well u still need and should have the inclosure up and running at least 4 or 5 days before u get the snake. that way u can make sure u will have the right temps/humidity. if u cant, well i sudjest you purchase the snake but leave it were it is for the next week untill u get everything setup. dont get offer anxious. your snake will be stressed out enough when u bring it home, so the last thing it needs is to not have the right invironment it is used to. If it does have what it needs, your snake will settle in faster, and then when u introduce its first meal u wont be wondering why it isnt eatting. good luck
