Give it some time to left the springtails do their job and get the substrate going. As for lights, I did one 24inch 6500K florescent and thinking I need two at least. Gonna plan on adding another this coming week.

I saw the moss on Josh's website and it looks like nice stuff.
I'll try to call Black Jungle tomorrow and see what they know on adding additional nozzles to the Monsoon and I'll let you know what I find out. I miss some areas in my 20Long with just two nozzles.
