growing for seeds only

I have some kali mist seeds that I want to grow for more seeds. I don't want to take up a lot of time in my grow room, so can I start them smaller and how many seeds would I get if I started at 12 inches with 1 male and 1 female. I only want around 40-50 just to have for my growing needs. plus are there any things I should know about growing for seeds or just do it like normal. Thanks for the input !

i pollinated one small lower whispy branch on a girl that finished just shy of 2 ounces dry weight and got 23 beans
don't waste a whole plant for fifty beans

I don't understand why would you be 'wasting' a plant? The pot I smoked way back in the day always had seeds and stems you simply groomed it and smoked more of it because it wasn't as potent. But it's not a waste and it does the job nicely and you'll have seeds.

So if you want you can pollinate the entire plant or just a few branches, go ahead!
