I've had this dream aswell (like quite a few have I suspect), holland would be the obvious answer but there is a limit on plants there, remember you have seed banks that operate at least semi legally from holland (I'm pretty sure sensi seeds do it legally somehow I remember seeing it on a documentry about howard marks I think)

However I also did see a police raid in dam where they were busting someone for having way too many plants.

But hey someone has to supply the coffee shops with top quality marijuana and hashish, but it would be a costly procedure to set up a business with all the lighting ventilation etc and you say you're already pretty skint. Also I doubt your bank manager would give you a business loan to grow pot.

Why don't you see if you can get a job in one of the seed banks in canada or holland learn the trade etc.
