Summoned to a house Sunday morning because of an argument over drugs, New Port Richey police made a much bigger discovery: a sophisticated growing room for marijuana plants inside a house, reports said.

Officer Chris Trapnell went to 5053 Hillside Drive at 11:40 a.m. Sunday to investigate an argument involving drugs. There, Trapnell found Richard Lubanski, 38, who lived at the Hillside Drive home.

Lubanski, according to his arrest report, admitted to having a “small amount” of marijuana in the house, Trapnell said. Lubanski then unlocked a bedroom door, revealing a “grow room.”

In the room were a carbon dioxide machine, ozone generator, a motorized tract lighting system and walls lined with reflective materials. On the floor were 45 marijuana plants, each about 3 feet tall.

Lubanski, according to his arrest report, said he was growing the marijuana to sell.

Lubanski was taken to the Land O’Lakes jail, facing 45 counts of cultivating marijuana and one count of possessing drug paraphernalia. He was being held Monday evening on $100,500 bail.
