After having some cuttings die without ever producing roots this is how I now clone:
In a small Tupperware of water with a small pump and air-stone for oxygen, a little root gel and in the water they go just above the light or on a window sill. Change the water at least every other day.
I usually will see small roots in three days, I add a small amount of food to the water, after 10 days put to veg or flower. Your right clones just want to live.
regards,
