Stay with HPS and a 400 will work great. I have the same size tent for my veg tent. I am using a 4ft 4 bulb T5 and it work as they first start growing but you'll want something more as they get bigger. I only veg my plants for about a month before switching to flower. And I'm still thinking I will get a MH light in there eventually. T5's work but not great... and LED's are too fucking expensive for not being any better.
