I started these from seed in early spring. Then made cuttings in June. Wondering when I need to repot them and get them acclimated to the great outdoors.

Move them out now, acclimate them to full sun over the next 2 to 3 weeks, then plan on repotting them next spring.

They’re fine being in those little seedling trays for that long?

You can repot small seedlings or cuttings any time of year, even bare root should not worry them.
Another strategy with these individual plugs is to leave them in the trays until you feel the roots are being constricted or drying out too much then just lift the whole root ball out and gently place in a larger pot and fill with extra soil. That should keep them going until repot time next spring.
Definitely get them outside into sun. If they have not had bright light I'd transition to full sun over a 2 week period or you may get some sunburn. You will probably see a check in growth as they adjust to the changed conditions but then get going again when they have acclimated. Also watch water after changing to outdoors. It is likely they will use more and more is likely to evaporate too so may need to water more often.

Such conflicting advice. They’re in sand, vermiculite , and perlite right now. My only concern is them drying out quickly.

That doesn't sound like conflicting advice to me. If you're concerned about them drying out...
I think you got all the advice you need. Then again, I'm just some random dude on the Internet, so who knows?

You seem like a bright guy. I’ll take your advice

Years ago, I annually made JBP seedling cuttings in June... metro Atlanta. Once rooted and back out in full sun, they were watered with my other trees... usually once a day... and did just fine until the following spring re-pot season, usually March. Honestly, I'd be more concerned about rabbits or chipmunks eating them then them drying out if you water regularly. Anyway, you could always re-pot one or two and see what kind of root growth you have... up to you. My seedlings went into an akadama based soil...

Haha, then you need to talk to my wife. She may disagree with you.

Great idea. I’m gonna use akadama based soil as well. We have squirrels and birds bad here in south Ga. my cats ain’t worth a crap at defending either. Smh. So if I have decent roots go ahead and repot them?

I've read that if you use Irish Spring soap in your garden....squirrels hate the smell. I want to try it but don't have anything like netting to put the soap in. They eat our orchids.

Up to you, really... I haven't had great luck messing with the roots of any tree this late in the season.

Looks like you have a few... you could try both repotting and waiting.
