Getting a Savannah Monitor is this a good Temp tank?

[Zosime]

This is going to be a temp tank for a baby savannah monitor for maybe 1-2 months its a 29 gallon, i have 1 foot of sandy soil, a basking spot of 135-150 ambient temps 70-80, i have a humidifyer for the humidity and it stays at a constant 65-80, I have acoupe coark bark logs in the back left cornor so he can go in there to cool off if he wants. Let me know if you think its good or bad ill be getting the sav in like 1-2 weeks then ill be able to build the 7x4x4 enclsoure when i move then it will go in there so that will hopfully be done in 1 month if not 2 months tops.
