If your going with hydro I wouldn't start your seeds in jiffy peat pellets. Also, would get some hydroton or something similar instead of using verm and perlite. Verm and perlite are good for hempy style where you water them like you would with soil, but in a DWC I foresee quite a few different problems. One being root rot as the verm will hold so much water it will be constantly saturated and thats not a good thing. As for nutes, seems general hydroponics is well liked.

Dont use 800 watts of lighting on two plants. Thats just wasting electricity,bulbs,ballast,etc etc. 400 watts is fine for 2 plants. Yes the plants would benefit from both spectrums, but with such a small scale grow the differences would be nill.

From my understanding, in a DWC setup the actual medium that the root ball sits in is actually above the water. So that being said, how would the vermiculite remain completely saturated and hence created root rot?
In addition, if he used a ratio of something like 1:3 or 1:4 verm to perl, wouldn't that be a way to counter the over saturation?
The only reason I'm throwing these question at you is because in my Ebb and flow setup, my plants sat in a verm and perlite medium. The thing flooded every 3 hours for 30 minutes and I did not have an issue at all. In fact, when I removed the plants and took them out of the cups, the roots in the medium were more white and healthy looking than the roots that sat outside of the medium.
I do not see any problems in using vermiculite and perlite as your hydroponic medium.
Well I figured the verm would be saturated because the verm draws moisture in and holds it and releases it. But if it has a constant humid environment underneath it then it would probably stay saturated. I wouldn't do it if it were me as I try not to make mistakes when first starting at new things. And hydroton is fairly affordable. If anything just use perlite in a DWC not verm.

I disagree. I think the increased UVB would result in a much higher quality product.
For two plants to run 800 watts of power is entire overkill and a waste of resources. It's not going to result in too much more product and it's not going to be drastically better then just using a 400 watter.
edit* Not to mention it looks like a fairly small sized grow, so having two 400 watt lights also brings up the heat in a small area. To run TWO lights for this small of a setup would not benefit you to the point of being worth it.

Well, for 5X5 I would in fact use two 400 watters if you did have them. Are you going to enclose the area or keep it at 5X5?
