In the early 1990s, industrial hemp agriculture in North America began with the Hemp Awareness Committee at the University of Manitoba. The Committee worked with the provincial government to get research and development assistance, and was able to obtain test plot permits from the Canadian government. Their efforts led to the legalization of industrial hemp (hemp with only minute amounts of tetrahydrocannabinol) in Canada and the first harvest in 1998.[85][86]
The recommended minimum daily intake of Shelled Hemp Seeds is a 42 grams (4 heaping tablespoons) serving. Larger individuals or those suffering with chronic health conditions such as arthritis, high blood pressure, high cholesterol, cardio vascular disease, acne, eczema, psoriasis, diabetes, circulation problems, intestinal problems, constipation, obesity or prostate problems (to name a few) may want to consider taking 55 grams (5 to 6 heaping tablespoons) a day.
The seeds are sown with grain drills or other conventional seeding equipment to a depth of 1.27 to 2.54 cm. Greater seeding depths result in increased weed competition. Nitrogen should not be placed with the seed, but phosphate may be tolerated. The soil should have available 89 to 135 kg/ha of nitrogen, 46 kg/ha phosphorus, 67 kg/ha potassium, and 17 kg/ha sulfur. Organic fertilizers such as manure are one of the best methods of weed control.[60]
The first example of the use of hempcrete was in 1986 in France with the renovation of the Maison de la Turquie in Nogent-sur-Seine by the innovator Charles Rasetti.[30] In the UK hemp lime was first used in 2000 for the construction of two test dwellings in Haverhill.[31] Designed by Modece Architects,[32] who pioneered hemp's use in UK construction, the hemp houses were monitored in comparison with other standard dwellings by BRE. Completed in 2009, the Renewable House is one of the most technologically advanced made from hemp-based materials.[33] The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.[34]
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
