Humid hides with moss and sprayed intermittently, humid retaining substrate like 100% cypress mulch or Repti bark are helpful. Covering the top screen with foil or a dampened towel also help. When I had glass enclosures I used a "versa top". A folding glass top perfectly constructed to fit standard tanks based on the gallon capacity. They are commercially available at Petco, Petland and Petsmart. Humidity issues will get resolved right away. Versa tops also will increase your ambient temps.
