This is my first attempt at them. I just built them a ring from black airline tubing to keep them contained so they do not flow all over the top of my tank and get stuck in the overflow. I use airline suction cups to keep the ring bound to the tank, and release it when I turn the pump off and the water level lowers. I've only had them since Saturday, which they had baby roots at that time, so these roots have grown a lot. I have not added any nutrients to the tank (I will be in the future, when I add more plants, or if these start to die) and they have taken off like crazy, so I do not think they are overly hard to handle. Like I said though, this is my first attempt, someone more experienced in these should be the one you go to for actual helpful information.
