A 42-year-old man faced the ACT Magistrates Court on Thursday after police seized about 300 cannabis plants and more than $20,000 in cash.
ACT Policing's criminal investigations team allegedly found the drugs and money when they executed a search warrant in Spence on Wednesday night. Officers were continuing to search the premises on Thursday.
The Melba man has been charged with drug and trafficking offences, including cultivating a commercial quantity of a controlled plant.
He was refused bail during an appearance in court on Thursday. He did not enter pleas.
The case is due back in court on July 5.
Anyone with any information about the manufacture, distribution or supply of illicit drugs is urged to contact Crime Stoppers on 1800 333 000, or via the Crime Stoppers ACT website. Information can be provided anonymously.
