Michael Kohn, 47, was arrested Wednesday after Solano County Sheriff's Office narcotics officers executed search warrants at the two homes.
Sheriff's Officer Paula Toynbee said a sophisticated marijuana grow containing 31 mature marijuana plants and evidence of previously harvested marijuana plants were found in the basement of a home in the 100 block of Cypress Avenue in the unincorporated area of the county near Vallejo.
A residence in the 100 block of Newcastle Drive in Vallejo contained a marijuana grow site with 125 mature and young marijuana plants categorized by size in separate rooms, Toynbee said.
Narcotics officers also found evidence of sales, processed marijuana weighing 4 pounds 5 ounces, several firearms including two 9mm semi-automatic pistols, a .44-caliber semi-automatic pistol and a 9mm semi-automatic rifle, Toynbee said.
The estimated street value of the plants is about $780,000 and the value of the processed marijuana is valued at $21,750, Toynbee said.
Two young children living in the Newcastle Drive home were placed into the care of the county's Child Protective Services, Toynbee said.
Kohn is being held in the Solano County Jail under $59,998 bail and is to be arraigned at 1:30 p.m.
