DWC= Deep Water Culture. DWC setups are very efficient, I have done much experimenting with this type of set up. What I found I liked was I took some of those tubes of lays chips (kinda like the pringles tube, but plastic), cheap aquarium air pump, some air line, air line splitters (dont split the line so many times that you burn up your pump) and hydroton. With these ingredients put together in the proper fashion, I had a 90%+ success rate making clones. No nutes, no hormones, just tap water.
I highly reccomend using DWC for cloning. I've never done a plant all the way through in a DWC set up however, but I've seen countless posts of beautiful plants grown in this manner.
