There’s just soft material in the sacs. Nothing hard like a seed. WTF is calyx from foxtail ?? . I am reading about it now. Another aspect to growing I didn’t know about. I was a little freaked out when I saw these balls. I don’t have a lot of room in the grow room, so I moved the plant as far away as I could, Maybe a foot or so.
If they’re seeds it either hermed or everything else in there has already been pollinated too.
Foxtail is essentially buds creating other buds. Usually from stress, so it’s potential that’s what you have. Just as easily stress caused them to herm.
