Hey P! I've been looking into the HPS as i am new to growing and from what I've read, the 400w with passive air intake can be placed the closest with the most lumens. No, you can't get it as close as a 150 or 250, but you get more lumens from just a couple inches further away. I was reading a chart last night (and will try to find it) that had all of the wattages and the lumens/distance from plant. Looking good btw!
