New to growing

[Skiing Arab]

Hey, im Luke, 16 and from the UK.
Ive got a 600watt HPS light on the way (son t agro bulb) and im going to be growing in soil with fertilizer. Ive grown once before and only got around 1/2oz of skunk off it, but the light was pritty shit, the closet wasn't vented propperly and i didnt really know much about growing weed except when to harvest and simple shit like that.
This time ive got more of an idea and im going to invest with some white widow seeds , but still i could do with a couple of tips on how to get a nice large yield. (only aloud to grow a plant at a time so the more i can get off the better)

Cheers, Luke

Look up information about low stress training, topping, and screen of green (Scrog). All are ways of making short, bushy, higher yielding single plants good for growing a large plant indoors where height is the main size issue. But you should probably start at least two plants, cause you want to at least increase your odds of having a female. Good luck man.
