Project 1: Hindu Kush

Well I finally got clones, 4 hindu kush babies that are in good health. However one broke in my backpack on the way home (no car up here in SF so I took public transportation). One is already a small bush it seems and the other two are looking good. The big one is 10 inches already and has a lot of leaves. They are all dark green leaves on all the plants.

Any one have any recommendations or advice on growing hindu kush? Thanks in advance!
