You can clone w/o hormone if you need to, but if you can definetley get some, it quickens the process. The most basic method to clone is simple water cloning, all you do is take a cutting, tweak it so the stem has no air bubbles on the bottom underwater in like a cup of water and put it in indirect lighting(leaving your clone to be in the water with no leaves touching the water, you might have to use saran wrap over the top and poke a hole in the wrap for the stem to hold it in place for smaller cuttings), within 2-4 weeks the cutting should root for you. You just have to watch and wait.
