Answer from a study in Canada:
“Rainfall of at least 25-30 inches per year.”
The information provided in this fact sheet is based on our 1995, 1996 and 1997 research data. Research data was collected from the test plots at Ridgetown College and the Kenex pre commercial field trials in Pain Court. The hemp research project at Ridgetown College has been sponsored by Kenex Ltd. Canada. Source: “Industrial Hemp: A Cropping Guide For Farmers”, Peter Dragla M.

For producing blossoms with high THC value
To generate optimum quantities of THC-containing resin, the plant needs a fertile soil and long hours of daylight. This means THC production for outdoor growth occurs optimally anywhere within 35° of the equator. Typical growing regions include Mexico, Nepal, Northern India, many parts of Africa, Afghanistan, the United States and Australia. [Wikipedia]
