Other varieties and planting strategies are used to grow hemp for hemp seed oil. Then, within the hemp grain sector, seeds can be processed for flour, hemp food supplements, and then onwards to a thousand uses within the food sector. Then there is the hemp hurd and bast fibre which has a multitude of uses. A number of separate possible revenue streams from the same plant; however in this article we focus mainly hemp grown for CBD oil extraction.
High value industrial hemp crops for CBD oil extraction from the leaf / flower / bud grown mainly as tree like hemp plants. Harvesting this form of industrial hemp in a whole crop method with forage choppers produces a type of wet woody biomass with leaf and flower in the mix.
Hemp Harvest Timing
Of course there are many other factors to consider when selecting the correct varieties to grow; such as biomass-to-seed index and CBD oil levels depending on the purpose of the crop. It can be challenging to balance this all with the management of the regulatory processes relating to low % THC industrial hemp while optimising higher CBD oil contents. Post-harvest management of the wet biomass and correct equipment selection for hemp drying is key to avoiding significant losses of the crop for CBD oil extraction.
The other main types of industrial hemp crop are tall single stem hemp plants close-planted for seed / dual purpose uses. This type can have CBD oil extraction from the leaves, buds and flowers, but also can have hemp seed oil extracted from the seeds. It is not a simple process to optimise both the CBD oil yield and hemp seed yield.
Early varieties have a key benefit in the harvesting and drying process of field-scale industrial hemp for CBD oil operations. The early autumn weather is often more reliable and therefore the ambient day (and night) temperatures are higher with lower relative humidity, enabling large increases in dryer output while reducing dryer fuel requirements.
Hemp is a highly versatile crop that can be farmed for a variety of different products. You can farm hemp for fiber, grain, CBD oil, CBG oil, smokable flower, and more. Certain hemp products are more profitable than others. For instance, CBD oil can be very profitable and, on the premium end, can sell for more than $1000 per kilogram.
Is it profitable to grow hemp? If you are looking to cultivate cannabidiol (CBD) oil or cannabigerol (CBG) oil, the answer can be a resounding yes if you follow best practices. Here are 10 invaluable tips on how to grow hemp for profit.
2. Choose a Profitable Product
Hemp, like all crops, has its unique growing challenges. One of those challenges is that hemp farming in the U.S. was illegal for decades, meaning that accurate knowledge and experience are in short supply.
For example, even if your main interest lies in producing CBD extract, you may want to set aside a few acres for a seed like Matterhorn CBG to try out CBG extract. If CBG becomes as hot of a commodity as CBD, then you could be one of the first farmers to market. Plus, the reliably low THC levels, even when left in the field, ensure you have a compliant harvest.
Before you spend a lot of money on your first purchase of hemp seeds, consider what strain will be the most profitable for you. Most hemp seed companies provide a variety of hemp seed strains. Each strain offers unique benefits. Some are designed for specific growing conditions, others for particular climates, and some are designed to grow fast or grow in a particular season. Many strains also produce interesting flavors. Some drip in resin for extraction and some are bred for the aromatic flowers to be smoked and appreciated by CBD consumers.
Once you’ve harvested the hemp, cleanse all foreign material from the grain and prepare it for storage until the time you’re ready to process it. Make sure it is properly aerated immediately to avoid spoiling. Dry hemp grain to approximately 9% moisture. Best for drying hemp is a belt conveyor, though you can use an auger as well, as long as you run it slow and full. This will help keep seeds from cracking.
Sow seeds relatively closely together, as close as four inches, depending on the size of your growing space and the yield of your desired crop. Plant seeds at a depth of around 1/2 to 3/4 inch. Aim for seeding in 15-inch to 30-inch rows at a rate of 25 to 35 pounds per acre. If you sow seeds mechanically, you can use conventional seeding equipment to plant hemp seeds with no other special equipment required. Either a grain drill or a corn planter will suffice. Once the seeds are planted, it is recommended to roll and pack the soil.
Even though hemp has less than 0.3 percent of psychoactive THC, cultivating it and extracting CBD from it was strictly prohibited by the Federal Government. To grow hemp legally in a US state, you must still contact city, county and local zoning agencies and officials regarding any regulations, codes and conveyances with which you may need to comply. Also, you must make sure that your hemp has less than 0.3 percent of THC, as this is a basic prerequisite for staying compliant.
Growing Hemp for Profit
The growing cycle for hemp is approximately 108 to 120 days, during which these growing conditions should remain relatively stable and consistent.
Hemp farming is one of the most lucrative industrial and textile crops you can start on the US right now. According to the 2018 Farm Bill , CBD and hemp are completely legal to grow and sell in the United States, creating a billion dollar market that is expected to grow exponentially. Whether you plan growing industrial hemp for its grain, fiber production, seeds or CBD oils, the process of growing it, from seed to harvest, is the same. If you want to start a hemp farm, read our handy guide below.
As with seeding machinery, standard combines are adequate harvesting equipment and no other special machinery is required. If desired, you could use a rotary combine with a draper header instead. To minimize fiber wrapping, harvest only when grain moisture is between 12 and 18 percent. Set your combine to settings similar to those for harvesting canola or wheat. To minimize how much fiber enters the combine, cut plants immediately below the head of the grain. Growing conventional (inorganic) hemp, you can expect to yield approximately 1,000 pounds per acre. Yields for organically grown hemp are closer to 500 pounds per acre.
To harvest hemp fiber, wait one or two days minimum after harvesting the grain and ideally until the following spring. Bale hemp fiber at no greater than 15% moisture in big square bales. Expect to yield approximately one to three tons of hemp fiber per acre.
