What is CBG?

CBG is a phytocannabinoid found in cannabis plants, generally at very low percentages compared to other cannabinoids. Also for this reason, we have numerous varieties of cbg seeds in our cannabis seed catalog. Thanks to these light cannabis genetics it is possible to obtain extremely high levels of cannabigerol present in the inflorescences.

Effects of the CBG

Like other cannabinoids, CBG has numerous health benefits, in fact it can be used as an anti-inflammatory, antidepressant, as well as being mentally stimulating and energizing. Obviously, this will happen if the cannabigerol is taken alone, in fact with the combination of other cannabinoids the effect will not be only this. In addition to this, thanks to its euphoric effect it can be used as an anxiolytic. Numerous scientific researches have also shown that it is useful for combating inflammatory bowel diseases, OCD and is very useful with the aim of avoiding cellular neurodegeneration. Unlike thc, it is not a psychoactive cannabinoid, also thanks to this it is a totally legal substance in Europe.

What are high CBG cannabis strains?

In our online cannabis seed store we have numerous strains with excellent levels of cannabigerol. The genetics with the highest cbg percentages is Sticky Force CBG, which is a legal marijuana strain with 15% cbg content, and totally zero thc concentrations (0.0%)! Another particularly popular variety in our catalog is the Swiss CBG X Gelato CBG, which also has totally zero thc and cbd values of 0%, but has the special characteristic of generating CBGA values of 5.5%. CBGA, also called cannabigerolic acid, has a fundamental role in the creation of cannabinoids in marijuana and hemp plants; in fact, without it cannabinoids such as thc, cbd, cbg would not exist.

That’s when the time is right to harvest the plants

It is very difficult, especially for novice growers, to know for sure when is the right time to harvest plants for the purpose of achieving high CBG content. In particular, every grower has their own technique to find out, so our team of Grace Genetics experts will recommend two simple and practical methods:

White pistils of cannabis plant
  • Red pistils: This is a basic but extremely safe technique, in fact checking that at least 50% (or more) of the pistils have reached a color very similar to red, it will be essential to harvest the plants ensuring high levels of CBG. Those wishing to obtain even higher concentrations, however, will have to wait until at least 70-80% of the pistils have turned red;
  • Changing the color of the resin: This is a bit more complicated method, because we will need a microscope. When the color of the resin turns from transparent to milky white it will be the ideal time to harvest our cbg seedlings. We recommend not cutting and harvesting before this time.

We also recommend not harvesting plants too late, as each cannabinoid will deteriorate, which means that it will lose potency and as a result it will no longer be as special as it used to be.
