Autoflowering plants

Ok so im bout to get my beans in a couple of days. im new to growing by the way. I got ak-47 autoflower beans feminized. now im only going to grow 5 plants at a time and i plan on growing them in my closet. I just need to know if a 200 watt bulb would work for 5 auto plants. How often should i feed them nutri and what nutri should i be using. Can i pick up the nutri at any local store like walmart.
