I think a lot of factors play into certain genetics stressing out at lower stress levels than others. This could cause plants to herm while others in the same grow will do fine. Some growers take this as it's the genetics which can be true considering the sensitivity to environmental factors. Nutrients fed to the same plants from the same pack of seeds can have different effects considering various pheno expressions & their sensitivity to the nutrients. This can cause herms as well.
These things should be taken into consideration by the grower & balance out the plants needs before screaming herm & bad mouthing breeder(s). This is the process called "dialing in" the plant & it's environment.
I believe cuts from a seed plant should be flowered alone in a tent away from keepers or cuts that are tested & stable. Don't wanna mess up a crop right?
We take risks & chances when buying anyone's genetics as well as growing them out in a "dialed" environment. Dialed be the key word here, lol! I know it takes a lot to admit that we could of done something wrong but unless we are 100% sure, we should do at least a few solitary runs on any plant(s) we grow from seed & their cuts. If you grow from seed, take cuts & flower them out & see what needs to be done before putting up statements of genetics having herm problems.
If ya don't wanna do all this, then try finding tested & stable cuts if available & that would solve half the problem. I say part bcuz some cuts can herm from non-dialed rooms. Then again you must find that plants needs (dialing) too. Unless you get the low-down from the grower you got the cut from.
I take as many precautions as I can to prevent stressing the plant. I only have 2 spots to flower which holds a few plants in each so I have to be on my toes. Feeding organically helps a lot in herm prevention too.
BUT there can be problems with genetics too & this can cause a lot of wasted time, money, & stress to anyone. That's why research is key to a good grow IMO. Watch for people's grows with dialed rooms, what is fed, ppm's, lighting, CO2 use, sealed or unsealed, medium, etc. Bad reviews from great growers will also let you know what's good or not or what to watch out for. Testers are also serve as a great tool so watching their grows also helps.
I'm a small grower & have no access to cuts so growing from seed is a gamble & I know this from jump. I also research then make decisions.
THIS IS ALL MY OPINION FROM WHAT IVE RESEARCHED so dont take it as you please.
Remember it's a weed & you can't have full control on the outcome. It's a process & we all look for stellar results, right?
(Please give your opinions after reading this. I like to learn from others as well, thanks.)
