Needing advice on my first grow.

Ok guys Im getting ready for my first grow and want to do it right and i need a little advice. Fist off I am going to use the super silver haze auto. strain. I will be growing 10 plants and will be building my own grow box. I was planing on making the box 4ft long, 3ft wide and 3ft tall. I have done some research and want to use led lights because of the low energy cost. My questions are 1. how many lights would i need and what watts? 2. What size should my vent holes be? 3. Would this box be big enough for 10 plants? 4. What type of nutrients would i need to use? I know its a lot to ask but like I said I want to do this right. Thanks guys
