Police have burned a large pile of cannabis, after finding more than 11,000 plants during raids on three properties west of Brisbane.

The Queensland drug squad uncovered 11,795 cannabis plants when they raided properties in Coominya, Mount Hallen and Churchable yesterday.

They also discovered "sophisticated hydroponic grow houses", which contained plants ranging from seedlings to 1.5m-tall bushes.

Drug products in different stages of the drying process were also found, police said.

Officers found two men, aged 24 and 26, in the Coominya raid, and they have each been charged with producing dangerous drugs.

Drug squad Detective Superintendent Jon Wacker said the seizure would have a major impact on Brisbane and south-east Queensland drug markets.

"Prior to the execution of yesterday's search warrants, investigations throughout Operation Papa Cider had already netted the arrest of seven people on 10 charges and the seizure of approximately 87kg of cannabis," he said.

"The estimated value of cannabis seized throughout this operation to date stands at approximately $60 million."
