There is a good chance the 4M sq ft facility will become reality. Think about the situation Village Farm is in... they are currently profitable growing peppers, cucumber, tomatoes etc, and have the opportunity to switch from growing those to growing weed!! Profit margins are probably 10x higher. The way i see it, the only reason i can think of for them not to decide to convert all their operation from veggies to weed is if they have some sort of emotional attachment to partially keeping their business the way it is, say if perhaps to continue a family heritage. Aside from that, the clear business decision is to go all out weed growers.
