Great job! and congrats , After the week is up try a f/t but make sure it is thawed/warmed enough. I keep one of guys in a 40g long, it was the tank that came with him..her and have never had a prob with temp/hum and I only use 1 uth, but I'm in so fl so that helps alot.
I'm in ND. Humidity is scarce to say the least. I have a humidifier for my room, so it stays around 40%, so getting to 50-60% with plants/wood/eco earth isn't too hard. I'm getting sick of eco earth already though.
