One person is in custody, after police say they found a man growing marijuana in a trailer in his back yard.  Police haven't released his name. 

The bomb squad reportedly used a water cannon to destroy some of the explosives Tuesday.  They'll be back at the home again Wednesday.

Police reportedly describe the explosives as "home made."

The home was in a rural area, with no other homes nearby.  One home was reportedly evacuated as a precaution.
