Grow houses that produce marijuana are being built across Oklahoma, often in old industrial buildings, and the revival of the properties is adding to the economic boost being provided by pot.

“It's leased up a ton of retail, it's leased up a ton of warehouses and it's helped our market,” said David Chapman, an associate professor of finance and real estate at the University of Central Oklahoma.

Marijuana growing is done primarily indoors where elements such as water, air flow and light can be managed.

Large warehouses help growers meet the increasing demand for medical pot. Some retailers also are choosing to grow their own marijuana, allowing them to control the supply chain from seed to potted plant to marketable pot.
