I’ll dip my toe in the shark tank.
Background: I’d consider myself a beginner who’s being growing on and off for 44 years, all out doors bar one successful hydro closet grow.
In my humble opinion,
All females have the potential to herm. I’d imagine it’s in the genes, as not all plants do. When I got serious about 30 years ago, I started chucking some pollen very early in the flowering development for both seed and to convince my girls there’s boys about so they keep producing female flowers. Seemed to work? Never got a herm and found a few unicorns in my haphazard breeding program. I assume at some point the herm switch happens as the girls want to be knocked up (that’s genes not environmental) though it also makes sense environmental stresses will trigger.
To this day I’d guesstimate 60-70% of my females have seed from pollen chucking, some individuals can have up to 5+ males across them. Still 90+% seedless.I think it’s a little OCD on my behalf but I enjoy the process. Lower branches are fertilised and tagged. Choosing a male is a random affair of stem rubs, plant structure and colour so pretty subjective but mostly because it’s the only male available. I select females for several factors, mold resistance, potency and structure for - ease of manicure and prevention of 1st point. Only thing that strikes me is grandfather is important.
The last 6 years of cultivation in my current location, the only single herm I grew (there was a 2nd see below) was from some seed created by x’ing my male over a neighbours female, and then I only noticed the bananas after the cure and during smoking.
I’m pretty good at neglecting plants, stressing them and fucking up, and still no herms. The only thing I’ve noticed from this, is I trigger earlier flowering. I don’t even actively search for bananas.
So in my delusion I’m quite happy to believe my pollen chucking and knowledge of my seeds genetics is preventing herms

. I’m a bit more wary on bought seed for their 1st grow.
MSNL still get through but currently at 33% success rate for me last 12 months compared to 100% from other companies. I’ve liked their seed and never had a herm but have moved on to new suppliers to supplement own stock. As I’ve started some Thai this year, I’ll be more wary.
If I give away seed, I call it random shit. I never say it’s this or that cause I have no control of the results. Fuck being a commercial seed producer.
Anyway that’s my pointless ramble, play the ball kids not the man.
Pic of something I’d never seen, male herming to female (from same batch of seed mentioned above)

Anyway I’ll keep scanning old threads, but am keen to start a pollen one.
Advanced upfront apologies for rambling, being off point and unintended offence served up
