I can tell your looking for a simple answer. This is how I do it and my success rate is 100% so far.
I used a sterilized razor blade to cut the bottom branches from my best 3 girls. I Cut them at a 45 degree angle near the base, then slit about a half inch down each for better rooting.
I dipped them into rooting hormone and stuck them in 1" rock wool cubes that I cut in half, again for better rooting.
I used this dome on top of a heat mat, and had my Flueros on 24 hours a day. I kept them moist, but not soaked. I also kept it slightly flooded for more humidity. After a week or so, they all rooted and here they are now.
Hope this helps some.
