Looks good. I would think with good light you could water once a week if the soil is fast-draining, or once every two weeks if less so. Cloudy days might count as half a day in that general scheme. Water well, and make sure the plant is not sitting in water afterwards.
Time your repotting (whenever it does occur) to coincide with when you think the soil is going dry, around the time you might otherwise be watering, so you can have easy visual confirmation of the moisture in the soil. That's like an info freebie which can help you time the watering cycle down the road so your plant stays in the zone. I have never grown one of these but they are pretty awesome when they get big, and quite unique being from Hawaii.
