| Outside the baggy, I would guess every 4 days, but it depends on how fast the plantlet sucks the water out of the pot. But the best is to flex the pot and pull the rootball out just before watering and look at the moisture in the rootball. Then just slip the rootball back into the pot. The baggy is OK if you are sure it is sufficiently open. Still want a wet dry cycle, just a little slower.
