i have a 10 gallon tank witha screen lid - i found that humidity problems can be solved by using coconut fiber or cypress mulch as substrate and covering the entire lid with plastic wrap and cutting a small hole or two in the wrap t obring humidity to the level u want and also use a wide waterdish as it will allow more water to evaporate.
also its ull get more n better anwser if u make ur own thread![]()
