Police have seized more than 200 cannabis plants along with drug-related equipment from properties in Churcham and Bream.
The grows, estimated to be worth thousands of pounds, were discovered on Thursday 21 January after reports from members of the communities. Western Power had also alerted police after concerns about high levels of electricity being used at one of the locations.
They have now been dismantled after being made safe by electricians.
No arrests have been made and enquiries are on-going.
Inspector Nick Cook said: “Drugs can have a devastating impact on people’s lives and often go hand in hand with other types of criminality.
“We will continue to proactively target these operations and welcome any information you have about this kind of activity in the community. People coming and going at all times and properties with blacked out windows are just a couple of things to look out for.
“If you believe drug activity is taking place you can report this to us on our website or through Crimestoppers anonymously by calling 0800 555 111.”
