absplutely you can root clones in dwc, but i wouldnt use small mesh pots. when roots start to grow through bottom of pots, you'll damage roots transferring them to a larger pot when they are ready. instead, get a new lid for dwc, be it a rubbermaid 10 gallon, a 5 gal paint bucket, whatever. now stop at walmart and get a pool noodle. one of those long, maybe 6ft foam pool toys kids use that float. use that to cut circles out of it and cut a slice like the first cut of a pie. dont cut a wedge out like a piece of pie, just one single cut in it like halfway through taking the first piece of pie. now take the foam discs you cut, and use a hole saw to cut a hole in the new dwc lid for each one of the discs you want to use. pnow open the disc kinda like pacman would look with his mouth open and place cuttings in the disc and disc in hole. you'll want water to be around 75F to encourage root growth. you can also buy premade neoprene discs from a hydro store, but theyre about 50 cents each, very expensive. you should see good root growth within 10 days
