I was planning to catch the show live, but I will be on that road during that time.
I love emersed grown plants. My emersed box is as much fun as my full on aquariums. However, I do agree with Somewhatshocked that they look great submerged. They would be great in a shrimp tank, or any tank for that matter. I think they are a very viable aquascaping tool.
Your setup is looking great Kiran, and good luck with the show today. I will be sure to download the Podcast next week.
