More than 300 cannabis plants have been found at a house in Gloucester by officers investigating a burglary.
The haul is due to be incinerated, police said
It took detectives five hours to remove heat lamps and dehumidifying equipment at the address in Furlong Road.
Police believe the plants would have ended up being dried out and sold to children in the neighbourhood.
"I'm sure families in this area will be grateful this cannabis isn't being sold and that people aren't making money from selling it," Insp Cooper said.
The plants were taken away by officers to be incinerated.
