any fan is really fine, just helps build the stem stronger.
as for watering, im the same way. I want to water often. I have 4 plants and found the best way to water is just give a little bit once or twice a day. Especially if your lights put off heat. I just get a water bottle, and put like a 1/3 of a cup, usually once a day but sometimes twice.
I got a plant thats 25 days into flowering, one thats 7 days into flowering, another about 42 days old in a veg box, and my last one is about 23 days old in a veg box. And their doin great that way.
