Hi
Could someone please explain (in detail) the difference between nanners and a plant that has turned hermie?
Thanks!

'Nanners that happen around the middle of flowering are from hermie genes but those that may happen when the female plant is kept growing after the time she is ripe enough to be harvested will produce female seeds if their pollen is used to pollinate itself or other females.
A full blown hermie plant will grow normal looking male flowers (balls), sometimes just one here and there, at the same time pistils begin growing at the onset of flowering.
Bananas are rarely round and they don’t look like a normal pollen sac. Instead they’re often elongated and yellow, giving them the nickname “banana”. They also often grow together in bunches that can look like a bunch of bananas.
These can be a lot more difficult to control than actual pollen sacs, since they start pollinating everything in the area as soon as they appear. If you have a big banana problem, it may be best to harvest the plants immediately and cut your losses.
What are they? Bananas are actually the exposed “male” parts of a pollen sac, called the “stamen” which would normally be surrounded by a sac to hold all the pollen until it bursts open. If you open up a fully formed male pollen sac, you will see bananas (stamens) inside.
But when bananas appear on your plants, they don’t need to “burst” in order to spread pollen, they will immediately start making pollen and often will seed the buds that are close by even if bananas are removed right away, and sometimes the pollen can drift to other plants and pollinate them as well, too.
The yellow bunches in this bud are bananas/stamens and will pollinate everything they can - they don't have to wait for a pollen sac to burst
Bananas ("nanners") in your bud means that you have a hermie plant, and a hermaphrodite plant is capable of pollinating itself or other buds in the grow area
If a female plant is allowed to go too long without being harvested or pollinated (allowed to go past the point of optimal harvest), she will sometime produce a bunch of bananas in her buds as a last-ditch attempt to self-pollinate and create seeds for the next year. This is sometimes known as rhodelization. This is not as destructive as other types of hermies since it only happens after plants are already past the point of optimal harvest.
What causes it? While genetics does play a role in whether a plant is capable of producing bananas and mixed gender buds, environmental stress is often a big component in causing bananas to form. Luckily if you stick with high-quality genetics, you are much less likely to run into bananas even if you do accidentally stress your plants.
What type of stress can trigger bananas to form on cannabis buds?
Inconsistent Light Schedules & Light Leaks - When plants don't get light at the same time each day, or if they're exposed to light during their dark period (light leak)
Heat - When temps get too high hermies and nanner often appear.
Too-Bright Light - Like too much heat, light that is too bright can stress your plants and trigger hermies. This is most often caused by growers keeping their lights to close to their plants. You can light-burn your plants even when temperature is under control.
Major Plant Problems - Major plant problems like nutrient deficiencies, root rot, pH problems, light-burn and nutrient burn can all trigger bananas to start growing
Genetics - While stress plays a big role in the formation of bananas, the tendency to form them seems to be genetic. This tendency is very common in the seeds of a plant that hermied - these “feminized” seeds, while always female, are much more likely to show the same herming traits as its parent.Growing seeds that were produced this way is naturally selecting to produce more buds that grow unwanted bits

coulnt have said it better my self thanks Bapple

I'm no expert but here's my take;
1) hermaphrodites will show pistils & sacs under any conditions, high stress or no stress. Self-pollinated seeds will produce hermaphrodite genetics.
2) female seeds with no hermaphrodite genes can sometimes produce nanner's under high stress conditions. Self-pollinated seeds will produce female seeds because they're mother was not genetically hermaphrodite but produced seeds out of stress. Some female genetics are stronger & more stable than others thus less likely to go 'banana's' lol!
All female plants will eventually self-pollinate if left to grow past they're prime as a survival mechanism...& I assume sometimes even earlier if certain conditions are met.
At the moment im growing an iced widow & c99 with seeds that came from nanner's. One of the c99's in my last grow self-pollinated & pollinated one other iced widow. So hopefully in a couple of months we will have a better understanding of whats what.

Thanks guys. That all makes good sense.
