ok so the hc did not fare very well because my light wasn't putting off the right spectrum. I've added some 2700k and 4500k white LEDs to counter balance the 10000k whites i've had on it and so far it's doing better.
I removed all the HC, and got some Mini Pelia and fissidens in and glued onto the rocks. I'm going to get some more HC this weekend and do another dry start.
the plan is to have HC all along the bottom and the mosses on the mountains. Need more moss too
Anyways, some pics
and a FTS
