I'm growing it dry start right now, and have been doing so for about the past 5 to 6 weeks, along with the lilaeopsis, using a product similar to ADA aquasoil from Mr. Aqua.
I haven't found the growth of the stauro particularly fast, although that might be due to the fact I'm not using a terribly high amount of light on it either. I found it adapts easily. At this point the leaves do have a more elongated shape than those I have in the submersed setup, but it took a while for the plant to look much different from is submersed form.
I use a spray bottle and mist every 2-4 days. I am also using a 50/50 led light that I was using with a previous saltwater setup. so I'm not generating a lot heat either. I keep the tank sealed using cling wrap. The tank is sloped toward the front, so the front of the tank has a very low level of water, when that goes down a bit is when I mist.
The lilaeopsis on the other hand is taking off via runners and is spreading rapidly, but it looked very ragged at first and then recovered. The staurogyne always looked good.
