how do YOU think these got pollenated?

After chopping down most the original plants, I started up nutes again and gave the side-buds 4 more weeks. There weren't any seeds in the first batch of buds (4.3oz dry from 2 plants) but for some reason this extra batch ones have seeds in them. I checked the whole cab and all the bud-sites and there aren't any pollen sacs that came up late and believe me, there's not a forest of males outside the growroom. What do you think triggered them to do this?

My guesses:
*last ditch effort to *somehow* pollenate themselves
*It is springtime and all kinds of plants are blooming, so they got tricked into thinking they were pollenated, giving me sterile seeds

I'm not really mad because this is just extra, but I'm wondering if someone knows what happened..

thanks

bump.. for pro opinion

I have seen a plant that only had a couple seeds in one bud. Upon further investigation, There was one male part in the middle of two compressed buds. The pollen could not get air born because of it being so deep in the bud. And it only takes on male sac to pollinate quite a few buds.

yeah thats my guess, it was a pollen sack that is somewhere inside the bud.

Or it went hermie. I just saw a plant that flowered beautifully but ended up with about 10 tiny, yet mature looking seeds.
