Every bottle of King Gee Full Spectrum starts as a plant in a paddock in the Northern Rivers of New South Wales, grown under licence by local farmers we work with directly. This post follows it the whole way, from seed to sealed bottle.
Why the Northern Rivers
The Northern Rivers sits on the remains of the Tweed shield volcano, which last erupted around 20 million years ago. What it left behind is some of the deepest, richest red volcanic soil in the country (krasnozem, if you want the technical name) and a subtropical climate with warm summers and reliable rainfall. It's why the region grows macadamias, coffee, avocados and, since New South Wales legalised industrial hemp cultivation under licence in 2008, hemp.
Hemp likes exactly what the region offers: deep soil it can push a tap root into, warmth, water and long summer days. Grown outdoors in those conditions, a hemp crop goes from seed to harvest in roughly four months.
Nimbin itself has a longer relationship with the plant than most Australian towns, and we're not going to pretend otherwise. But the hemp in our bottles is industrial hemp, grown under a NSW Department of Primary Industries licence from approved low-THC seed. The town gave us the name. The licence gives us the product.
Our growing partners
We don't own the paddocks. We work with a small network of local farmers in the Northern Rivers who follow organic principles and regenerative practices. We don't name them here. Their farms are their business, and a hemp crop in this region attracts attention it doesn't need.
What we can tell you is how they grow it. Between planting and harvest, the crop gets sun, rain, volcanic soil and not much else: no pesticides, no synthetic inputs. Hemp grows fast and dense enough to shade out most weeds on its own, which is one reason it suits growing clean.
Growing
Seed. Industrial hemp in NSW must be grown from approved low-THC varieties. That's a licence condition, and it's where the whole chain starts.
The season. Hemp is a warm-season crop. It goes in as the soil warms and comes out roughly four months later, by which time the plants stand well over head height. For oil, the part that matters is the flowering top and upper leaf, where the plant concentrates the compounds we extract.
Pre-harvest testing. Before harvest, the licence requires the crop to be sampled and tested to confirm it's under the legal THC threshold. This is a legal requirement, not a marketing step. The crop doesn't move until that result is in.
Harvest and drying
The flowering tops are cut and dried slowly, out of direct sun, until the moisture is low enough to store without mould. Slow on purpose: too much heat and the terpenes, the aromatic compounds that give a full spectrum oil its character, cook off.
Extraction
The dried plant is extracted with CO₂. Under pressure, carbon dioxide behaves like a liquid solvent: it's passed through the plant material, pulls out the oils and compounds, and then returns to a gas when the pressure is released, leaving a thick, dark extract with no solvent left behind.
For King Gee Full Spectrum, that extract is used as it comes, the whole plant's profile, unrefined, blended into cold-pressed Australian hemp seed oil: 3000 mg of extract in every 30 ml bottle. Our isolate-based products go a step further. The extract is refined until a single compound is left, and that's what goes into the oil. We explain the difference in Full spectrum vs isolate.
Testing
There are two checks between the paddock and the bottle. The first is the pre-harvest THC test the licence requires. The second is on the finished full spectrum extract: it goes to an accredited laboratory on the NSW–Queensland border, which measures its cannabinoid profile, including THC. The result is a certificate of analysis.
We don't post our certificates online. Lab reports get copied and passed off by other sellers, so we keep ours off the open web. If you'd like to see the certificate for King Gee, email us and ask.
Is hemp oil legal in Australia?
This comes up constantly, so here is the plain answer.
Hemp seed foods (seeds, seed oil, protein) have been legal to sell as food in Australia since November 2017, when Food Standards Australia New Zealand changed the Food Standards Code. That's why hemp seed oil is on supermarket shelves.
Growing hemp is legal under state licence. In NSW the licence comes from the Department of Primary Industries, and it requires approved low-THC seed and crop testing.
Hemp extract products sit in a more complicated space, and the rules depend on what's in the product and how it's sold. We sell ours as foods. We don't make therapeutic claims about them, and this blog won't either. What we will do is tell you what's in the bottle and where it came from.
Frequently asked questions
