What causes herms?

? Guy Fire-y ?
What a great thread! I've never had issue with the timers but I'm using cheap ass indoor timers in greenhouses and somehow getting away with it so haven't thought about it.

This thread has led me looking at other options specifically made for outdoor use. I'll know if there's a failure pretty quick but I'm really liking this automated stuff and might as well do it up right?

I've had nothing but fantastic results with the titan timers, same format as the vivosun, 8 set settings and haven't had an issue at all yet immcurrently running all my lights with them and soon the auto watering system will be on one again as well
I have 6 plugged in right now lol. A couple of them are 2+ years old.
I always leave them plugged in and in the off mode even when not in use to keep backup alive.

Puuuurely bro-science, maybe the switch in light sources from veg to flower could trigger herms in some strains/gene pools? What would plants in the wild do if the distance between the Sun and the Earth was instantly cut in half? Probably burn right up with everything else in the inferno lol

Oh absolutely, it all adds up . And if it's liable to begin with? Trouble lol but I totally agree. Another reason u don't see em outside.

Quit using timers. Even heavy duty ones I found, power would bleed thru to the surge protector lotta times, don’t notice it at first, bout like a big light leak. Jme. Now I’m the timer ? I do the pluggin and unpluggin

Per that pack above, usually a R1 is a reversed s1, which many would think that way increases the herm tendency , but apparently someone wanted more female seeds and didn’t have any to reverse, so they reversed the plant imho

I could be wrong but I was under the impression an s1 is self 1. Ie cut from plant reverse it and put back over mother plant?
R1 is feminised version of f1. R1 is result of two feminised first generation seeds. They then reverse one and it goes over other feminised seed. No cuts or selling? That's how I always read it bit I could be wrong. Can someone enlighten me

This is tangentially related to the conversation here but with my recent run of intersex plants I just want to say this. I've grown a lot of plants at this point. And yes, environmental factors can cause intersex traits to appear. But the reality is the genetics had to be there for the traits to appear as well. It's not one tiny LED in your tent or a pinhole light leak. Even when it's stress induced, the root cause is genetics. And I think the frequency of breeders blaming the end user for intersex issues back when I started growing did a huge disservice to the industry, because it encourage people to continue to breed with unstable genetics by putting the blame on the grower instead of the breeder.

I dont want to stir any pots or anything, just something I was thinking about last night while I chopped yet another plant from an expensive pack from big name breeder. If the primary factor was environment the intersex issues would've been random throughout the tent, not concentrated on one cross.

Lol blame the grower not the breeder starting to sound like tech support. I deal with hermie plants as I've mentioned and had my run in with what I was sure were hermie seeds until the other thread on here where I was talking about this, and the number of Male plants I had showing up, I'm pretty sure it was someone growing around here had a Male and some pollen made it into a few of my plants. That seems more likely than me having 4 or so Male plants from what was bag seed. The numbers mentioned alone.... just so unlikely however possible.

I think timers matter. This came up before.

:D

the timers i use do not impact my lights...and that tiny red light is not going to do shit. If that hermies a plant it is not getting a second chance.

Stable works with a streetlight. Bad Genetics will seek any grower error to be the culprit.

And yes you can get it to happen with stress, but when you see something like that Apple gear that was intersexing with very competant growers...its the genetics.

I don't care how good it is...there are 1000s of crosses...you will find many that are stable.

I guess we just disagree. There is a difference in my mind if the herm tendency if you reverse an already reversed plant vs just reversing a reg plant. Hyb of exe says a plant is a plant as far as reversing, I always understood the R1 to designate reversing a plant that has been reversed. It is odd how many do have probs with herms when others don’t, not sure of the explanation. per the timers, I found mine would let just enough current through to barely illuminate bulbs, you’d have to double check later in dark cycle to catch it

These timers have never let me down and hsve never caused a herm in oh maybe 30 years I been using this style...if your timers let power bleed through they are junk and not the fault of the timer but the fault of whoever used them.

Totally agree with this statement...not going to beat any old horses but there were a few money grubbing hacks that use to blame intersex problems as operator error because they were legends in their own mind and it couldn't possibly be because they had a hand in it.
With so many mixed and muddled poly highbrid's being used these days the intersex problems will pop up more often than not...
It's mostly because things are just done at a very excelerated rate and peeps not taking the time to be sure that it's not likely to happen with solid growing regimes.
Buyer beware!

I wouldn't say disagree, I said the way I knew it a S1 was a self fem. Cut then breeding cut to mum. R1 is a f1 in feminised for reversing a female and putting it across another female plant not the mum. All good mate. As I said at the end, I could be wrong (plenty of times in past I have been) can someone enlighten me. You maybe right, just looking for clarity. All good mate

A few guys wear womens' underwear every day. Some guys, do it once in awhile, when it tickles their fancy.
Not that there's anything wrong with that.
Some guys, one time, with a huge cocaine buzz , wore the strippers thong at a bachelor party. Ok, fine, a couple times.

Plants are the same way. Some will do it always, some will do it almost never.

No you’re correct and I’m not. Sorry for that. R1 is reversal on diff plants, S1 is reversal on same plant. Not sure what I was ? apologies.

waited awhile to reply cause I hate when people think I’m here to bitch or debate. Just giving a 2nd view point on what I think of the hermie views. Just trying to be open minded and everyone has their own views . Not Stepping on anyones feet



The issue is breeders and growers accept the hermie prone plants as keepers and don’t warn ( explain what’s it’s limits & and if it has known always hermie prone issues ) To the next grower to use those genetics that theirs limits or keys to prevent it from hermie stressing , try to grow many hype market cuts at normal ppfd and npk and tell me ur not getting hermies . Sad but if the person who sold that cut knows it’s a trigger vs always hermie plants on the cut there’s a fix . If it always hermies it shouldn’t even be kept as a cut lol ?

point is there is many strains ( more than not on market ) if you are aware and monocropping but also know the issues of the strain these growers will make sure to not promote those issues. Just saying there’s a differance with a plant that hermies for zero stress and will no matter what Vs a ball or two if stress happens ( that’s manageable ) and won’t on a normal environment cycle. Point is if you want a good gem even if cut. You still should hermie/test the pheno if it fits ur needs and works with you. tbh this is why seed pheno hunting is so much easier for a home grower vs others cuts fcause it’s also making it potentially your getting dominate diseases/virus, fakes and also not work for you and your demands in growing/medicine . Just saying anyone can get a good pheno in 25-50 seeds even if it’s multple runs and than keep her and be game. Don’t let people act like it takes acres to get a gems or money. Heck I wouldn’t be surprised if a lot of breeder cuts that are publically given are the non wanted pheno for security of their shit. i was def convinced for years clones and expensive clones = sucess and that’s not true at all.



as experience of pheno’s hunting/sampling for me of cemented “hermie free “ would be as a example my space monkey ( have many just as a example) vs crazy amount I’ve trialed over 7 years ( since having sm) I ran her, not once have I never seen anyone who got her have a hermie from her, and I know she would die before she would. Thing is people say gg4 is a hermie well did my space monkey solve that for me ? I would say yes and also most people didn’t want or care it was gg4 cross cause that sm pheno kicks ass. Not bashing gg4 and I didn’t even have hermie issues from gg4 itself just saying as a grower find ur medium of what pheno isn’t a issue and good meds = your choices Vs trying to force plants that after trialing that want to hermie without stress trigger . Nothing sadder than a space or hermies fucking ur room up, it’s happened so many times and it def made me ocd on subject . Key is once u find ur non hermie prone plant for you and ur room/emviroment and demanded meds. That’s the work and the key ( than ur hermie free ) and also can run her as many times as u want. cannabis doesn’t care if u want to smoke it. It’s goal is to get pregnant and have its next generation of its family and to survive , this is why in cannabis it will self pollinate and in many landraces or certain genetics itself will def be more prone to hermie issues just because they know by time of survival they need to get fuck (pollinated ) or it’s all over for their next generation . people need to realize these plants are not here for you and have been growing in regions where the timing and how to breed is based on that. Just saying ( cannabis isn’t any special to any other thing on that)

just Because a strain doesn’t agree with ur unnatural light cycle, high npk, air pressure, vpd ranges , temps & so many things does not make it a cemented hermie Inless it hermies no matter what ( no stress) thing is also if the strain still is desirable by consumer but hermies on certain enviroment or stresses it has to be corrected by adjusting and that can be done easily by monocropping and documenting the plants desires/unwanted triggers. this is another example of many growers can and will grow strains that they choose just because of vigorous and also they won’t hermie if not even set on fire and horrible enviroment but is that still the keeper or holy grail the consumer and grower wants? so many of the time this is why people exp in this industry Choose bad strains just because the consumer wants it . as a home grower you have to find what fits ur enviroment levels of stress and cycle timing without the issues Of hermies. The balance of what works and ur med desire - perfect fit at least for me

i have heard so many bitching ass people acting like it’s a mystery but when you use genetics that who already hermie so easily and cross it again and again with more hermies = duh

last indoor before current harvest I literally bought 9 breeder cuts for over 1k total and 6/9 hermied. well thing is I gave clones to others but warned what I saw in my room and interesting thing was no one but me saw hermies, but they also were ethier greenhouse or lower ppfd /lower input grows, my guess l. So like many genetics just because it hermies or can’t handle high ppfd/high npk and stresses doesn’t mean it’s not a good smoke. key is as a grower when ur pheno hunting the key is to find strains that work for you and also the smoke works for you/ patients.

thing about all my clones I keep as my keepers, will they hermie ? Not even if I try to reveg midway in flower , heat stress em, high npk and pgr’s through cycle And misc stresses like pest. i can’t support or want strains that can’t be tough but also easy to grow. But I also demand the smoke to be prime too, that’s where u as a grower have to find that medium of what’s worthy cause not to bust anyones balls/ego but 99% of the time time I’ve noticed the nicest looking and also best plant for the farmer, is least valued for consumer and that sucks . But that small % once found and cloned ur set!

this is why when I find that medium of workable, vigorous and hermie free pheno that the consumer wants is my key to keeping her. Sounds hard but keeping every single “gem “ or hype I can see why people get a lil fucked over on that too.


another thing I think Is interesting is ive tried crazy amount of seedlings outdoors and I’ve never once seen a hermie outdoors, I’ve even ran previous round indoor hermies and let em outdoors and whatcha know aka ‘ no hermie. these plants know what’s up
