4 week ago I trimmed a branch of my actinidia kolomikta and decided to try my hand at rooting some cuttings. Some were in plastic ziplock bags, some under a big glass jar, a couple in a cup of water, and some in a plastic bottle cut in half and taped back together. I would open them and spray with water once or twice a day and they also had some bottom heat for the first two weeks.
The results are in! Some of the cuttings rotted - they were way too thin and the medium was probably too wet. Some are doing fine and started sprouting new growth lately.
Here's my questions: when is it ok to open them up and expose them to drier air? Do I need to do that gradually? Any tricks to it? When to repot? After babying them for 4 weeks I'd hate to kill them now!
My second question is a bit unusual: today I noticed a root on one of my cuttings that's sprouting right next to the new leaf. That's good 2-3 inches above the soil! I guess I overdid it with spraying?
Here's what it looks like:

What do I do with it now? The second cutting in the same pot is not as advanced and I am a little hesitant to disturb the roots and try to replant this weird one. Should I just let it be and see what happens? Should I assume it has roots under the soil level too? Here's the setup for it:


What do you think? I would appreciate any input. Thanks!

As for when to expose them to dry air do it gradually. you will have to use something different than the jar to do that. Maybe a clear plastic bag tied tightly then each day or 2 open it a bit to get it acclimated to dryer air. Good luck!
