Least amount of equipment, easiest to set up is DWC.
You MUST be able to keep the res cool to 68F though. Any higher and you have to add non-nutrients to combat root rot. Huge hassle, compared to straight hydro.
Your main issue is going to be water transportation. I would recommend a couple 5 gallon jugs, a wheeled platform that will hold/roll them easily and submersible pumps, for pumping the water from jug to reservoir.
