Do
Do seed sacks have white hairs growing from them or not...
Sigh....I don't reply pay attention to such mundane things....once it's seeded, it's seeded, there's nothing you can do or change it back to something. But to answer your question as much as I can remember when my plants got seeded.
Yes, the calyxes swells up...fattest bud ever....and like you, I hoped I'm getting some really nice fat buds.
Once a calyx is poliinated, the pistil start to dry up. So No, pollinated calyx don't have white pistil.......But wait, before that statement makes you hopeful for fat calyx....2 things
1. In a cluster of seeded calyxes there would still a bunch of white pistil developing between those fat calyx.....plant doesn't stop producing white pistils until the plant is finished reproducing. So in essence its easy to mistook that a seeded calyx has white pistils. The only way to be sure is for you to break down the cluster (nug) and see for yourself if that fat calyx has white pistil.
2. It would take a couple of days for the white pistil to totally dry out. So, if a calyx is pollinated and starts to swell up, it may still have the white pistil. And again the only way to be sure is to observe that calyx for a couple of days and see if it losses its white pistil.
In reality, its bullshit...who has time for such crap....you better off accepting the fact that your crop got seeded and move on....and start planning whether you want those seeds for your next production.
