Agree with Budologist420....sounds like you may have just stuck some cuttings in a pot of dirt? There are some tricks to cloning for sure....and cloning gel helps too? Here's how I clone:
I pick a good healthy stem with at least 2 sets of healthy leaves from the lower half of the plant.
The stem needs to be somewhat fat - scrawny little suckers rarely root
I cut it with clean scissors then stick the cut end in a cup of water
I get a rapid rooter thingy...recut the end of my clone at a 45 degree angle
Dab rooting gel on the fresh cut
Stick it in my rapid rooter - the pinch it shut to give the rooting gel contact with the rr
I keep an eye on the leaves - really only need one set
I keep all of my clones in a tray with about 1/2 inch of water - under a flourescent light - on top of my heater (the heater is off - but the pilot light keeps it warm)
I mist the clones with straight water
As soon as I see roots - I put the whole thing in a coco pot with dirt.
Voila!
