Will excess darkness hurt male flowers?

So this is an out-of-the ordinary photoperiod question:

I’ve got a male that I want to keep for pollen but I don’t want him fully pollinating all the bud sites of a female side project that I’ve got in a tent. I’d rather pollinate one or two colas selectively with collected pollen.

So while I’m flowering her, I was planning to keep him under an LED outside the tent and just cover him in a reinforced box to ensure total darkness.

However, this would involve getting him covered and uncovered by that box at the same times every day — probably for a couple months or more.

What if I oversleep one or more days and forget to uncover him? I’d imagine that’s much more likely than forgetting to cover him at night — though I suppose that may happen as well, especially if I’m out of town and need to have my wife remember.

In any case: Would exposing him to excessive periods of darkness a few times create any issues with the male flowers? Do male flowers ever hermie by sending out female pistils?

And even if he does hermie in this fashion for whatever reason, would that create the same kind of problems in his progeny? In other words, I don’t particularly care if he would self-pollinate some hermie female flowers. But would I have to worry about his pollen then containing some undesirable traits?

Once male plants have formed structured pollen sacks, it pretty much doesn't really rely on light anymore to dictate what happens. Light irregularities don't matter nearly as much for males when they are nearing the point of dropping pollen.

In my early years, I would just snip the branches off the male plant and put them in a vase on my kitchen table, with a piece of bristol board underneath the pot until pollen started falling.

I now use a closet with a 43W CFL on a 12/12 timer, but only because I have the space and the equipment already available, and I'm often doing far more than just a single male plant at a time.

The pollen is air born, you have to take extreme precautions when having a male plant.
I’ve grown males before and haven’t found it to be as big a deal as I expected. I applied the pollen to certain colas outdoors and didn’t take extra precautions about the other ones, but the amount of seed in the remainder of the flower was low.

I’m not all that fancy, though, so what’s acceptable for me would probably shock someone who won’t tolerate anything but top-shelf sinsemilla.

Be very careful of that pollen spreading. Years ago I had a male plant that I was growing in my veg area which was very close to my flower area. I tried my best to take it out of a veg room, and into a dark closet 12/12. It was far from perfect of a 12/12 schedule but still easily stayed very healthy and produced a LOT of pollen. If you mess up here and there, don't worry about it, it will still grow fine. The problem is I only wanted to pollinate a single plant. The pollen spread to my entire grow and I had seeds everywhere. Even a different room that was further away. I suggest if growing a male, keep it far, far away from your females. It is no joke how much that shit travels.

I have never seen male plants produce female pistils. Only Female Plants throw out pollen sacks which can happen from both stress and genetics. I have also seen it happen in both feminized and regular seeds.

Lol right. And even if it did. Is that a problem? And would that be a "masculinized" seed that only produces male plants? What a nightmare that would be! Would be a good joke to play on someone... send them a 100 piece tester pack..... 100 males BAAHAHAHAHH.

Growing males is a good way to keep neighborhoods clean of locally grown seedless marijuana.
