which system for basement kitchen garden, and spring seed starting?

[twd000]

I live in New Hampshire and garden outdoors during the six months of warm weather. I'm looking at setting up a hydroponic system for the six cold months. I mainly want to grow leafy greens and herbs for a family of four. I would also like to use the same system in the spring for starting seeds for the outdoor garden. I currently have a T5 grow light for the seedlings and I hand-water. The system will live in my finished basement and I would empty it each spring and restart it each fall when the cold weather halts work in the outdoor garden.

In addition to the grow light, I have a plastic shelf : http://www.lowes.com/pd_339949-230-3...lue+hawk+shelf
automatic timers, etc that I would re-use for the hydro system.
I have a Milwaukee pH meter and air pump from homebrewing beer.
I am an engineer and fairly handy at DIY.

Would an NFT or DWC hydro system be more appropriate for these purposes?

Conventional or organic nutrients? I also run a red worm composting bin - can I use the leachate in a hydroponic system?

I would be interested in growing leafy green stuff, not really fruiting and blooming (although strawberries would be nice one day)

Lettuce (romaine, Bibb, arugula, mesclun)
Napa cabbage
Kale
Basil
Rosemary
