Vanilla cutting's care. Help?

[Ikuna]

Hello!
I received a short Vanilla orchid cutting last week. It had developed 5 small roots when I got it. I planted it into a small pot. The substrate mostly consists of orchid mix (gravel, coal and bark). I also added some low -fertilized cacti mold (peat, sand, etc.).

So far, I have thoroughly watered it once and misted every morning. The cutting gets light from 13W LED lamp, when necessary. I have been trying to provide light for it min. 8 hours per day. The room is about 72-80 F at temperature.

Is there anything else I could do for the little orchid to help it grow? I really want to success with this one and I can invest some money on it's care, too. Can I have a little help here, please? I don't even know if I've treated the orchid in the right way so far.
