The warm, sunny summer weather hasn't just been good for vegetable farmers, but also prime for growing marijuana, according to the RCMP.

Police found two outdoor grow-ops using a helicopter last month on the Avalon Peninsula.

One grow-op was on the edge of a residential area in Portugal Cove-St. Philip's. Police say about 12 plants were discovered — some as high as five feet.

Police also found 45 plants of similar height behind some homes near Bay Bulls-Big Pond on the Southern Shore Highway.

Meanwhile, an anonymous tip led the RCMP to another grow site in New-Wes-Valley where 21 plants were found and seized.

Police are investigating. No charges have been laid yet.
