You Ray I like your set up.
But I do have a few ideas for you.
First off to get full potential from a 400w HPS, it needs to be about 12 inches from the canopy. Looking at your pic it will need to come down about a foot. You'll need to get some light yo-yos or some rope ratchets so you can raise/lower your lights. Don’t use chains they are a big hassle, plus they add hella weight.
And second you need an oscillating fan to keep the air moving.
One question Ray, do you plan on flowering them inside or when spring comes around will you throw them outside?
If you plan on doing everything inside, you'll need more plant growing space. You might have to take your containers off throes racks and put them on the growing. Also a 400w doesn't enough light penetration to grow a full size plant. A 400w HPS has 80cm(31.5 inches) of light penetration. I don’t think your growing Patios, so I’m sure they'll be bigger than 2 feet.
