After growing for 20+ years I only smoke about a gram a day to be honest, all I have time for, not sitting on my ass smoking weed all day.
His list is pretty good. You really only need the smallest lights they got out there, anything around 250 watts or up. I like good quality LED, a little more expensive to start with but saves you in the long run. Once you got your light and tent you have to think about ventilation. Focus on the ability to keep your tent within the environmental range you need and you will have success.
