I can't really see shit, but in the second image it looks like it could be springtails? I have some in my 5x5, don't mind them. No mold or issues with them in there, they all the old dead plant matter and shit.
Good to hear! haha. Man I was bugging too. I ended up having hypoasis miles in my soil too, naturally occurring! I thought for sure I was fucked when I saw them all, but they're just cleaning up the soil. I think there is a chance the springtails will much on roots, but pretty much anyone I've seen talk about them left them in their soil and they've been nothing but beneficial. They eat mold and things that cause mold. lol. Can't beat that. They're probably just munching on old dead roots.
