New air layer plant need special care?

[bluenkimchi]

I saw some lychee newly air layered(un-potted) on Ebay for a good price and I might buy some, but is there any special care requirements. I've looked online and saw some youtube video but all they show was planting them in a 2 gallon container and keep it in a shady area for about 1-2 months then transplant to something bigger. Is it really that simple or am I missing something? Please advise as I don't want to waste money on something that I can't keep alive.
