Main Page | See live article | Alphabetical index A grow-op is a short term for a marijuana grow operation in which cannabis plants are grown in a (usually domestic) setting, often with the intent of creating large amounts of marijuana for commerical purposes. Grow-ops frequently make use of hydroponic technology to grow their plants indoors, and thus avoid suspicion. In many countries, grow-ops are illegal, and frequently disrupted by surprise police raids. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
