Try cutting at a 45 degree angle about a quarter inch below the 4th or 5th node down from a growth tip. Immediately put your cuttings in water and then head to where you will put them in plugs or soil. When ready, take all the growth off the lower 1 inch of stem down to the 45 degree cut, dip this section in cloning gel or powder and insert it into the plug or soil. Make sure there is good contact between the plug/soil and stem, if you want to scrape off a bit of the outside layer of stem near the cut, there will be more areas for roots to grow from. You can now put them in a humidity dome and make sure it's very moist inside. I leave them without any direct light for the first 24 hours to let them recover from being cut, then they will go under weak fluorescent lights until they grow roots. Make sure you don't give them 24 hour light or they will take longer to root, 18/6 or 20/4 is good.
That's it in a nutshell, I wish you luck, let me know if you need any further help!
