Here is photo with my phone up close as possible.
I appreciate everyone’s response 
I’m hopeful these are friendly.
I’ve not changed anything in the tent in at least 5 months. All the same everything. I’ve also been home for 18 days on holidays, so it can’t be from outside via me. 
but these are actually bigger then the usual micro bugs and micro worms I see all the time. These are slow moving and don’t jump… took them a few hours to move from the other side of the party cup kinda slow.
Sounds like me lol I’m not familiar with all these types of bugs yet. So it’s automatically dangerous 
Maybe a springtail? They are used for feeding frogs…
I would just take an eye to the seedling evolution, it will tell you if they are friends or foes, 
time will come then to take the right decisions, but that’s another story … 
They don’t jump or move fast. So probably not… I’ve seen spring tails before.
I’ve been watching videos and photos and reading about common and uncommon pests and beneficial bugs…
This video looks identical to what I’m seeing
Dust mites?
Otherwise hypoaspis miles looks very close, but the videos show them moving quick. The ones I’m seeing are moving real slow like in this video.
This is my video I took with the microscope
Its done uploading now, please watch it.
Those are most likely decomposer mites - maybe orabatid mites. There’s too many of them clumped together for H. Miles (now called stratiolaelaps scimitus). With that said, there are too many of them which makes me think you have something going on in your soil. Maybe a little wet, too many un-composted amendments, etc.
Some sort of bulbous soil mite, they eat decomposing matter. Just means ypu have a living soil. 
Thanks guys you all are awesome… freaked me out seeing that many all at once.
Yes this one cup is actually unintentionally really wet. Gotta dry out.
Yea I seen something about this mite too. Looked alot like them. Says they eat bulbs of plants or something 
I would get these in my small worm bin when I added too much organic matter with perhaps a little too much moisture. I could not remember orabatid, the name. I would have a bloom in Hypoaspis population it seemed, as the orabatid dropped in numbers.
Ya nailed it. Party cup with too much organic matter/dry nutrients and too wet. Not intentionally, but it happend.
You guys are all awesome
Excellent video!!!
If you like bugs 
, couldn’t watch the whole first video he posted 
, I don’t want to finish buried and eaten by that troupe … 
Then you would not like Ants Canada on youtube…
Ants keeping challenge? 
Not for me! 
Love to burn them with a loupe when I was a kid …
Dad?
Yeah, I was taught that at a young age too
