Puerto Rico police uncover island's biggest pot greenhouse

SAN JUAN, Puerto Rico -- Puerto Rico police said they raided the island's largest hydroponic marijuana greenhouse on Tuesday, with nearly 2,000 plants being grown in a former addiction treatment center.

Police Commissioner Antonio López Figueroa said officers discovered the greenhouse in the northern town of Carolina, just east of the capital of San Juan, after receiving a complaint about possible human trafficking. He said no one was found inside the three-story building.

Officials said the plants were nearly six feet (two meters) tall, and that additional marijuana had been packed and was ready for distribution. They said they also found weapons at the site.
