Our varieties
Performance-tested for Australian conditions.
Every HFA variety is selected for a specific end use, latitude band and growing window. Open a cultivar for its full profile, or compare all four side by side below.
01Ruby
Dual-purposeBred in the Bundaberg region in 1998. Sow September to November for a dual-purpose crop, January to March for a higher grain share, or May to August as a winter crop.
Ruby is an Australian industrial hemp cultivar bred in 1998 in the Bundaberg region of Queensland. As a dual-purpose variety it can be sown throughout Australia before Christmas (September to November) for a dual-purpose crop, or early in the year (January to March) for a higher percentage of grain relative to biomass. The winter sowing window runs from May to August, with a crop cycle of 80 to 95 days. Ruby has been grown successfully in rotation with other intensive crops, such as cotton and corn.

02King Gee 2
Fibre · hurdDeveloped in Australia in the 1990s. High biomass and late flowering make it well suited to fibre and hurd, reaching up to five metres.
King Gee 2 is an industrial hemp cultivar developed in Australia in the 1990s, known for its high biomass and late flowering traits, which make it well suited to fibre and hurd production. It can be planted between September and December and typically flowers in April, reaching up to five metres in height after around 90 days of growth. The cultivar performs well across diverse Australian climates, consistently producing strong fibre and hurd yields.
Best fit: Mixed cultivation environments and PFAS projects

03Woongarra Fibre +
Fibre · biomassA fibre line selected within our Farnsfield cultivar. Tall, high yielding and minimal branching, ready for harvest in roughly 120 days.
Woongarra is a unique fibre line identified within our Farnsfield cultivar. It emerged as a dominant, later flowering variety with strong phenotypic attributes: tall growth, high yield potential and minimal branching from the core stems. Woongarra is HFA’s fastest fibre production variety, reaching optimal yield and an ideal fibre-to-hurd composition for harvesting within approximately 120 days.

Agronomy guidance from experienced Australian hemp professionals: sowing rates, nutrition, weed control and crop monitoring through the season.
- Step 03
Plant with confidence
Quality seed backed by performance data, with ongoing support through to harvest and end-market pathways.
PFAS phytoremediation
A partnership built for real-world delivery.
PFAS are persistent by design and difficult to remediate. Through Phytogen Solutions, our joint venture with ENV Solutions, we pair HFA hemp genetics and agronomy with environmental delivery and C-Biotech’s licensed biological input. Every site needs its own technical, regulatory and operational assessment.
In C-Biotech’s Campus Vesta field trials in Belgium, a proportion of plots were brought below the Flemish remediation norm of 3.8 µg/kg dry matter, validated by SGS Belgium.
Australian field validation is in progress. We make no Australian efficacy claims until that work is complete.
