Daya Foundation, Chile

Whether it's legal (think California, Colorado and a few other states) or illegal (think most other states) marijuana is a huge business with massive demand.

And that means plants. Lots and lots and lots and lots of plants...whether they're technically legal or not.

Colbin, Chile, is home to the largest legal marijuana field in Latin America. Opened in 2016, the farm, run by the Daya Foundation, is expecting its first harvest to bring in 1.5 metric tons of marijuana.
