Cannabis sativa hemp
With interest in CBD cannabidiol rising and the Farm Bill legalizing hemp federally, there are many questioning concerning the difference between hemp and marijuana. Generally the difference between hemp and marijuana is in the concentration of THC tetrahydrocannabinol , with hemp generally considered so low in concentration so as to be non-psychoactive. Hemp is still cannabis sativa, same as some of the most popular strains of marijuana. Hemp is typically grown to maximize the overall size of the plant as quickly as possible, usually achieved by growing outdoors. A lot of marijuana, though not all, is grown indoors, so as to control many variables such as light cycles and soil nutrients. Hemp has been cultivated for industrial applications for centuries.
Hemp vs Marijuana: Is There a Difference?
Coarse, bushy herb up to 4m tall. Leaves grey-green, up to 12cm long, palmate with lanceolate leaflets, margin serrated. Individual plants either have male or female flowers dioecious.
Flowers small, green and clustered. Fruits small, dry and thin-walled achene , contain only one seed. Pollinated by wind. For centuries hemp has provided raw materials for paper, textiles, rope for ships, medicine, oil and much more. It is one of the most useful multi-purpose crops of the temperate world quoted as having over 25, end products.
For example, the seed can be used as a food protein and the outer stem provides fibre for ropes and canvas for tents. It is illegal in most countries because the leaves of the high-THC types can be dried and smoked to provide a mild narcotic. In order to grow hemp at Eden we needed an industrial licence and a physical barrier, so the barrier became the artistic installation: the Hemp Fence designed by George Fairhurst. It is also a symbolic barrier: visitors are invited to stick their neck out to see what is on the other side.
The hemp at Eden is grown under an industrial licence. Video Hemp growing at Eden. Facts Hemp grows fast, is very adaptable to soil and climatic conditions and is undemanding on resources such as artificial fertilisers and pesticides. It provides a good break crop for the farmer, giving the land a rest from other crops and helping to prevent disease.
It produces a substance that became socially controversial in the early part of the 20th century: tetrahydrocannabinol THC , which as well as having many medicinal attributes has been used as a recreational drug. In recent years breeding and selection has resulted in cultivars low in THC, and hemp is once again being considered by governments as a useful crop.
One of the oldest relics of human industry is a bit of hemp fabric dating back to approximately 8, BC. Hemp is six times as strong as cotton, much more resistant to weathering and wear, and more lustrous and absorbent. It is also much more environmentally friendly to grow. Hemp growing became commonplace in Britain under the Romans and continued into the mids. He was interested in it for making rope — very important, especially to ships in those days.
Palmate : when all lobes originate from a central point lobes are incomplete divisions in the leaves. Scabrous : rough to the touch.
Cannabis sativa seeds are chiefly used to make hempseed oil which can be used for cooking, lamps, lacquers, or paints. They can also be used as caged-bird. Hemp, or industrial hemp, is a variety of the Cannabis sativa plant species that is grown specifically for the industrial uses of its derived products. It is one of the.

Marijuana vs. hemp: What’s the difference?
Hemp , Cannabis sativa , also called industrial hemp , plant of the family Cannabaceae cultivated for its fibre bast fibre or its edible seeds. Hemp is sometimes confused with the cannabis plants that serve as sources of the drug marijuana and the drug preparation hashish. Although all three products—hemp, marijuana, and hashish—contain tetrahydrocannabinol THC , a compound that produces psychoactive effects in humans, the variety of cannabis cultivated for hemp has only small amounts of THC relative to that grown for the production of marijuana or hashish. The hemp plant is a stout, aromatic, erect annual herb. The slender canelike stalks are hollow except at the tip and base.
Hemp vs Marijuana: Breaking Down the Difference
Conclusion: Careful consideration of the extraction method is very important for the measurement of cannabinoids in hemp seeds. Cannabis spp. Hemp is a variety of the Cannabis sativa plant species that is grown specifically for the industrial uses of its derived products. In most nutritional food stores and grocery stores, hemp seeds are a staple nowadays, in countries where it is legal. Hemp seeds produce negligible, if any, quantities of THC endogenously. We were interested in investigating various chemical procedures that one could employ to extract natural products, effect of solvents in these extraction methods, and ultimately the estimation of various compounds in the extract. Three brands brand 1, 2 and 3 of hemp seeds were purchased from local supermarkets in Toronto, Canada, and were used as such in the laboratory experiments. All experiments, including extractions and analyses, were conducted under the appropriate Controlled Drugs Substances Dealer License granted to University Health Network. Four extraction methods were used to extract resins from three brands of food-grade hemp seeds. Each brand of hemp seeds was subjected to each extraction procedure thrice to assess any variability that might arise from the extraction procedure itself.
Cannabis sativa is an annual herbaceous flowering plant indigenous to eastern Asia but now of cosmopolitan distribution due to widespread cultivation.
Its leaves are made up of long, narrow blades. In general, the foliage of a Sativa plant is somewhat sparser than that of the other varieties. This is due to the tropical origin of Sativa strains.

When trying to wrap your head around the differences between hemp and cannabis, it is important to begin with this simple concept: Both hemp and cannabis ultimately come from the same plant… just different parts. Whether you call something hemp or cannabis will depend on a variety of factors which we will explore in this article. However, despite the fact that the terms hemp and cannabis are often used interchangeably, they do have separate connotations. Unfortunately, prohibition has spurred a lack of education surrounding the cannabis plant. This has led to countless rumors about what makes hemp different from cannabis. So, how are these terms supposed to be used? Further, there are countless varieties that fall into further classifications within the species Cannabis Sativa. However, depending on how the plant is grown and utilized will determine which term is correct. For instance, the term cannabis or marijuana is used when describing a Cannabis Sativa plant that is bred for its potent, resinous glands known as trichomes. These trichomes contain high amounts of tetrahydrocannabinol THC , the cannabinoid most known for its psychoactive properties. Hemp , on the other hand, is used to describe a Cannabis Sativa plant that contains only trace amounts of THC. Hemp is a high-growing plant, typically bred for industrial uses such as oils and topical ointments, as well as fiber for clothing, construction, and much more. Only products made from industrial hemp less than 0. This single factor 0.
Hemp , or industrial hemp , is a variety of the Cannabis sativa plant species that is grown specifically for the industrial uses of its derived products. Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol THC , they are distinct strains with unique phytochemical compositions and uses. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content. In those languages "hemp" can refer to either industrial fiber hemp or narcotic cannabis strains. Hemp is used to make a variety of commercial and industrial products, including rope, textiles, clothing, shoes, food, paper, bioplastics, insulation, and biofuel. The inner two fibers of the plant are woodier and typically have industrial applications, such as mulch, animal bedding, and litter. When oxidized often erroneously referred to as "drying" , hemp oil from the seeds becomes solid and can be used in the manufacture of oil-based paints, in creams as a moisturizing agent, for cooking, and in plastics. Hemp seeds have been used in bird feed mix as well.
