What causes herms?

[Z71banshee]

So, last night I was moving things around a checking over plants in the flower tent. I have a Mo Swayze 21 days in that I found quite a few sacks on. She was late to sprout and had been root bound, so I blamed it on myself. Then I started to look closer at other plants and I have two Citrus Gorillas (both clones of the same mom) at day 59 that I saw nanners on, and then a Gorilla Skittlez clone and a Cherry Pie Fem seed, both 21 days in flower and both have a few sacks down low. Is my luck that bad that I could end up with 4 strains at once that hermied?!……or can something in the environment trigger them?
Environment is a 4x4 tent with close to 600w of LED. Lights on, temp and humidity are around 74-76 and 50-55%h. Lights off the temp is around 64 and humidity jumps to around 62-65%. Lights are set at 11 hours 45 minutes on. Everyone looks super happy and thriving in the tent, just baffled that 4 strains hermied at once.

So my eyes aren't that great anymore, but are you sure you see sacks on the one pictured?

 

[Hitch]

To answer the question, quite a few things can trigger it, light leaks being primary.

I've had a plant show some lower nanners before that I'm 99% sure were caused by a little LED on a timer that was way brighter than I realized.

Aside from this, humidity is high for lights out, but I haven't heard of high humidity causing herms, just PM and mold issues at that temp.

Like @Hitch said it's a variety of factors. Stress and genetics are usually the two biggest factors in my experience. It just so hard to pinpoint the cause. I had a run a few months ago where half the strains I was running showed intersex traits. Nothing in my environment was different from past successful runs so I assumed it was just bad luck. In general, there seems to be more intersex traits in modern genetics than I recall seeing historically.

Ya it's wild now, very common , and not many are testing either which it should be the opposite smh .

It's crazy how many strains are released untested these days, especially when you consider the price tags on some of them. It's even crazier to me how some breeders can have so many intersex issues and still have a rabid following that just brushes it off. I'm a little frustrated with few bigger name breeders at the moment

Plus it's a mad dash to get those runts crosses out and all the collabs. Some of these breeders are dropping new s*** every month. It's also killing my wallet

This doesn't look like a hermie to me. It just looks like weird female flowers that should grow normally. Just keep an eye on them for now.

The picture is piss poor, but it’s the only one I took. I questioned it for a few days because of the hair coming out, but it was in fact a sack of bananas. Here’s a picture of the nanner on one of the Citrus Gorilla plants

@Gentlemancorpse that eases me a little to know that others have had multiple strains intersex at once. I was a little discouraged, but I did a lot of “house cleaning” last night! Cuts and lower quality strains hit the compost pile!

This is one thing I’ve been trying to work on. From everything I read, I need those humidity numbers to be flipped. I just haven’t had good luck with automatic humidifiers/dehumidifiers. They either run consistently or won’t turn on automatically. Right now I’m just playing it as, “don’t fix it if it’s not broke”. I haven’t seen any pm issues and everyone seems to be happy in the tent.

Bummer man, I was holding out hope. Sucks to hear and hopefully you still get a nice haul of buds.

While it is a bummer, it forced me to thin the heard, which was needed. The citrus gorilla was ready for the chop, so I took them and there are three other good sized plants that are within a week. The only issue I noticed with them three…….a few beans are showing. I picked off the sacks and left the Cherry Pie and Gorilla Skittlez in because they are smaller plants, so I can watch them close.

Usually stress of some sort, as mentioned light pollution is a biggie although there are others. Funny that topping and LST never seems to produce herms.

I had one on an auto several months ago with no stress other than her being deformed genetically but the frosty smoke she gave me is worth growing out her seeds for I hope more killer smoke.

Ouch, yeah once you spot those anthers, you’re probably already seeded. Unless it’s a dud, but I’m never that lucky. Damn that sucks. Pretty plant though fwiw. I sure hope it’s genetics. Maybe try a run with something you know personally to be stable for you? Suss out whether you have stressors in this particular tent?

If you already have the humidifier and dehumidifier, then a humidistat will fix the cycling issues. But I admit that I’d probably do what you said and fix it when it's an issue.

Looking at the genetics that it has happened to, it isn't super surprising, gorilla glue was the result of a unintended hermi pollenation. Cherry pie also has a rep for being unstable. The simple act of growing inside is stressful, it makes the triggeŕs for intersex just that much more sensitive from what I have seen.

 

[Z71banshee]

@Hitch i have a couple wedding cakes and a couple Sun N Juice clones that will be ready to go in a few days. I’ve had both of those run quite a few times and know they are very stable.
And now that you posted the picture of the humidity controller…..I just remembered that my dumbass has that exact controller ??‍♂️

In a different thread someone hypothesized that inducing flowering on immature plants may also be a trigger for intersex issues.

It's hard to tell in your first picture. I'm always looking at those bracts like they're possibly sus. Sometimes they start looking a little too much like male flowers, so I know exactly what you're feeling there.

Who ever it was, I agree. Early flower inducement is a huge hormonal shock. The longer flowering the strain the more it seems to affect them.

What would the explanation be if you ran a ten pack of the same strain, got 8 shirleys, and one hermed?

Is it safe to say that most every strain will throw a herm plant if you run enough of them>?
