I can't see any pollen sacs, so can't say that it's a herma, but it's definitely been pollinated..
If you see pollen sacs, spray it with water, and then put a bag gently over it, before you cut it down, to avoid spreading the pollen everywhere..
- It's a pain to clean if inside, as to not risk pollinating the next batch, and it's a dick move to let it spread outside, as it might fuck with the grow of someone else.
