Eight different varieties of medicinal cannabis are being grown by the NSW government in a high-security facility in a secret regional location.
The NSW government was the first in Australia to receive commonwealth permission to cultivate medicinal cannabis, and is now working out the best growing conditions for the crop.
The research is being conducted in a top secret, $2 million state-of-the art facility in rural NSW.
Agriculture Minister Adam Marshall said the government was working to develop farming practices that ensured the cannabis could be produced year-round.
"Our aim is to determine the best growing conditions to produce the safest and most useful crops for patients," Mr Marshall said in a statement.
