Questions about making my grow box.

[Aloha420]

Hi guys..I am thinking to start a grow journal in the next month or so and i will need your help..I have grown one time before and it did above average..
Now i am thinking to grow arjan's ultra haze#1,a pure sativa in ScrOG...I think i'm gonna have 4 of them.But I don't know much neither about the strain or the ScrOG method(about the scrog i know the basics reading the pinned topic about scrog).My question is in what average size should i make the screen for the plants?Any opinions of your past grows are welcome.And also do you think that a 600W HPS would work??Because it's the maximum i can use 'cause of the electricity bill...Or should i go for less plants-lets say 2??
Thanks
