A Launceston drug bust netted more than 2.5 kilograms of cannabis and eight hydroponically grown marijuana plants, a court has heard.
The drug trafficking trial of Michael Anthony Bell began this morning in Launceston's Supreme Court.
Mr Bell has pleaded not guilty to one count of trafficking a controlled plant between November 2012 and July 2013.
The court heard the Northern drug squad raided Mr Bell's South Launceston home last July.
Crown prosecutor Yolanda Prenc said the defendant led detectives to a shed containing the plants and a laundry storing the cannabis.
Ms Prenc said the cannabis was good quality and bagged in amounts commonly sold to drug users.
In her opening statement defence counsel Emily Judd said Mr Bell grew and used the cannabis but had no intention to sell it.
Under Tasmania's drug laws a person caught with a kilogram or more of cannabis is automatically deemed to be trafficking unless the defendant can prove otherwise.
The trial continues.
