If you're a legal OP then I would ditch the trailer idea and build a greenhouse. The steel trailer is not the easiest place to grow. A Greenhouse will allow way more environment control and save a ton on the power costs. If you have no grow experiences than I would go with something simpler than NFT, till you have a few strains and experience under your hat.
If you are set on NFT, you better read more as your equipment list is way to short.

Best of luck keep us posted on your progress.

Hydro seems like the most efficient method space and time wise. I did want to know what would be the best hydro system for this setup. There is a guy in my town that professionally builds grow rooms, so that is an option. I live on Vancouver Island to give you an idea of the climate. An idea for room layout: Rating: 5
