While there is excitement about the potential for hemp, the industry still needs a supply of seeds and varieties that suit different regions and purposes.
Northern Rivers Hemp Association president and NSW hemp breeder Andrew Kavasilas has been working on breeding varieties that yield a lot of seeds but can be easily harvested with machinery.
Andrew Kavasilas has developed new varieties of low THC hemp for use in fibre production and growing seeds for human consumption.

"We've got shorter varieties that are producing all their seed at the top of the plant [which] we can take off," he said.
"We'll concentrate on developing a Northern Rivers variety, but if we can produce high yielding plants with a lot of omegas we'll be really happy."
Once the varieties are developed, farmers will still be hesitant to grow hemp unless the price is right.
Mr Doyle said the price was currently $3.50 to $4.00 a kilogram, cleaned and graded.
That compares pretty well to wheat, but hemp has a long way to go to match the wheat or cotton industry in growers' eyes.
Despite that, Mr Kavasilas believes the value of hemp seed production in Australia could be $1 billion inside a decade.
"When you look to the Canadians, they went from zero in 2002 to about half a billion dollars in 2014," he said.
