He said while they had five children and a new born grandchild in the home, which they own, they kept the garage where the cannabis was grown permanently locked.
"The children have been shielded from this."
Mr Hard said it was a low level operation and when police searched the couple's home, Maru admitted the cannabis was grown for herself and her friends.
Judge Butler said 57 plants were found when police carried out a search warrant in December last year. In the garage, there were 12 potted plants, 20 seedlings and a grow room with 25 mature plants with an average height 18-24cms.
34 grams of dried cannabis was also found in the kitchen.
The couple had also tampered with the power board, rewiring it to bypass the meter reader, allowing them to steal an estimated $4000 of electricity for six months.
"Maru admitted selling it, Bak did not agree with it but he admitted tampering with the meter," said Judge Butler.
He said the couple had come under pressure from family and friends to expand the operation.
With Maru's previous good record and their guilty pleas, an electronically monitored bail sentence could work, rather than prison, the Judge said.
He sentenced Maru to three months' home detention, 200 hours of community work and ordered her to pay reparations of $4000.
Bak, a roadside breakdown callout worker, was sentenced to four months' community detention and subjected to a curfew of 8pm to 6am.
