After weeks of watching a home near Morristown, Hamblen County sheriff's deputies say they went in and found several hundred marijuana plants growing along with gallons of marijuana "butter."
The sheriff says it's the most complex grow operation they've ever seen.
Multiple plant types were found, with values ranging from $1,600 to $1,800 a plant. Hundreds of plants were involved.
The butter is typically used in marijuana brownies or cookies.
Hamblen County Sheriff Esco Jarnagin said his office received a tip weeks ago.
They were able to get inside using a search warrant on Monday.
He said the grow operation was inside a vacant house on Brockwood Drive in an established subdivision.
"It all came out of the basement. It's a nightmare for the detectives to inventory all this stuff. We will be here all night," said Jarnagin.
Also inside of the house, was documentation and instructions for growing pot.
Officers say they took 32-year-old Keith Maewether into custody as a result of the bust.
Jarnagin thinks this bust will slow down pot distribution around the area for a while.
He said that "this was a main player."
