Text from an Jan 22, 2016 interview with Dr. Mike Dixon, director of the CESRF in the Waterloo Region Record;

 

There are many variations on the theme of growing pot, but no standardized method. Perfecting and standardizing production and quality is necessary if cannabis is to attain the stature of a high quality pharmaceutical commodity. 

 

Gaining the capacity to grow the same drug every time is absolutely necessary, he said. And while there are strong genetics available to do that, the only way to produce a systematic, standardized product is through using repeatable, high quality environmental controls. Dixon said no one has achieved it yet. The task is a big one. 

 

"The plain truth is that the environment controlled recipe, comprised of light intensity, light quality, temperature, humidity, nutrients, soil attributes … that recipe for specific commodities does not exist," he said. 

 

"Every grower spawn by the decades of underground growing has their own recipe, but very little of it is proven in the cauldron of scientific research, with controlled experiments and objective assessments of the outcome, and detailed analysis of the medicinal compounds," he said.
