Both men fronted the Ballarat Magistrates' Court for a filing hearing on Tuesday afternoon charged with a number of offences, including cultivating a commercial quantity of cannabis.

Tuyen Hoang, 40, and Minh Phuc Vo, 19, briefly appeared before magistrate Cynthia Toose who remanded both men to reappear in court next year.

A lawyer representing the men told the court neither spoke English and had everything explained to them through a phone interpreter.

Ms Toose ordered both co-accused appear via videolink for a committal mention on March 16.

EARLIER: More than 300 cannabis plants, with an estimated street value of $600,000, were seized by police during a raid on Tuesday morning.

Ballarat Divisional Response Unit police raided a single-story Wiltshire Lane, Delacombe property at 4.30am and arrested two men from the western suburbs of Melbourne at the scene.

Sergeant Paul Fitzgerald believed a total of around 350 plants would be seized when the raid was completed this afternoon. 

“We arrested the males at the address at 4.30am this morning,” Sergeant Fitzgerald said.

“We were acting on information received from the public.” 

Sergeant Fitzgerald said police found a “full house” of plants, some which were mature.

“There were seven rooms, all with a hydroponic set-up,” Sergeant Fitzgerald said.

He said police had found false walls in property. 

An electrical bypass was also found and has since been attended to by Powercor.

Sergeant Fitzgerald said the scale and size of hydroponic set-ups in the Ballarat area meant police were determined to uncover the set-ups, seize the plants and arrest the offenders.

“This is a commercial set-up which poses a risk to the community – there is a chance that it could catch fire,” Sergeant Fitzgerald said.

“(These set-ups) can definitely be dangerous – you’ve got a mix of power, water and bypassing electricity.” 

Sergeant Fitzgerald said police believed there had been regular occupants at the address. 

“Blacked out windows, people coming and going at odd hours, a lack of activity at the address (are all indicators),” Sergeant FItzgerald said.

“If anyone has any concerns they should call Crime Stoppers.” 

The raid follows a number of others in the Ballarat area in recent months.
