THC, CBD, and CBN. What does every grower need to know?

how to grow marijuana

THC (Tetrahydrocannabinol), CBD (Cannabidiol), and CBN (Cannabinol) are best studied, and these compounds are present in cannabis in the largest quantities. The appropriate balance of cannabinoids is different for each individual since the same percentage of THC is felt differently depending on the presence of other cannabinoids. For example, inflorescences with high THC and low CBD and other cannabinoids are more likely to cause anxiety, disorientation, and memory problems. In order to be more mobile and adequate, marijuana should contain some amount of CBD and CBN.

What does it really mean when you see in cannabis 18.2% THC, 0.1% CBN, and 0.5% CBD?

First of all, it does not mean that we can weigh cannabis, count 18.2% of this weight, and say that there are 182 mg of THC in a gram. These are percentages and by no means the weight of the cannabinoids! These numbers are intended to explain that THC takes up 18.2%, another 0.1% for cannabinol, and half a percent for CBD of all the cannabinoids in such a plant. When using marijuana, this manifests itself in the fact that the buds of different plants with the same percentage of THC may be different in strength because the actual number of cannabinoids in them may be different, even if their ratio is the same.

What’s the ratio of these cannabinoids supposed to be?

Every grower can only know the answer to this question individually by analyzing its inflorescences to the level of cannabinoids, comparing the feelings of cannabis with different ratios of THC, CBD, and CBN. You can find out what kind of cannabis your body would like to get. Sorts with high THC have their advantages but from the point of view of most smokers, the effects of tetrahydrocannabinol are more easily experienced if softened by the calming effects of CBD and CBN.


THC is the main psychoactive component of marijuana trusses. THC acts like anandamide in the brain and is naturally present in our body as part of the endocannabinoid system.

  • Noticed the beneficial effect of THC on human health. Improved metabolism, elimination of some neuroses, oncological effect;
  • THC contributes to the fine-tuning of a person’s mental state which can manifest itself as a sudden release of creative potential or the emerging desire of a noncommunicable person to communicate with neighbors; often the effect of THC is associated with a sense of joy and well-being;
  • The too high concentration of THC (especially if there are few other cannabinoids) can cause anxiety, a feeling of weakness, disorientation in time or space;
  • THC eliminates some types of pain syndromes;
  • The use of THC prevents the development of degenerative processes in the brain and removes inflammation of brain tissue associated with Alzheimer’s syndrome, this property of THC is called neuroprotective;
  • It usually has a relaxing effect;
  • Temporarily changes perception and thinking.

How can we get a high level of THC?

  • First of all, choose a variety with high THC. This is the main thing you can do;
  • The bigger the resin, the bigger THC you have. It requires perfect care and as much light as possible, as well as adequate temperature and sufficient ventilation to increase resin production;
  • Cut your harvest when most of the trichomes are milky white (not transparent) and some are red;
  • Train your hemp – all techniques that increase harvest also contribute to the production of cannabinoids.

Recall that huge THC does not always guarantee that you will want to repeat the experience with this hemp because the entire bouquet of cannabinoids is responsible for your condition.


Cannabis plant
  • The CBN is also psychoactive but much less than THC;
  • The presence of a CBN in the plant softens the THC and contributes to calmer trips without some helplessness that threatens those who have had too much with THC;
  • Promotes a relaxing hemp effect;
  • Reduces the frequency of night awakenings;
  • Excess CBN in the grass can make a smoker nap.

How to get more CBN?

  • The longer you don’t cut the plants, the higher CBN you have;
  • The redder hairs there are, the more CBN, but to the detriment of the other cannabinoids, so it is not advisable to hold the cannabis too much.


cannabis growth
  • CBD has no psychoactive properties and is not felt after cannabis use;
  • CBD has many opportunities for therapeutic use. It has neuroprotective, anti-inflammatory, antispasmodic, and anti-epileptic effects;
  • CBD reduces your experience of THC. Higher levels of CBD make the grass less psychoactive. This can be a great advantage for some patients interested in treatment on a permanent basis without cannabinoid dipsomania. CBD eliminates THC effects such as difficulty in thinking and orientation;
  • CBD causes relief in such diagnoses as multiple sclerosis, migraine, and epilepsy;
  • Noticed antipsychotic effect in schizophrenia;
  • Slows down the multiplication of cancerous cells.

How to increase CBD?

  • As in the case of THC, first of all, you need to choose a variety with a high CBD;
  • The CBD content of auto flowers developed with ruderalis genetics is usually slightly higher;
  • In recent years, it has been possible to select marijuana varieties on the market which have a lot of both CBD and THC.

Except for the choice of the sort, there is little you can do to increase the CBD. Some explorations of technical cannabis in the open-air suggest CBD increases in the case of particularly warm ground and air, and rare rain, but these methods will not necessarily work indoor with cultural cannabis. The best results are achieved by cloning plants with high CBD.

Dry – the last thing you can do for cannabinoids

Firstly, if you dry quickly some substances will be destroyed and part of the THC will not have time to move into its psychoactive form.

Secondly, the process of drying makes the inflorescences tastier and more combustible, reduces irritation to the throat when smoking, and increases psychoactivity. The drying of the inflorescences in a jar lasts 2-4 weeks. Longer drying of inflorescence leads to the fact that part of THC turns into CBN and your stuff becomes less strong but more sedated. However, many weed lovers think that a CBN improves the effects of THC and its presence is necessary.
