I have a 1 year old Sulcata - she is in a long garment/craft bin with crushed walnut (?) substrate. The walls are only about 6 -8 inches high. Has a reptile heat lamp and a shallow dish of water as well. Planning on putting her outside in an enclosure this summer, so more ideas on humidity...
So - how do you go about creating humidity? I soak my 1 year old probably 2-3 times per week and they have a heat lamp which she/he seems to love, but seems to be healthy - good appetite and quick growth. Just not sure how to add that!
