Hemp cbd oil harvest
Post Harvest processing is the immediate agricultural processing of wet and dried herbal material needed to prepare the hemp for industrial, food or medical use. Because the hemp industry is still young and growing, many new operators lack suitable equipment, infrastructure and systems to deliver a quality product. Industrial hemp processing for fibre, seed and oil is experiencing a renaissance as growers rediscover year old technology and innovate new equipment, products and processes to create a 21st century hemp industry. Whether processing hemp for industrial use or for CBD extraction , the same basic steps of post harvest handling are required. Processing standards and equipment for Industrial Hemp Processing and Medical Hemp Processing are compared and contrasted below. Processing practices and equipment vary significantly depending on the variety of hemp grown, the cultivation style, the available equipment and standard processes in the region.

Because of the newness of the industry, different farms and different regions often develop unique approaches and technology. A key point to understand when developing processing solutions for industrial vs medical hemp is that even though both plants are the same species Cannabis sativa they are grown and handled very differently.
A good analogy is Canola vs Broccoli — both are the same species but have been selected for hundreds of years to produce a particular crop. Canola rapeseed is an oilseed crop, whereas broccoli is a flower head crop from widely different varieties of the same plant. Likewise in hemp — some hemp varieties are cultivated for oil seed, some for food seed, some for fibre, and others for the resin component of the flowering heads.
Many varieties are dual-purpose or multi-purpose crops which allow harvest of seed, fibre, and then finally processing of the hemp biomass for CBD. When growing hemp for seed or fibre plants are grown close together which encourages long, straight stems and abundant seed production. Male plants are desirable to maximise seed formation and males are good for fibre as well. Plant spacing is often 10cm 4 inches spacing or even less, resulting in dense stands of tall, straight plants, looking almost like a crop of corn, sorghum or sugarcane.
High CBD Hemp grown for medical use is best grown using purpose-bred genetics following suitable husbandry practices. Unlike true industrial hemp, which has been selected for fibre and seed production, high CBD medical hemp should produce maximal flower and resin production. High CBD Hemp Cultivars exhibit the most desirable characteristics for the production of hemp derived-cannabinoid medicines.
The plants generally look, grow and smell more like a marijuana plant than an industrial hemp crop. Most of these strains are bred from higher CBD varieties of industrial hemp varieties with decent flower and resin production, which are then crossed high CBD medical cannabis varieties to boost potency and drug type phenotype characteristics. The ideal medical hemp cultivar will produce large crops of abundant flower heads with good high CBD resin production, while growing well outdoors in a range of weather events such as wind, hail, frost or drought.
The quality of these outdoor flower crops should be comparable to that of a food crop, medical marijuana or recreational cannabis — after all — this is going to be used to manufacture medicine. There is a significant flower for high quality flower which is used to produce products such as herbal teas and smoking products. Premium grade high CBD hemp flower may cost 5x to 10x more than most hemp flower which will only be used for extraction.
High CBD Hemp Genetics are beginning to be better understand now that cannabis is legally easier to study.
Key considerations include ensuring that the supplier of the hemp has the rights to use the genetics. Some strains have plant breeders rights and prohibit use of the seed or clones for production. If this is not in order the farmer may be using stolen genetics then the product may not be their to sell.
Ensuring that the CBD:THC ratio of the plant and other characteristics relevant to processing such as harvesting and processing requirements is important to plan for, and should be consistent within a cultivar. For medical end uses, especially for full spectrum CBD products, a known genetic source, cultivar and processing method is required to meet GMP consistency requirements. Industrial hemp is harvested by specially modified harvesting equipment such as combine harvesters.
In contrast, high CBD medical hemp is typically harvested by hand. Drying hemp post-harvest is the most important step as it determines the ultimate product quality. If hemp is dried quickly, cleanly and with minimal damage or loss of the product it maximises the quality of food, medicine or fibre products from the harvest.
In contrast, hemp that is harvested too wet, or dried too slowly, or with inadequate ventilation, or gets dirty or contaminated by fungi or bacteria during harvest and drying may become spoiled, unsaleable and totally unsuitable for food or medical processing. Farmers wanting to enter the hemp industry often fail to adequately plan and prepare their hemp drying facilities.
Hemp Drying equipment can help accelerate drying when large crops are planned. When producing hemp for fibre harvesting begins when plants are between early bloom and seed-set and is carried out carefully to ensure that stalks are not damaged during harvest. Harvesting was historically done by hand but new modified equipment allows hemp fibre harvesting by machine.
After harvesting, the different components of the hemp plant stem must be separated — particularly the valuable fibre and inner core, or bast. This is achieved using a machine called a decorticator which separates the fibre from the rest of the stem. To make this easier, the fibre is typically retted to soften and separate the fibre before decortication.
The retting process has a big impact on the quality and end uses of the fibre produced. Some modern decorticators can also work with freshly harvested material and use post processing to remove resins and gums from the fibre. Obviously for hemp for fibre to be used for CBD extraction, the flower heads must be removed prior to fibre processing. When growing hemp for seed production harvesting begins approximately six weeks after flowering or when the seeds have ripened.
Hemp seeds can be harvested with a combine harvester and many different groups are developing and testing new equipment to improve this process.
Hemp is an inherently challenging plant to work with as the resin is stick and fibre can jam machinery, often requiring manual cleaning during operation. Once seed has been removed the remaining plant material may be extracted or pelletised for further use. When processing seed crop or fibre crop hemp plants for CBD after seed separation, the remaining plant material especially the leaves and flower heads can be extracted directly, or more often, pelletised for extraction at a separate facility.
Note that while regulations dictate that CBD may only be extracted from stalk and seed — these components contain negligible seed. Almost all the CBD in the plant is in the flower heads, followed by a smaller amount in the leaves. Pelletised hemp biomass is a waste product from hemp fibre and seed production, and has many uses such as animal feed, bedding or an absorbant.
For example, in Canadian pelletised biomass was widely used for CBD extraction and isolation. This approach poses serious quality issues — pelletised biomass has rarely been grown or handled appropriately for the production of a food product. Such material may often be contaminated with soil, mold, fungi, bacteria, heavy metals, pesticides and other farm chemicals.
In contrast to fibre and seed hemp crops, high CBD hemp is grown as a female-only crop, with wide plant spacing foot spacing is common. Plants are typically individually irrigated and managed. While self-staking varieties are preferred, larger plants may require training, staking or supports as their flowers grow and mature, particularly if weather is challenging. Cultivation style and varietal selection appropriate to the environment are critical.
Plants are harvested when flower heads are fully mature and beginning to ripen and dry. These may be combined with or complement THC testing required by regulators. In many regions, most strains must be harvested before fully mature to prevent THC levels exceeding legally prescribed limits typically 0. Plants that exceed this level are termed hot and their detection can require destruction of the crop.
Specific guidelines on testing and harvest requirements are subject to local or state regulation and advice — typically via the State Department of Agriculture.
After harvest, high CBD hemp must be dried to prevent deterioration and ensure maximum preservation of the valuable CBD and terpene content. Drying typically occurs inside large ventilated barns or specialised drying chambers or equipment, such as seed or tobacco drying units. It is important that these drying facilities are of a suitable standard for production of a food or medical product.
For example floors should be clean and dry, and there should be no insect or animal infestation such as birds nesting overhead which could contaminate the drying product. Due to the rapid growth of the industry much of the industry is currently using existing or adapted facilities for drying.
In many cases these have previously been used to house animals such as horse stables which introduces potential contaminants. Hemp plants are typically hung upside down as whole plants or large branches before the large stems are removed from the plants for further processing.
At this time, depending on the preferred extraction methods, the material may be ground and extracted including small branches and leaves or may be trimmed to a greater or lesser extent. For example most large scale processors work with the entire plant material often of lower quality hemp. Other processors prefer to process trimmed buds separately to produce a premium oil or distillate product.
Other processors take a middle ground and prefer to process untrimmed buds including sugar leaves but no stem or fan leaves. Hemp for use in food or medicine manufacture should be stored in appropriate facilities that allow control of temperature, humidity, light and hygiene to ensure potency, purity, and cleanliness of the product and packaging can be ensured. Storage and distribution facilities should incorporate areas for quarantine, storage and release pending testing, buyer approval and shipping orders.
During loading, transit and distribution the product should be stored under comparable conditions to ensure the quality and integrity of the product is maintained. As the hemp industry matures and becomes better regulated, manufacturing and quality assurance standards from other industries help inform best practice. Food grade and other agricultural standards such as organic certification may also be relevant. We aim to develop a full suite of GxP systems for our supply chain over the coming 18 months as the hemp industry evolves.
After hemp has been harvested, dried and processed it is ready to send to a CBD processing facility to extract the CBD rich hemp oil from the flower or biomass material. Our network of hemp processing facilities offers toll processing services for licensed hemp farmers. Free shipping in February Dismiss. Industrial Hemp Cultivation Style When growing hemp for seed or fibre plants are grown close together which encourages long, straight stems and abundant seed production.
This requires resin rich, drug-type genetics — albeit low in THC. Hemp Harvesting Industrial Hemp Harvesting Industrial hemp is harvested by specially modified harvesting equipment such as combine harvesters.
Hemp Drying and Storage Drying hemp post-harvest is the most important step as it determines the ultimate product quality. Hemp Processing for Fibre Production When producing hemp for fibre harvesting begins when plants are between early bloom and seed-set and is carried out carefully to ensure that stalks are not damaged during harvest.
Retting may be carried out in several ways with varying time, cost and quality outcomes Field retting or dew retting uses environmental moisture to soften the fibre over several weeks. Water retting softens fibre by water immersion Chemical retting uses chemicals to accelerate fibre separation Green retting uses a mechanical process to separate the plant components The retting process has a big impact on the quality and end uses of the fibre produced.
To ensure maximum yields from hemp seed crops the mature flower heads must be handled carefully. Seeds should be mature and plant material dry at the time of harvesting Seeds should be carefully separated from flower heads and other plant material Harvested seeds must be handled carefully to prevent damage, including when transferring seed.
Use of conveyors and other low-impact transfer mechanisms are appropriate Machinery such as augers which could damage seed should be run at low speed to prevent damage. Each batch of seed should be sampled separately to ensure maturity, quality and moisture content are appropriate for storage.
Pelletised Hemp Biomass for Extraction When processing seed crop or fibre crop hemp plants for CBD after seed separation, the remaining plant material especially the leaves and flower heads can be extracted directly, or more often, pelletised for extraction at a separate facility. Each individual batch must be properly labelled and located to prevent mixing of batches.

There are some visual cues to indicate when a hemp CBD crop is nearing harvest time. Most notably, the trichomes, or tiny mushroom-like resin glands that coat hemp flowers, will change from crystal clear to a milky white color.
Hemp Biomass: A Step-by-Step Guide to Harvesting
Field production of industrial hemp is getting lot of attention in Canada and the U. Oil from the seed and fiber from the stem are the two most common uses, and now the possibility of extracting cannabinoids CBD from flowers appears very attractive. Here are a few basic facts before you jump into cultivation for CBD extraction. Selection of varieties for CBD This is one of the very important aspects growers must understand. In , my colleagues at the Alberta Innovates — Technology Futures facility in Vegreville and myself completed a one-year study screening four hemp varieties for CBD content and developing best management practices. We tested four varieties and selected X because of its smaller size. Male plants were removed and all female plants were grown to maturity. In the final analysis, the CBD contents ranged from 0. It was also observed that at a density of five plants per square meter, average CBD was higher. So, in order to select a variety, gather as much information as possible.
