Grow-op
Extracted from the Wikipedia article Cannabis cultivation.
Popularity and extent
Indoor growing became increasingly common when equipment, seeds and instructions on how to cultivate became widely available. So-called grow-ops (growing operations, often located in grow houses) are seen by many marijuana enthusiasts as a much cheaper way to gain a steady, higher-quality supply of cannabis. On a larger scale they have proven a viable commercial venture, with some law enforcement agencies finding grow-ops large enough to yield several kilograms (pounds) of cannabis. More expansive grow-ops are generally more susceptible to detection than smaller operations.
