Grow room setup abit of help?

Hi

I've been reading alot out growing and think I have the no how just to grow a few plants to see how it turns out.

I have HPS 400Watt Lamp coming and my Female seeds. Im going to use a wardrope and put fans everything I need to grow?

Does anyone know a site I could buy the stuff to build that would deliver to Ireland I know people always ask this sorry buy hydro and all them dont deliver to Ireland?

I know this might be asking abit much but does anyone know a site where it shows you what to get then step by step on how to set it up, Im handy with my hands but I just wanna get it right?

Regards

Joe
