Crown prosecutor Hayley Sheridan suggested to Judge Christopher Harding that Allen should be jailed for at least four years.
"This was a sophisticated set-up, with separate areas overlapping growth cycles to ensure year-long supply of cannabis," she said.
Defence counsel Bill Nabney said the offending was less serious than the prosecution made out, operating primarily out of a garage, as the property was the couple's residential home.
Judge Harding said despite this argument, the home had been used as an instrument for criminal enterprise.
The nature and sophistication of the renovations made to the house to allow for the cannabis growing were evidence of this, he said.
Judge Harding also ordered the forfeiture of the $323,000 Cheyne Rd house to the courts.
