Cannabidiol, also known as CBD (mabaosu DM CBD in China), is a popular compound derived from cannabis plant and has a variety of potential health benefits. CBD can be derived from cannabis plants. However, CBD extracted from cannabis plants is known to have high levels of tetrahydrocannabinol, which can produce psychoactivity and bring excitement to users. On the other hand, the content of tetrahydrocannabinol in cannabis derived CBD is less than 0.3%.
Before attempting to start cannabis cultivation, it is important to understand the requirements of local policies. The first rule requires you to grow only marijuana with a concentration of less than 0.3% THC. You should also contact your county, city and local district authorities to find out whether you need to comply with any other laws, regulations and means of transportation. This is important, especially if you grow marijuana for industrial purposes. You will need to register as an industrial marijuana grower and obtain a license.
Unless you want to grow marijuana for its fiber, you don't need any special farm equipment. Marijuana for CBD production can be planted with ordinary agricultural machinery. In addition to alpine areas and extreme desert climates, cannabis plants can thrive in most environments. Marijuana grows best in warm weather. In addition to being rich in organic matter, it should also be well drained.
Before planting cannabis seeds, it is recommended that the soil be tested by agricultural extension personnel with cannabis planting experience. This will ensure that the content of phosphate rock, potassium sulfate and elemental sulfur is most suitable for plant growth. Soil tests conducted in early spring or late autumn have been shown to provide more accurate and reliable readings.
Cannabis seeds should be planted directly into the soil, rather than potting them before planting. When the soil temperature is about 50 degrees Fahrenheit (usually between May and June), sowing seeds can help them germinate and emerge quickly. This will allow plants to grow tall and increase yield potential. Seeds should be sown relatively close, ideally within four inches. However, it will depend on the size of your marijuana farm and the crop yield required.
The sowing depth of seeds shall be within ½ reach ¾ Between inches. If seeds are sown mechanically, conventional sowing equipment (such as corn planter or grain planter) should be able to do this. After sowing, the soil shall be rolled up and packed. For the first six weeks after planting, you will need to fully irrigate marijuana seeds. Although cannabis plants are usually drought resistant, germinating plants are fragile and sensitive to dryness.
Marijuana is usually a plant resistant to diseases and pests. The plant can grow any surrounding weeds and can grow organically, so you don't need to invest a lot in supplementary nutrition. However, if you have to use any pesticides on marijuana farms, it is recommended that you first check the regulations on pesticide use in your jurisdiction. Although the federal government regulates the use of pesticides in agriculture, your state may have other stricter regulations
Cannabis plants can usually be harvested within 120 days. If you sow in May or June, you can prepare to harvest plants around September or October. The head of the cannabis plant is considered to be fully mature 90 to 100 days after planting. If you wait too long to harvest crops, their quality will decline and your yield will be reduced. The most common signs of maturity and preparation for harvest are the redness of pistils, the widening of stems, the redness of brown resin on buds, and the yellowing and death of plant leaves.
After harvest, it is recommended to test the CBD and thc levels of plants to ensure that the THC level does not exceed the legal limit. Before storage, the foreign matters in the harvest shall be removed and waiting for treatment.
Extracting CBD oil from marijuana factory
After harvesting cannabis plants, they are usually processed to extract CBD oil (called mabaosu DM CBD in China). There are four ways to extract CBD oil from cannabis plants:
Carbon dioxide (CO2) extraction
Carbon dioxide extraction is the most effective and complex method to extract CBD oil from cannabis plant. It ensures high-quality CBD and is safer. Most industrial manufacturers of CBD oil products use this method. In this extraction method, pressurized carbon dioxide is used as a solvent and to extract CBD oil from plants.
Some advantages of this extraction method include:
• you can adjust it to obtain different molecular weights.
• there is no residual solvent in the generated CBD oil.
• this method is most appropriate if you need to store terpenes in CBD or carry out temperature sensitive extraction.
• it's easy to automate this process.
• in addition to carbon dioxide monitors and safety signs, you also need to bear the lowest safety cost.
The equipment required for this extraction is very expensive. If you are using budget equipment, you will have to endure slow extraction speed. The manual operating system used for this extraction method is also very complex and difficult to learn.
Different from CO2 extraction method, extracting CBD oil from cannabis plant with ethanol is very easy and cheap. Cannabis plants are usually soaked in ethanol solvents. This will dissolve CBD and other compounds in plants. The ethanol is then evaporated to leave CBD oil. The disadvantage of this method is that other materials, such as chlorophyll, will also be extracted. CBD oil extracted in this way is known to have grass flavor and bitter taste. Heating also destroys cannabinoid and activates THC. In addition, trace solvents may remain in the extract. You will need a secondary treatment to remove unwanted substances from CBD oil.
In this method, light hydrocarbon solvents with low boiling points are used, such as acetone, isopropanol, hexane, propane, pentane and butane. CBD extracted in this way has a high titer level and is very suitable for making smearable CBD products, such as CBD chips, chips and honeycomb. The extraction speed is also very fast.
However, when this method is used, a large amount of residues will remain in CBD oil. The terpene concentration in CBD oil will also be greatly reduced. In addition, this method is very dangerous.
For small-scale production of CBD oil, oil extraction is the cheapest and simplest method. In this method, the dried cannabis plant is first heated to a certain temperature to activate cannabinoid. After completion, the vegetable material is added to the oil and then heated to extract CBD. Coconut oil or olive oil is usually used in this process. This extraction method is more common in boutique companies and manufacturers of self-made CBD oil.
After the extraction of CBD oil is completed, it can be further distilled to remove any undesirable components, such as wax, other cannabinoids and lipids. This can be done through a process called antifreeze. If a pure CBD isolate is to be obtained, another process called short-range distillation usually needs to be completed.
According to the extraction method and level, different types of CBD oil can be produced from cannabis plants. These include:
• full spectrum CBD oil, which contains all natural compounds found in cannabis plants, such as amino acids, terpenes and other cannabinoids.
• broad spectrum CBD oil, which contains all compounds other than THC. THC is extracted from a broad spectrum by a method called liquid chromatography.
• CBD isolate, which only contains pure CBD (called mabaosu DM CBD in China) and does not contain other compounds.
