Trays instead of individual pots for indoor growing??

Not a problem, you'll be giving us the answers after a few grows, no sweat.
I wanted to say, that a decent tray that people use for SOG to put about 6 plants in, and would probably work for you as well, is a kitty litter box with a couple dozen holes in the bottem.

I can't imagine it making any difference in that respect. What worries me is that there doesn't seem to be much room for rectifying any mistakes with nutes or PH probs. No way to flush.
It may suit someone who's as experienced as him more.

Yeah I'd have to agree. Tranobe has ultimate control over everything in that room and from what I remember he uses 100% healthy clones everytime. Its only really suitable when you have total control over your environment. In fact when you don't, and your growing on a smaller scale, like mentioned above, I think that you introduce more potential limitations as to what you can do to rectify any problems that may arise. You can't correct any toxicity or deficiency.
