One of the most important aspects of hemp seed is its high mineral content, including magnesium, which creates a very soothing and relaxing sensation throughout the body. Magnesium has various stimulating qualities on enzymes and hormones that induce sleep. According to a report published in the Journal of the American Geriatrics Society, Serotonin is released when magnesium is administered, and it travels to the brain, where it becomes converted to melatonin. Melatonin is a powerful sleep aid, and insomnia patients have often claimed that magnesium supplementation is the reason. A single serving of hemp seed contains nearly 50% of the daily recommended dose of magnesium, so grab a handful and get guaranteed beneficial and restorative sleep.
For profitable hemp farming, particularly deep, humus-rich, nutrient-rich soil with controlled water flow is preferable. Waterlogged acidic, compressed or extremely light (sandy) soils primarily affect the early development of plants. Steep and high altitudes of more than 400 m above sea level are best avoided. Hemp is relatively insensitive to cold temperatures and can withstand frost down to −5 °C. Seeds can germinate down to 1–3 °C. Hemp needs a lot of heat, so earlier varieties come to maturation. The water requirement is 300–500 l/kg dry matter. This is around 1/14th that of cotton, which takes between 7,000 and 29,000 l/kg, according to WWF. Roots can grow up to 3 feet into the soil and use water from deeper soil layers.
Hemp plants grow brown popcorn kernel-sized hard seeds. Inside these hard seeds lie soft, white or light green inner kernels that are packed with essential amino acids, protein, and omega-3 fatty acids. You can't really derive a lot of nutritional value from the unhulled seeds, so when you see a bag at the store labeled "hemp seeds," what you're actually buying is those soft inner kernels, also known as hemp hearts. Hemp hearts can be pressed to make hemp seed oil, leaving behind a byproduct that can be turned into hemp protein powder. You can find all of these hemp products at health food stores, or a well-stocked grocery store like Whole Foods. cbd oil
