Stress causes male pollen sacks, which will open up, release pollen and and pollinate your flowers, which will then slow flower production to a near halt, and focus on filling your calyx's with seeds, seeds are ripe when they have turned the proper color and busted out of the containing calyx. I am hardly the expert on it.
If you want seeds of your current plant you would have to make a clone and reveg it, find a male of the same strain (or a different one if you are looking to make a cross) and then breed the two male and female flowering plants together. I do not recommend using a revegged plant for breeding, strains lose vigor and yield when they are revegged.
What you can do right now to get seeds off your plants is carefully collect pollen off a father in another grow room, change your clothes and take a shower, then bring this collected pollen (in a container of some sort you used to collect it) and gently brush pollen onto one single flowering branch with a small paint brush. Turn off all ventilation equipment in the room for this process. Go ahead and cover this branch with a paper bag before turning your ventilation equipment and fans back on, remove the bag once seed production has started, and be careful not to shake the plant.
Of course, you can also stress the mother-loving shit out of your current plants, until they hermie, and pollinate themselves, but I DO NOT RECOMMEND THIS. Your plants may not hermy and you may just dramatically cut your yield due to stress. A plant that made hermie seeds are likely to create new plants with hermaphrodite tendencies, and that is no good.
