Depends on what the goal is with the clone.
If it is just to tell sex then a cup of water and 12/12 under a flo or two will work.
If you want to root it. Then you can keep it in a cup of water under 24 hrs. of light.
If you want to root it in soil. You will need to purchase some rooting hormone powder found at most greenhouses. Look for Shultz take root or Rootone. Just follow the directions and make a humidity dome.
