced something else is going on. But you're right, it's a real stumper and we're just baffled as to what's causing it.
My lights come on in about half an hour, so when I go in to check, I'll see if I can find any more and get a picture of them.

I've ranted before about the current genetics and loss of most real landrace strains, but I don't think anyone could be as unlucky as having hermed plants from different strains and different vendors... with that kind of luck, you should avoid the lottery, etc! AFAIK, light leaks during vegging shouldn't be an issue because the compound that causes the plant to flower is deactivated by light... so extra light should inhibit flowering, and herming, at least in my warped way of thinking. In the many years that I've been growing, I have never had a hermed plant, although I might get a sporadic male flower that drops a couple of seeds, but I'm talking maybe 2 flowers on a 7-8 ft plant, sometimes. I don't think I could make a plant herm if I tried.
The only other thing I can think of is something that you re feeding or using somewhere in your setup. Light leks seem to be the major cause of herming, but I still don't quite understand why. Some compounds, like silver products, will cause pollen sacks to form by their effects on ethelene.... you aren't using a home brew CO2 bag or anything that could give off etheylene or anything similar?
Indeed... a real stumper.
I've read a couple of things you've said that to me are not normal.This is why I don't think it's entirely a genetic thing in my case. There's just no way my luck can be this piss poor.
With regards to your feed comment, I'm using the Biobizz schedule (clicky link in my OP), it says to use Fish-Mix during the first couple of weeks, then swap to Grow when you switch to flowering. But I straight up use Grow from the start during veg, although I've googled about this and it seems others do the same. Only other things that get added to the feed are calcium and pH up/down.
Oh gosh no, nothing like that. But now you have me thinking... In my grow room, it's not a tent, but a purpose-built room room. The lining is silver reflective material, kind of like that reflective garage insulation stuff, kinda looks like silver bubble wrap. The room is relatively big, so of course there's a lot of it. Would that have ethylene?
Do you mind if I ask, are you growing from fem seeds?

Seedlings 12/12? then to 18/6 ?? Why do you do that? I go 18/6 from the start - 20/4 - 12/12 Starting at 12/12? What's with that?
Also why do you need 22L pots for plants 1 ft tall? I finish in 11.9 L or 3 gallon pots. I feed or water until I get runoff and that takes 1 gallon water or feed depending. I find it too hard to tell watering needs with large pots.
I don't ph my input water but I do ph my runoff and check ppm. I think it more important to know what condition your soil is in ( through runoff readings) than guessing by phing your input liquid.
Flowering nutes all the way through grow?
I make my mistakes to my man and I'm just blowing in the wind some of the things that strike me with your growing. I'm not an expert by any means i'm just a basement grower as yourself.
I'm not sure if any of those things would cause hermies but something your doing isn't right. I'd suggest getting back to basics.
Seed
water
light
proper nutes through the stages
18/6 until they reach the size you want
12/12 until they're done
pollen dies within 3 daysMy best guess is that your grow space is contaminated with pollen. If it is a tent, replace it. Otherwise, clean the area and all equipment thoroughly.
