Police recovered 60 cannabis plants after being called to support the fire service at a report of a house fire.
No one was in the property when the emergency services arrived and the fire was quickly put out by the fire service.
The neighbouring properties had to be evacuated but the residents were able to return a short time later.
An investigation is being carried out into the cause of the blaze, which happened in Birkin Avenue, Hyson Green, at 2.30am today (Saturday 17 April).
Officers found the cannabis plants on the first floor of the property, as well as hydroponic growing equipment and the electricity had been bypassed.
Chief Inspector Riz Khan, of Nottinghamshire Police, said: “Cannabis cultivation often leads to a number of risks to the community including the threat of fire which can impact on unsuspecting neighbours.
“We also know from experience that they can lead to burglaries and home invasions by criminals trying to steal the drugs.
“That is why community intelligence about cannabis cultivation is vital and people can be reassured we will act on this information to keep people safe.”
Anyone who witnessed anything suspicious in the area is urged to contact Nottinghamshire Police on 101, quoting incident number 88 of 17 April 2021.
