And humidity,do I need to measure it and if so what should it be? here is a pic.



The top is usually covered, this is an 8 month old set up.

Thanks for the replys.
They get 12 hrs. from a compact flood light,and is close to a window to get some sun light,amount of sun would depend on the season.

Just to reinforce: No, there's no need to add a powerhead or any other measure for water circulation. All my set-ups are fine without current unless this is specifically needed for fish or any other critters inhabiting the tank.

Humidity seems to be fine, too. It may be more a matter of personal preference wether you head for close to 100% or more like 80% (or anything in between).

Your plants look healthy. Nutrients seem to be on the low side - you may want to experiment with adding very small amounts of (good quality) fertilizer.
