sorry, my monitor sucks & I cant see well enough but it does look male . dont be in a rush to kill it, it will be several weeks befor a male starts shooting pollen.
none at all....turn off your fans slowly slide a garbage bag over him and carfully remove it from the area it's in and kill it! it is 100% male like mcfonz said
once you are sure its a male, no reason to keep it alive. I was suggesting that unless you are sure its male,it is not a big rush to kill it as it takes several weeks to form enough pollen to cause trouble.
males usually flower faster than females.
I start my males with all my ladies and move them after they look like they have another week or two.
I then move them to my PC grow thats equiped with a carbon filter.
When you grow a male and it gets one flower open its enough to make a few hundred, if not thousands of seeds.
Thats the risk.
If you want to preserve the genetics go ahead and take the risk.
If its a random bagseed or some cheap genetics just trash.
No need to bag it or cut the fans down at this stage - no bananas opened up or close to do so.
