YOU ALL NEED TO LEARN THE OLD SCHOOL WAY!
I take my cuttings from low on the plant. The higher you take them from, the more N they'll have. The more N they have, the longer they take to root.
Take a cup or what ever you'll use as a container to hold the cuttings. Pour in enough "Willow water" to have 2" of stem in the water.
Now simply place the cuttings in the water and set it away from direct light.
You want them to get indirect light only....not even a small cfl over them. Mine sit like 10 feet from the nearest light source in the veg room.
Because the cuttings are not in direct light, they are not trying to "grow", other then to maintain life and grow some roots.
The lower leaves will not yellow or age. It takes about 10 days and you place the rooted cutting into your soil - or what ever, and they take off like mad!
No dome's, no media's - just willow water and patience.
I never bothered to adjust the pH either. My waters about 7.0
