It really would depend on how smooth you want the action and what length you want the final video to be. I mean if you want the entire clip to only be 3 minutes, then you can space out the time between shots more. When I do night lapse shots, I tend to take a picture every 5 or 15 seconds. 5 seconds if there's a wind out and clouds are really moving, 15 seconds if it's calmer.
You can pick up a 128GB compatible memory card quite cheaply which will give you plenty of room for timelapse shots. Make sure you check this list before purchase: Recommended Memory Cards
You can always do a 1 day timelapse and at the end of the day, remove the memory card and see how much space you used up. You can then calculate how many day's total you can fit on the card.
