A marijuana grow operation went up in flames in an industrial part of Denver Tuesday morning.
Firefighters are now investigating.
Flames could be seen shooting through the roof as firefighters battled the blaze, which was concentrated to a building on 44th and Garfield. It's unknown how many plants burned.
The call came in around 5:30 a.m. and was extinguished in less than an hour.
