Industrial hemp is one of the most useful plants a farmer can put in the ground, and most people have no idea how many things it turns into. The same crop we grow on our USDA Organic farm in Wilmore, Kentucky can become rope, fabric, animal bedding, hemp hearts, cooking oil, insulation, paper, and the CBD-rich flower we hand-trim every fall. One plant, dozens of finished products, and almost none of it ends up as waste.
That range is why the industrial hemp industry keeps growing even when individual product categories rise and fall. We've been farming hemp here since 2018, and this is a plain look at what industrial hemp is, how it's different from marijuana, where it's legal, what it's made into, and why it's such a forgiving crop to grow.
What Industrial Hemp Actually Is
Industrial hemp is Cannabis sativa L. grown for fiber, grain, seed, or cannabinoids rather than for intoxication. Legally, the line is simple: a hemp plant tests at or below 0.3% Delta-9 THC on a dry weight basis. Anything above that is marijuana under federal law. Same species, different job.
The plant is tall and fast. According to the Agricultural Marketing Resource Center, industrial hemp reaches 6 to 15 feet and matures in roughly 70 to 140 days depending on the variety and the weather. A fiber crop gets planted dense so the stalks grow straight and thin. A grain crop gets more room. The CBD flower we grow is spaced even wider and tended more like a garden than a field, because the value is in the resin-coated buds, not the stalk.
It helps to picture the plant in three parts, because each one feeds a different business. The stalk splits into long outer fibers and a woody inner core. The seed becomes food and oil. The flower carries the cannabinoids. A farmer decides which of those three to chase before the seed ever goes in the ground, and the variety, the spacing, and the harvest timing all change based on that choice. That's why one hemp field can look nothing like the next.
Industrial Hemp vs Marijuana
People mix these up constantly, so here's the short version. Hemp and marijuana are the same plant species. What separates them is THC content and what the plant is bred to produce.
Hemp stays under 0.3% Delta-9 THC, which is too low to get anyone high. Marijuana is bred for high THC and commonly tests anywhere from 10% to 30%. Industrial hemp varieties are bred for the opposite traits: long fiber, heavy seed set, or high CBD and CBG with the THC kept legal. When we send a batch to the lab, the Certificate of Analysis confirms the Delta-9 number before anything ships.
Is Industrial Hemp Legal in the US?
Yes. The 2018 Farm Bill, signed as Public Law 115-334, removed hemp from the Controlled Substances Act and defined it as cannabis containing no more than 0.3% Delta-9 THC by dry weight. That single change is what turned hemp from a research curiosity back into a real American crop.
Growing it still takes a license. We farm under Kentucky's hemp program, and every licensed grower has to register their acreage and test their crop before harvest. The rules around fiber and grain may loosen further: in 2026 the House Committee on Agriculture advanced the Farm, Food, and National Security Act, which aims to treat industrial hemp grown for fiber and grain separately from the cannabinoid side of the business. For a fiber farmer, less paperwork on a stalk crop that can't get anyone high is a welcome change.
What the Industrial Hemp Industry Makes
This is where hemp earns the word versatile. The stalk, the seed, and the flower each feed a different supply chain.
Fiber
The outer stalk gives long bast fibers, and the woody core gives short hurd. According to the National Hemp Association, hemp fiber goes into cloth, rope, animal bedding, paper, packaging, pressed plastics, biofuel, concrete additives, and even spill cleanup material. Fiber is the fastest-growing slice of the field-crop side right now. The USDA's National Agricultural Statistics Service reported that hemp grown in the open for fiber covered 18,855 acres in 2024, up 56% from the year before, and produced 60.4 million pounds, up 23%.
Getting from a standing stalk to usable fiber takes a couple of steps that most people never see. After the stalk is cut, it's left in the field to ret, which means the dew and microbes loosen the bond between the bast fiber and the woody core. Then a decorticator separates the two. The long bast goes toward textiles and rope, and the hurd goes toward bedding, hempcrete, and paper. For decades the missing piece in the United States wasn't farmers willing to grow fiber, it was the decortication and processing plants to handle it. That gap is finally starting to close, which is the real reason the fiber acreage numbers are climbing.
Grain and Seed
Hemp seed is food. Hulled seeds become hemp hearts, and pressed seed becomes cooking oil and protein meal. The numbers are striking per acre. The Agricultural Marketing Resource Center estimates that an acre of grain hemp yields about 700 pounds of grain, which presses into roughly 22 gallons of oil and 530 pounds of meal. That same acre also drops about 5,300 pounds of straw that can be turned into around 1,300 pounds of fiber. A dual-purpose crop pays the farmer twice.
CBD and Hemp Flower
The part of the plant we're known for is the flower. The buds carry the cannabinoids, CBD and CBG mostly, plus the terpenes that give each strain its smell. We grow strains like Hawaiian Haze, Orange Gas, Mothership, and CBG White, hand-trim each batch, and lab-test it before it leaves the farm. If you want to see what farm-direct buds look like, our CBD hemp flower is harvested and trimmed here in Wilmore. The same flower is also where extracted CBD oil starts before it's pressed and bottled.
Strain matters as much here as it does with wine grapes. Hawaiian Haze leans bright and citrusy, Orange Gas is heavier and sweeter, and CBG White is a high-CBG cultivar with its own chemistry. We pick what to plant based on what the buds will become and how they smell, then track the cannabinoid numbers week by week as harvest gets close. Pull too early and the CBD is low. Pull too late and the THC can creep over the legal line. That window is the whole game for a flower crop.
Building Materials and Bioplastics
The woody hurd mixed with lime makes hempcrete, a breathable insulation that's been used in walls across Europe for decades. Hemp also goes into fiberboard, packaging, and plant-based plastics. None of this is new. Hemp paper and hemp rope predate the United States. What's new is the processing capacity catching up so American farmers can actually sell a fiber crop again.
Two Industries Growing From One Plant
It's worth understanding that the hemp business is really two businesses wearing the same name. One side is the fiber and grain crop, grown by the acre, harvested by machine, and sold into textiles, food, and construction. The other side is the cannabinoid crop, grown for CBD and CBG, tended closer to a vegetable garden, and sold as flower, oil, and gummies. They share a plant and a legal definition, but the farms, the equipment, and the buyers barely overlap.
That split is exactly what the 2026 Farm Bill proposal is trying to formalize. A fiber stalk that can't get anyone high doesn't need the same testing burden as a resin-heavy flower, and treating them the same has held back the fiber side for years. We grow on the cannabinoid side, so the day-to-day testing is part of our normal routine. But we'd rather the fiber farmers down the road got to operate under rules that fit what they actually grow.
Why Hemp Earns Its Reputation as a Sustainable Crop
Hemp is a low-input plant, and that's the honest reason it gets called sustainable. It grows fast and dense, which shades out most weeds and cuts the need for herbicides. Its deep taproot breaks up compacted soil and pulls water from lower down, so on our ground it handles a dry stretch better than a lot of row crops.
It also works as a rotation crop. Drop hemp into a rotation with corn or soybeans and the deep root and heavy leaf litter leave the ground in better shape for the next planting, while the dense canopy means you're not spraying as much to keep weeds down. On a certified organic operation like ours, where synthetic herbicides aren't an option at all, that natural weed suppression is a practical benefit, not a talking point.
Hemp also takes up contaminants from soil, a process researchers call phytoremediation, which is why it's been studied on damaged land. And because the plant builds so much biomass in a single season, it captures a real amount of carbon while it grows. How much of that carbon stays locked up depends on what the stalk becomes: a hempcrete wall holds it for the life of the building, while biofuel releases it again. We don't sell carbon credits and we won't pretend hemp fixes the climate by itself. It's just a genuinely efficient crop, and that matters on a working farm.
How Hemp Is Farmed in America
Kentucky has grown hemp for a long time. In 1850 the state produced about 40,000 tons of it, and the modern program restarted small, at 33 acres in 2014, before the 2018 Farm Bill opened it nationwide. Our climate suits the crop: long warm summers, 40 to 50 inches of rain a year, and a frost-free window that runs roughly May through October.
On our farm, a season starts with certified seed and tested soil. Fiber and grain crops get harvested by machine. The CBD flower is the slow part. We watch the cannabinoid numbers as the buds mature, harvest by hand when the resin is right, hang the plants to dry, then hand-trim and lab-test each batch. The USDA Organic certification on that flower isn't a sticker we bought. It's a federal audit of our seed sources, our soil inputs, and our handling, renewed every year.
The industry as a whole is still finding its footing. The USDA valued the 2024 industrial hemp crop at $445 million, up 40% from 2023, with floral hemp making up most of that value and fiber a smaller but fast-growing share. Vote Hemp put total US retail sales of hemp products at $4.6 billion back in 2020. The market moves in waves, but the plant's range keeps it alive.
Buying Hemp Direct From a Kentucky Farm
Most CBD you'll find online passed through a broker, a white-label packer, and a marketing company before it reached you. Ours doesn't. We grow it, trim it, test it, and ship it from the same farm. Orders placed before 2 PM Eastern on in-stock items ship the same day, and the COA for your batch is posted publicly. If you've never bought hemp straight from the people who grew it, this season's Hawaiian Haze is a good place to start.

Frequently Asked Questions
Is industrial hemp the same plant as marijuana?
They're the same species, Cannabis sativa L., but bred for different jobs. Industrial hemp tests at or below 0.3% Delta-9 THC by dry weight, while marijuana is bred for high THC. The legal line is that THC number, not the plant family.
What is industrial hemp used for?
The stalk becomes fiber for rope, fabric, paper, animal bedding, and hempcrete. The seed becomes hemp hearts, cooking oil, and protein meal. The flower carries cannabinoids like CBD and CBG. One crop feeds three separate supply chains.
Is it legal to grow industrial hemp in the United States?
Yes. The 2018 Farm Bill removed hemp from the Controlled Substances Act and defined it as cannabis with no more than 0.3% Delta-9 THC. Growers still need a license and have to register acreage and test the crop before harvest.
Does industrial hemp get you high?
No. At or below 0.3% Delta-9 THC, the THC level is too low to cause intoxication. That cap is exactly what separates hemp from marijuana under federal law.
