Da Cao was convicted of setting up pot-growing operations in a number of Lincoln homes.
A man accused of conspiring with his brothers to grow marijuana in Lincoln houses has been given 10 years in a federal prison.
Da Cao was sentenced last week. Cao must also serve five years of supervised release after he leaves prison.
Cao and two of his brothers were indicted for conspiring to grow marijuana. The Lincoln grow operation was discovered in 2010. Authorities say Da Cao paid utilities on a house where investigators found more than 1,400 plants.
His brother My Cao has been given two years in federal prison. Authorities say the other brother, Tham Cao, is believed to have returned to Vietnam.
