The video did help investigators determine what time the fire started, just before 11:00 p.m. last night.
It took crews about an hour to get the fire contained; they had trouble getting water to it.
The nursery is tucked away at the back of a huge piece of property filled with greenhouses along Highway 92 in Half Moon Bay.
Bay City Flowers is renting the property but was not renting the abandoned greenhouses that burned. The property owner was not available to comment.
