The Union: The business behind getting high.
It's about an hour an a half long... The part that may help you out some is where they are talking about how The Union works. It's not the 'end all be all' guide that I think you're looking for.. But, it does shed some light on how the big boys do it and some of the safeguards they have in place.
Don't ever let anyone know that you grow... At best, for business reasons... "you know a guy who knows a guy".
You are looking at going down a path that I personally would never have the balls to go down. But, there are people out there that can and do pull it off every single day. Though most of the people that I've come across on R.U.I. grow for personal consumption... Some grow on a very large scale. You'll know the ones... They'll have several thousands of watts worth of lights and hundred plants. Hypothetically, if for whatever reason I 'had' to make some quick money by selling... I'd sell all of my crop, but what I was going to smoke, to one person that already has a customer base and let them deal with the rest.
I'm by no means an expert and I can't imagine what being forced in to your situation is like... But, I can say with 100% certainty.... DON'T TELL ANYONE and research the hell out of every aspect of what you are planning on doing well before you do it.
Good luck and be safe.
