I'd do both. I for one, soak Oli (my beloved Greek tort) daily, and twice/three times a day in the HOT weather. I live in Jordan (the Middle East), where the climate is that of a desert: very hot and DRY in Summer and freezing cold in Winter.
Please post pics of your tort and his enclosure, once you get your tort. And in the meantime, you could read the "Beginners Mistakes" Thread and the care sheets on RF torts.
