The Calaveras County Sheriff’s Office Wednesday afternoon arrested two Valley Springs residents at a large, unregistered indoor marijuana grow.

Members of the Calaveras County Sheriff’s Office Marijuana Enforcement Team served a search warrant on the 8400 block of Baldwin Street in Valley Springs and discovered that the entire home had been converted to a marijuana cultivation site.

More than 1,440 marijuana plants were seized, and a man and a woman identified as residents were contacted.

The Valley Springs man, Wenhai Yang, 52, and the woman, Xiugin Yang, 52, were both booked on suspicion of felonies keeping a place to sell a controlled substance and criminal conspiracy, and misdemeanor marijuana cultivation.

The arrests on Baldwin Street come about a month after a spate of illegal marijuana busts in the greater Valley Springs area; a spiderweb of avenues lined with mixed residential and commercial sites off of Highway 26.

In December, the Calaveras County Sheriff’s Office busted three Valley Springs unregistered indoor marijuana grows on the 6000 block of Hironymous Way, on Delin Way, and on the 10000 block of Milton Road.

In total, deputies seized and destroyed more than 3,000 marijuana plants at the homes, which were all configured for large-scale cannabis operations.

The Calaveras County Sheriff’s Office has warned of a trend where all the rooms in a home are converted for marijuana cultivation, and may not be occupied by residents or growers full time.
