Experiment: Cloning Tomatoes

So I accidentally broke the main stem on one of my big boy tomato plants and tried to save it however it was to broken so instead I cut it off hopefully saving the plant, and placed the remaining part of the stem on a cup of water which I will keep in there for a few days changing the water everyday.  Hopefully if all goes as planned the stem ill begin to root and I can place it right next to its ol' friend in the new tomato box and successfully clone a big boy plant!  I also am doing the same with a big sucker off my other cherry plant I will get pics up asap and keep everyone posted on hows it goes!
