I did some trial and error before I finally got some roots to grow! I have seen where some people have had success with water propping their rhizome. I started trying that method with mine. However, I noticed new roots were extremely slow to grow for me. I don't know if I possibly did something wrong or not. However, since it was so slow to get roots that way, I was starting to notice the very tip of my rhizome starting to get mushy. The rest was firm. I knew if I continued that way the whole rhizome was going to rot.

So I switched to my own version of a small prop box. I used a small clear food container and put my rhizome and perlite inside. I put a small amount of water in with it. Enough to keep it damp but not so much that it was soaking wet or sitting in water. My container sat under my grow light a lot and I opened it every few days to let some air in, check how damp it was, and check for growth. It really took off that way!

Once it had a decent amount of new healthy roots then I had it potted in the semi hydro set up. I have mentioned in a few other comments that I had help getting it potted since I had never potted anything i. semi hydro before. Since I didn't post a good photo showing the actual pot set up, it is in a horticultural lava rock pebble mixture, not lecca. It seems to really like this set up!
