^^^^^I'm going to make a suggestion...Try reading about your new found hobby. I am not saying this to be mean, but you really need to have a basic understanding of growing before you attempt to grow. There are HUNDREDS of marijuana website online that have FAQ'S sections to answer the very same questions you ask. If you try to learn while you are growing you will get frustrated and give up because you won't know how to even begin to asses certain problems that will occur while you are a new grower.
aside from that, get some dirt and put some seeds in it, water once or twice a week.you might get lucky. try the foxfarm ocean forest it rocks.
thinks i just needed to know the watering time. so its once - 2 times a week? i wanna train my next plant to look like a small bush kinda like the photos here.
the best way to know when it needs water is to lift the pot. see how heavy it is after watering.a lot depends on the strain and amount of soil you have it in. i have five gallon growbags i only water every two-three weeks,two and three gallon bags i water more like once a week. two or three times is for starting seeds in a cup the first week, it needs to be moist all the time but not soaking wet. indoors you water much less than outdoors in the ground.
