Inside a corn field in Jackson County's Grass Lake Township Tuesday, police found 22 six to nine foot tall marijuana plants.
"Typically they do use farm land, corn fields, swampy areas that can't be accessed, and where people don't check that often," Lt. Tim Gill, commander of the First District Drug Task Force, said.
Gill said late September and October is harvest time, not for farmers, but for growers who are illegally planting and growing marijuana outdoors.
Thanks to a tip in Grass Lake, police caught the two men in charge of the marijuana grow there. Weeks ago, police issued the help of the National Guard to seize 1,700 illegal plants.
"State-wide the numbers are up significantly from last year and last year they were up significantly from the year before," Gill said.
Just last week in Ingham County, Sheriff's deputies discovered a marijuana grow operation in a field just off of Harper road. There they found 22 plants worth an estimated $40,000 on the street.
"It's a little too early yet to tie these seizures to the new medical marijuana law that was passed two years ago," Gill said, "but we are seeing a number of the operations we find, people have the registration card."
But that's not enough to avoid prosecution in most cases because the law states you must have the plants in an enclosed, secure area.
Gill said police are hoping for more tips from the public and hopes hunters will be of assistance in the next few weeks all across the state.
"It just means more people in the woods and areas where they might find these types of operations," he said.
Call police if you find anything suspicious.
According to the Drug Enforcement Administration, there have been more than 35,000 individual marijuana plants seized outdoors in Michigan through August of this year, which is more than all of the plants seized all of last year.
