As part of the Agriculture Improvement Act of 2018 (aka the 2018 Farm Bill), the Hemp Farming Act of 2018 reclassified hemp (with less than 0.3% THC) from Schedule I, the federal government’s most restrictive classification of controlled substances, which are considered highly prone to abuse and without medicinal benefits. This move to federally legalize hemp allowed for its cultivation and distribution as a legal agricultural product.
Depending on the desired final product, hemp cultivars are chosen based on several factors, including:
CBD oil is extracted from hemp leaves and flowers. More and more people are experimenting with CBD oil extracted from hemp plants as a wellness supplement, hence the ever-growing popularity of CBD-focused cultivation.
Is hemp cultivation legal in the U.S.?
The whole hemp plant, from stalk to seed, can also be used to make fuel and feedstock. For more specific applications, hemp can be divided into four categories:

Hemp has been cultivated on a global scale for thousands of years. The oldest documented evidence of hemp cultivation is a rope, which dates back to 26,900 BCE, found in today’s Czech Republic.
Hemp was a prominent crop in the United States until 1937, when the Marihuana Tax Act virtually obliterated the American hemp industry. During World War II, the crop saw a resurgence in the US as it was used extensively to make military items including uniforms, canvas, and rope. The Department of Agriculture even released a short documentary, “Hemp for Victory,” in 1942, which promoted the plant as a useful crop for the war cause.
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.
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.
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.
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.
Hemp seeds can be used for a variety of everyday purposes and have been for years. The seeds of the Cannabis sativa plant are highly nutritious and can be found on the shelves of your local health food store. These seeds can be added to smoothies, salads, granola, and any other kitchen concoction you can scheme up in their processed form.

Although only the hemp plant yields true hemp, a number of other plant fibres are called “hemp.” These include Indian hemp (Apocynum cannabinum), Mauritius hemp (Furcraea foetida), and sunn hemp (Crotalaria juncea).
Hemp is grown in temperate zones as an annual cultivated from seed and can reach a height of up to 5 metres (16 feet). Crops grow best in sandy loam with good drainage and require average monthly rainfall of at least 65 mm (2.5 inches) throughout the growing season. Crops cultivated for fibre are densely sowed and produce plants averaging 2–3 metres (6–10 feet) tall with almost no branching. Plants grown for oilseed are planted farther apart and are shorter and many-branched. In fibre production, maximum yield and quality are obtained by harvesting soon after the plants reach maturity, indicated by the full blossoms and freely shedding pollen of the male plants. Although sometimes pulled up by hand, plants are more often cut off about 2.5 cm (1 inch) above the ground.
Hemp originated in Central Asia. Hemp cultivation for fibre was recorded in China as early as 2800 bce and was practiced in the Mediterranean countries of Europe early in the Christian era, spreading throughout the rest of Europe during the Middle Ages. It was planted in Chile in the 1500s and a century later in North America.
The hemp plant is a stout, aromatic, erect annual herb. The slender canelike stalks are hollow except at the tip and base. The leaves are compound with palmate shape, and the flowers are small and greenish yellow. Seed-producing flowers form elongate, spikelike clusters growing on the pistillate, or female, plants. Pollen-producing flowers form many-branched clusters on staminate, or male, plants.
