Forget the rooting hormone, it's snake oil in my honest opinion. You can just put it in some non fertilized soil and keep it moist and it will root. The best way to go would be to make a bubble cloner and root it in there or get some rockwool cubes and make a humidity tent. The clones want high humidity and VERY little nutrition. Keep them looking as happy as you can and wait until the leaves start to yellow a little to remove the tent.

Get as much light and air going as you can.
