well watering is all depending on a lot of factors(temp, humidity, grow area size) I would be wrong to say 2-3 times a week when in fact it could be more or less....I mean as long as your not having problems with how your doing it now then you should be fine...Only thing I might add is I wouldn't let the soil completely dry, just when it starts to look more dry than wet...
