BLUE TONGUE SKINKS

Hi everyone,

I have a terrarium with this dimensions 120x60x60.
What size/power bulb should I use? The seller said 75w but I fear it might not be enough.
Can anyone help?
Thank you in advance!

What is the enclosure made of? Is there ventilation on top or only on the sides?
75w isn’t too bad if it’s a glass enclosure. From my experience they’re not much different to a 100w just smaller. With wood and PVC you definitely need to go for a low wattage bulb, at least a 50w.
