More and more countries are allowing the use and cultivation of marijuana for medicinal purposes. If you have a prescription for medical marijuana but cannot find a source, or if you simply want to save money, you may want to grow your own. Or, you might want to go into the business of selling medicinal marijuana. Either way, you’ll need to check to see if it is legal to grow marijuana, pick the right strain, decide on how you will grow it (outdoors, indoors in soil, or hydroponically), and then harvest and cure your crop.

As the cannabis industry expands, the role of good science within it will also expand, and there will be further opportunities for collaboration. “More and more,” says Zheng, “the scientific community and industry are directly communicating and sharing information.”

“Cannabis is just another crop,” he says. “The commercial flower and vegetable industries have been working on the same problems for many years, and they have the technology already.”

For years, the popular image of cannabis growers has been scruffy hippies getting high on their own supply in a disorganized underground economy, rather than shiny white industrial agriculture facilities. Even larger-scale operations involved minimal quality control or lacked formal record keeping.

Many of the challenges of large-scale cannabis production can be solved by drawing on the experience of the commercial greenhouse industry, says Zheng. Growing crops commercially requires a homogenous soil and consistent irrigation. Small variations can mean that parts of the crop dry out at different rates, which leads to the spread of pathogenic agents and root rot, and to an inconsistent product. But the tomato industry, for example, has experience of growing tens to hundreds of hectares of produce at a time, and that expertise can be transferred easily to cannabis growers, says Zheng.

Testing, testing

In the United Kingdom, for example, strict rules concerning THC levels in medical cannabis mean that labs can find it difficult to get the sample analytical standards that they need for comparing products. The licences required to handle the standards are the same as those needed by a lab doing research on the drug itself. “It’s ludicrous that analytical standards are so tightly controlled,” says James. “The cannabis products are treated the same as a kilo of cocaine.”

To run these advanced facilities, cannabis companies need researchers who are experienced in plant science, microbiology, chemistry and other scientific disciplines — and they are turning to academia to find them. “Instead of underground growers, they are hiring lots of university-educated and trained people,” says Zheng.

Cannabis analytical labs are becoming more professional. “I’ve seen an evolution in the sophistication of the industry,” Brauninger says. “Most of the people running labs now have PhDs and experience in the pharmaceutical industry. It’s light years more sophisticated than five or six years ago.”

“Because of the federal strictures, there weren’t any standardized methods. Labs had to validate everything themselves,” Brauninger says. “It’s difficult to bring in expertise when there isn’t a wealth of information available, and no trade association to help share techniques.”
