The Solano County Sheriff's Office arrested a Vallejo man Wednesday on suspicion of growing more than 400 marijuana plants worth more than $40,000 in a northeast Vallejo residence.
Narcotics detectives served a search warrant at the residence in the 6000 block of Elkhorn Court after a four-month investigation prompted by an anonymous tip, according to the sheriff's office.
All but one door and a window were boarded up or fortified, and some interior walls were removed or reconstructed.
The 428 plants were in various stages of growth, and additional plants had already been harvested and removed, according to the sheriff's office.
Jason Johnson, 39, was inside the residence when the warrant was served, and he was arrested for cultivation of marijuana, possession of marijuana for sale and maintaining a place to sell, give away or use a controlled substance, according to the sheriff's office.
