A Mira Mesa man is facing multiple charges in connection with a pot-growing operation that sparked a fire inside his home.

Police say Joshua Rasmussen, 28, was asleep inside the rental home when the fire broke out Sunday morning.

After the flames were put out, firefighters found more than 300 marijuana plants growing inside two rooms of the house. They also discovered cash and thousands of dollars worth of lights and equipment.

Investigators said the fire destroyed $50,000 in pot and caused $100,000 in damage to the house.
