Ah thanks for that... here are my 2 pics from the 1st post. Maybe i will look into checking that (again though have been running the 1kw for years no problems) - i do have pretty decent airflow around my plants - would this help keep leaf temps down or does that not really affect this kinda heat? (also could rest my nuts on my 1kw glass its that cool)
Unfortunately RH is one of the things im not maintaining atm pretty much sits about 20% nowadays (was about 40% during veg from memory), for veg i do a bit of foliar misting if the RH is too low but cant say i have ever had RH issues in veg or flower yet (not to discount it though)
Pic 1 is example of all the hermies i had by week 1, pic 2 is the one i thought was female but self pollinated to the max with a few external nanners but i suspect majority are inside the buds (thankfully)

Okay I have a lot to say about this, wow.
For starters--do you have more pics of the "hermies"? The angle on this one doesn't really show the pre-flowers well enough to make any kind of solid determination as to what we're looking at.
Beyond that we usually want to see much more than pre-flowers before saying something has hermied. I mean if you had shit get pollinated then obvious something is up--but your pics aren't giving us a good idea of what's going on. I see no anthers in this photo.
The 2nd pic, again I don't really know what I'm looking at. Looks like a normal female to me--do you have pics of the actual seeded plants?
For having been pollinated that bitch sure is reaching her pistils out to the max--this doesn't seem super normal to me either. More pics please (just put up all the pics you have if you would).
Now, the humidity. Holy crap dude. You absolutely
cannot run a strain at 80F and 20% RH. If your other strains are doing fine its because they are
totally beast.
Your vapor pressure deficit is like in the 30s or something (it's literally
off the chart). Generally speaking you want a VPD between 6-12 for a wide range, and 8-10 for an ideal one. This is a problem is the nicest way to say it. This combined with what several folks are identifying as a high EC is a recipe for absolute disaster.
I've just spoken with my botany master's student buddy again and he's surprised the plants were alive
at all. It's no wonder they would hermie and try to make seeds (this is what a dioecious dicot does when it thinks it's going to die before it reaches maturity-that is essentially the entire reason why they do this).
If you pay attention to nothing else when you grow cannabis you need to pay attention to the temperature and the RH. Honestly 80F is pushing it, but you can get away with it if your VPD is reasonable (or if adding CO2). At that temp this means you need an RH of between 60 and 70%. This is really why we like to see the temp closer to 72-76, at these temps an RH of nearer to 40-50% is okay, and that's really what we want to aim for in flower to avoid mold and bud rot (especially in late flower).
Even if you never run LAD again, you need to address your humidity issue. You are shitting on your quality and yield in a big way by failing to do so--and I'd wager your EC + lack of transpiration would force a hermie in at least half of the world's genotypes based on the analysis of my botanist buddy.
I'm not trying to jump on ya dude, but holy crap--for yourself you need to address this.
It kinda confuses me that you would overlook this, but somehow feel comfortable enough to rule out environment as a factor in the hermies. I'm not saying you're being disingenuous because I think you've been really forthcoming throughout the course of this thread--but you've got a lot to learn yet before you can make determinations like that if a 20% RH isn't setting off alarm bells in your head.
20% is the average humidity in my room when i ONLY heat (to around 75F) and I intake outside air during winter. That is to say it's about as dry as things can get if you're not in the desert.
You'd have to actively try to make it any drier in there--and that with plants in the room!!
Buy a humidifier, immediately.
All that said, there's still some anther-action going on in the rest of this thread and so there is some credence still lended to your initial idea that it might be "hermie prone" as a strain. However I think that at least for your experience we can amend the original language to suggest that it is hermie prone under
extreme stress.
Even with the wonderful growers who are posting their anther experiences with this strain (and others)--it makes me wonder if they didn't have a "too dry" or a "too hot" day as well. I don't want to call them into question because this will probably just start another pissing match and its not worth all that drama, but I have my doubts at this point whereas before I was starting to see a bit of a pattern forming.
This really has called the entire thread into question for me. I mean that in the nicest way, of course, but--just wow dude. My jaw is officially dropped open.
I wouldn't even
DRY bud in 20% RH (or 40%, personally)--let alone grow it. Really really surprising.
Good luck with the rest of what you've got going. I really suggest you deal with your RH, perhaps lower your EC a bit (I can't comment with authority here though I must say), and run the other pack of LAD. I think your results will be much better under those circumstances.
