Hemp plants are almost always cultivated outdoors, as opposed to marijuana plants, which are often planted in greenhouses or indoor grow operations. Because hemp is susceptible to the same predators, diseases, and insects that attack marijuana, many cultivators employ a technique called crop rotation, in which alternating crops are planted in the same place, to avoid any buildup of these organisms and to allow nutrients to return to the soil.
Hemp fibers are primarily used for textiles, paper, building materials, and other industrial products. Raw materials such as hurds, or shives, are short woody fibers typically found inside the stalk. They’re used for making bedding materials, absorbents, particleboard, ceiling panels, compost, and other industrial products.

How is hemp cultivated differently than marijuana?
Certain parts of the hemp plant are legal in Australia. The government has more information.
The 2014 Agricultural Act, more commonly known as the 2014 Farm Bill, includes section 7606, which allows for universities and state departments of agriculture to cultivate industrial hemp, as long as it is cultivated and used for research. Under the 2014 Agricultural act, state departments and universities must also be registered with their state, and defer to state laws and regulations for approval to grow hemp.
Many countries differentiate hemp from marijuana by the amount of THC produced by the plant. In the US, industrial hemp is defined as Cannabis sativa L. that does not contain more than 0.3% THC. The European Union has set the limit at 0.2%, while in the UK the limit is zero, unless growers have a cultivation license to grow industrial hemp with no more than 0.2% THC.
Hemp stalks are processed through decorticating, a multistep method for removing the long fibers from the rest of the plant. This can involve field retting, a process in which the plants are cut and laid out in the field for four to six weeks. During this time, any bacteria on the plant’s surface will break down the outer layer of the stalk. The retted stalks are then dried.
The main distinction that separates hemp seeds from cannabis seeds sits in the amounts of certain compounds, called cannabinoids, present within them. The 2018 Farm Bill established a limit of 0.3 percent THC content for any Cannabis sativa plant to be classified as hemp in the US – seeds included. Some local jurisdictions on the state level (and other regions of the world) have their own definition of what distinguishes hemp from cannabis. Still, this 0.3% THC content threshold is quickly becoming an accepted standard.
These seeds are essential both to the businesses and farmers who grow the cannabis crops and the consumers who use the many different varieties of cannabis products currently available. And while there are numerous methods to growing and producing the plant itself, the entire industry relies on the ability to use viable cannabis seeds obtained from a reputable and reliable source.
Another big difference between cannabis seeds and hemp seeds is cost. Since cannabis seeds are most often sold for purposes of growing cannabis plants, their seeds will typically cost you more than what you’d pay for hemp seeds at the grocery store. The rise of legal hemp and the CBD market has increased the value of hemp seeds a bit, but cannabis seeds will almost always cost considerably more.
Fueled by widespread acceptance and removal of regulations, the hemp and cannabis industries are growing rapidly across the globe. They may technically be the same plant from a scientific standpoint, but in lawmakers’ eyes, two classifications exist with their own set of rules and regulations. Understanding the difference between hemp and cannabis seeds is a critical step for anyone involved in these industries – from seed to sale.
Recent developments regarding hemp and cannabis regulations have expanded hemp from grocery shelves to alternative health clinics and corner stores across the country and beyond. Hemp oil has various uses and benefits (which is why people use cbd lotion, take it as a tincture, and use it in cooking, to name a few), while being the fuel behind the recent boom in the CBD market.
With the capabilities to produce crucial resources such as food, rope, clothing, paper, housing material, and more, hemp has been the catalyst for man’s earliest innovations.
“Marijuana” is a term used to classify varieties of Cannabis that contain more than 0.3% THC (by dry weight) and can induce psychotropic or euphoric effects on the user.
What is Hemp?
While the intoxicating properties of each plant is an important factor to consider, categorizing Cannabis as either hemp or marijuana based on a single characteristic presents a skewed portrayal of Cannabis which prevents users from fully understanding its diversity.
To summarize and re-clarify:
A common misconception about the 2018 Farm Bill is that it legalized CBD regardless of if it was derived from hemp or marijuana. This is not true.
