Let’s go back to the 10,000 kg of CBD isolate per month PO. This equals 120,000 kg of isolate a year. Current estimates suggest there are around 26,000 acres dedicated to hemp production in the US . Therefore, the entire production of CBD isolate in the US, assuming every single acre is dedicated to CBD-rich cultivars, could yield around 1.4 million kg.
It is difficult to believe how much disinformation, malarkey and plain old Androgenic Bovine Manure (aka Bullshit) we still have around simple facts and figures when it comes to parametrize outdoor cultivation of hemp and potential production of CBD oils and isolates.
Let’s start by trying to establish how many hemp plants (or how much biomass) can be cultivated per surface area. Canadian provinces like Alberta and Manitoba have very compressive programmes for cultivation of industrial hemp. The websites of both programmes offer very detailed numbers of expected yields depending of the crop modality (fiber, seed or mixed) [2, 3]). Unfortunately, none of these numbers really apply to current practices in outdoor hemp operations specifically seeded for production of CBD-rich cultivars.
I am not a farmer. I have never been in a hemp field but I am a plant physiologist and I like to work around Fermi Problems  for fun. I don’t want to prove or disprove any particular figure or rule of thumb, I just want to share with the network a simple exercise hoping to start a conversation. I welcome all comments and corrections from anyone with first hand experience, expertise or reliable sources.
The question I would like to answer is: Could a “10,000 kg of CBD isolate per month purchase order” be fulfilled using only outdoor hemp grown in the USA?
I was recently on the East Coast visiting a couple of potential sites for my new company. During my visit I had the opportunity to talk with several investors and entrepreneurs looking to move away from the cultivation space into offering post-harvest processes under the “As-A-Service” model.
Since plants growing in legal outdoor operations are treated as small trees in an orchard (i.e., they are properly irrigated and fertilized), a plant density of 1 plant per m2 could be used as a reference (this density has been reported for well-cared Cannabis plants growing outdoors [4,5]. At this density well-cared plants can develop large, multi-branched canopies. Using this density, we should expect 4,046 plants per acre. Well-cared Cannabis plants grown outdoors at this density regularly yield 1 to 2 pounds (0.5 – 1kg) of fresh bud per plant [4, 5]. These numbers bring us to a total yield of 2,023 to 4,046 kg of bud per acre. For simplicity let’s settled for 3,000 kg per acre .
Here we dive into major factors like product type, moisture content, quality and volume with an extensive guide to today’s hemp and CBD market price trends.
Crude hemp oil is extracted from the hemp plant through one of several methods. The most common methods are pressurized CO2 or solvent extraction using ethanol or a hydrocarbon. Crude hemp oil contains all of the cannabinoids (including THC), terpenes and flavonoids found naturally in the plant. It’s often further purified ( winterized ) to remove organic plant compounds such as lipids, waxes and chlorophyll, which increases the product’s overall potency. But can break down some more fragile compounds like terpenes and flavonoids.
Price Trends by Hemp Product
Croptober did not affect the price of CBD flower as dramatically as it did biomass. In June 2019, CBD flower sold for about $349 per pound wholesale. The price dropped to an average of $319 per pound in October followed by sharper decline as of the latest report in December. CBD flower is now selling at $226 per pound, representing a 35% dip in 6 months.
Aside from CBD and THC, lesser known cannabinoids like CBG (will link to the blog) or CBN are making the biggest difference in price. According to Hemp Benchmarks the price of CBG biomass varies, but generally sells for around $22.42 per % CBG per pound (wholesale), equating to roughly $175 to $325/pound overall.
Dried CBD flower refers to the bud and trichome portions of the hemp plant, which are removed from the stalks and stems. Dried flower is smokeable and sold alone or in pre-rolled joints. Dried CBD flower commands a higher price point than CBD biomass because it has been cut, trimmed and is ready to sell.
CBD Tincture Dosage Calculator. This is primarily why there is an optimal window for mill size, and we recommend somewhere approximately around 1/4” particle sizes. The colder your solvent, the slower it will be at dissolving your target cannabinoids. THC Oil Yield Calculator based on Greenhouse Flowering Area. is an optimal window for mill size, and we recommend somewhere approximately around 1/4” particle sizes. Yes, it is indeed. if one batch of biomass has a potency of 10%, you can easily get 80-90% yields (% of cannabinoids extracted compared to total cannabinoids in biomass). One other very important factor the mill of your biomass is going to directly affect is the amount of biomass you can fit in each CUP bag, which determines how many lbs. One of which we already mentioned; how fine you mill your biomass, is going to directly affect how many pounds per CUP-30 bag you can fit. The distillate has been enriched in the lower-boiling component. For each ethanol extraction you perform it is inevitable that you will lose some ethanol and therefore a bit of cannabinoid lost in the solution. the distillate was greater than 50% cyclohexane and less than 50% toluene. he mill size of your biomass as discussed above, are the two most important factors that are going to determine the amount of time required for a, The colder your solvent, the slower it will be at dissolving your target cannabinoids. Address This is the essence of distillation – starting with a mixture of liquids having different BPs, going through the process of distillation, and ending up with if another batch of biomass has a potency of only 4%, you will probably never attain yields higher than 75%. half of the base of each peak would yield relatively accurate areas for each peak. But back to our calculation problem. The losses due to transfers are significant on this scale. The time in which it takes you to perform an entire extraction cycle is going to directly determine how many extractions you can perform in any given work shift. % yield calculation Example 14.2a (6) (reaction of impure limestone with hydrochloric acid) 0.400g of an impure sample limestone produced 92.5 cm 3 of carbon dioxide at 25 o C and 101kPa laboratory pressure. This calculator will estimate the weight of output of marijuana biomass, THC oil, THC distillate for a given input of greenhouse flowering area. The mill size of your biomass as discussed above, along with your solvent’s temperature, are the two most important factors that are going to determine the amount of time required for an efficient extraction to take place.
Keep in mind that catalysts are usually used in 1-10 mol% quantities to speed up reactions and not in stoichiometric quantities. Creating the bridge between cannabis and hemp producers/processors, and retailers. The yield calculation that you perform for most synthetic procedures is based on the comparision of moles of product isolated and moles of product that you can theoretically obtain based on the the limiting reagent.
