You will water until some comes out of the drainage holes. Make sure to dump all extra water out to prevent overwatering.
Make sure that the soil dries, thoroughly, down to about 2 or 3 inches between watering.

It is worth noting that only 1 pepper will grow in that container. There is going to be some careful work ahead of you, here.
You will need to thin out all but 1 pepper seedling. DO NOT pull them out. Snip them at the base. Pulling them out will disturb the roots of the one that you want to keep, and likely kill it. In the future, it is best to, only, plant one or 2 seeds and keep the strongest one to avoid having to do this tedious task.
