Edwards Crescent in Wendouree has been raided by police for the second time in three years as another hydroponic cannabis grow house was uncovered in the quiet suburban street.

Detective Acting Senior Sergeant Brett Caddy of Ballarat police told The Courier a search warrant was executed at 8.30am on Monday at a house at 17 Edwards Crescent.

Police forensics officers, plain clothes and uniformed members were in attendance at the property.

More than 200 cannabis plants were found inside, with a value of over $1 million.

No arrests have been made, Detective Caddy said, and investigations are continuing.

Nobody was in the house at the time of yesterday's raid.

Detective Caddy said an extensive hydroponic system was in place throughout the home. He said the house's electrical supply had been illegally bypassed, and the presence of Powercor employees was a safety measure for police and the public.

Powercor workers were at the site disconnecting the mains and ensuring the house was safe.

A sign on the door warned against entry due to electrical danger.
