Indoor/Vert farming Cannabis is very expensive - even with full auto-hydro/aero setups. And, after legalization there is huge downward pressure on PPK of the material (eg: -75-80%)

True, although that cost gives you the ability to control the environment very precisely. This allows for a level of quality that people are willing to pay for, at least when it comes to flower.

Not really (I say this after viewing the books for 100s of pot farms)

This is a genuine question - would you mind listing some of those crops?

Specifically, there's a number of states in the U.S. that allows people to legally grow marijuana / cannabis. I know it's still illegal at the Federal level, but that hasn't stopped people here in Washington state.

Plus, I was never the type of cool that knew a lot about drugs and alcohol. Computers, sure - I was definitely the type of cool that knew a lot about computers, but not so much the recreationally altered states.

Which has now come back to haunt me as I'm woefully ignorant of which crops might grow well in this sort of environment :)
