Why are my plants becoming hermaphrodites? (Critic...

First, ensure something you don't realize is occurring is not the cause -- specifically light pollution - from ducts or opening tent during dark cycle of flower phase or anything like that... Yes, a minute of light pollution is a problem, lol. It's completely avoidable so don't do it, if you are. No reason to 'peek' during dark cycle of flower phase, ever. The idea behind UV is that it damages the plant and its response is a net positive while considering that damage. Even though you can probably find some research that supports it, it's still more of a hypothesis than a documented / known relationship with a predictable effect. So, yes, it could be the UV as it definitely damages the plant. Stress can cause herms. However, not all plants are robust. Some hermie more easily than others. If it is happening consistently with multiple strains and seeds, I would look at adjusting how much you use UV per day, but if it's rare i'd chalk it up to the genetics. I'd rather criticize my own efforts first to be certain... than automatically blame and outside source of the problem. Time will tell. UV won't do much for you until trichome production ramps up, so if you are applying it from day 1, i'd adjust that, regardless of whether it is 'a' cause of the hermie issue (again, this is a hypothesis and no gaurantee it helps you plant in the first place, so keep that in your mind too). if you continue to get herms regardless of variety of genetics, you might be applying too much per day etc etc... apply some deductive reasoning, start changing 1 thing at a time, and when the problems ceases, you'll have a better idea of what was causing it. Plants outside develop resistance to UV. This is why 'field' tests involving uv and marijuana didn't show any correlation. The 'maybe' of UV is only with indoor research. as you try to be systematic to figure it out, remember the sample sizes you deal with are part of the problem too... it's easy to be fooled by a false positive or negative when dealing with only a handful of plants. Keep an open mind about cause/effect and it may take several more plants to be certain.

UV exists outside all the time. I doubt it would be causing Hemi's but maybe when its just turned on and off like that... IDK. not sold on that idea. Also don't need it indoors. its just a hazard. To me it screams genetics. or maybe their is a light leak? Could also be something weird in the feed, but not likely. Pluck the balls off as best you can. and see if it keeps growing more. I'd try and finish it. or just move it outside and see what it does.

Hey 👋 Hab mal durch deine Reports geschaut & gesehen, dass du diverse breeder verwendet hast… die Wahrscheinlichkeit, dass es also an den Samen selber liegt, ist demnach geringer… aber nicht auszuschließen. Ansonsten bleibt nur jede Form von Stress, die die Pflanzen dazu treibt… ist aber fast unmöglich die Ursache hierfür klar zu definieren. Viel Erfolg beim nächsten grow 👊🖖🍀

try using Mephisto, or Night Owl Seeds for some serious genetics

genetics, genetics, genetics

Are they herms? Or are they intersex sites? Huge difference that quite literally means everything. bad genetics = trying to pollinate itself on schedule for viable seeds strong genetics = often caught with last minute attempts to pollinate, much after her own window using Barneys means you likely shouldnt have to go further than that...they're old, whitelabeled, mystery beans (likely very old)

I was of the belief that UV light is only beneficial during flowering. Using it during veg may be the issue?? Try next grow without UV during veg and see the results for yourself maybe?

If you’re using the same seeds as “last round” I’d say it’s a bad batch of seeds. Toss them and start with a different batch.
