This particular T has made itself a pretty cosy hide, burrowed downwards. The dry coir substrate is 3-4". Temp is 78f day and 70f night. I never worry about or measure humidity but as with ALL my T's, it has a constant supply of 'fresh' clean water, which is 'slightly' overfilled as and when.
Otherwise they are a hardy species, great feeders and subsequently, fast growers.
