Hi Chips,
You'll get different answers, becos' everyone has their own way of taking care of their new arrivals.
I like to give them a few days to get adjusted to the new area - I
do not put them with any other plants or orchids. I set aside time to get a good look at the leaves and roots. I quickly check them for any insects/ pests and water if needed. They go under dimmer lights then my other greens for a couple of days.
I always repot no matter what. I'm a firm believer to get them in the media that you grow best in.
Don't rush anything, give it all some time to get adjusted.
I've got an order comming from clouds tomorrow, I'm pumped
Congrats on you're new kiddo's
