CBD HEMP: THE CULTIVATION
The cannabinoid CBD or cannabidiol is a molecule naturally produced by the Cannabis plant that can counteract the psychoactive effects of THC and that generates relaxing and non-psychotropic effects.
Isolated for the first time by organic chemist Roger Adams in 1940, CBD is a non-psychoactive molecule, but was best studied only from the 21st century along with other cannabinoids, in addition to THC.
Of the more than 500 natural compounds present in Cannabis, at least 85 are believed to be cannabinoids. It’s shocking that in 2020 we just scratched the surface of cannabinoid research. However, with the best data available at the moment, we are able to share all the information obtained so far about CBD.
The stages of Cannabis cultivation
Five phases make up the cycle of production of Cannabis, but the overall duration can vary in low to the cultivated species. However, on average a Cannabis cultivation takes about 3 to 6 months (from germination to harvest). This argument is not valid, however, for the self-flourishing species, which reach the blooming within few weeks, independently from the hours of exposure to light (we are talking about a period of time ranging from 60 to 80 days).
During the first week after the sowing, we find immediately the first phase of the cycle, that is the germination which consists in the emergence of the sprout from the planted seed. This phase can be easily facilitated: just wrap the seed in a wet napkin or cotton wool, so that it can be represented its ideal habitat before moving in a pot.
After the germination part, there is planting which would be the stage in which the bud continues its development, taking the form it will maintain during growth. To make this happen, the bud will need a long exposure to light (18-24 hours, it is called "light cycle"), a lot of moisture (about 70%) and an ambient temperature of between 20 and 25 º C. Usually compact fluorescent lights or LED lamps are used, which emit a constant and homogeneous light, allowing the plant to develop healthy and resistant roots.
The third phase, called "vegetative phase", has a duration of 2-8 weeks (always depending on the cultivated species) is usually associated to the transplantation in pot. The development of roots during this period is of paramount importance and of absolute priority. The humidity at about 50% and the temperature of the environment between 20 and 24 º C, are particularly important if you want to develop female plants (in case you are using regular seeds).
The 6-12 weeks following the vegetative phase, are those of the blooming, in which the plant produces its buds. It is essential to know that at this same stage the plants will provide their first indications on their sex: in the first 2 weeks, you can see the development of pistils if the plant is female, small protuberances on the inflorescence if the plant is male. If both sexes appear on the same inflorescence, there would be a case of hermaphroditism and the plant should be removed from the crop immediately. During the flowering phase, it is recommended to keep the humidity at 40-50% and the ambient temperature between 20 and 28° C.
The phase of the collection usually remains between the 7 and the 11 weeks, but in order to verify if the inflorescences are actually ready to be cut by the plant and subsequently exiled, there are a couple of devices which should be taken into account: the inflorescences to be considered mature, must have trichomes (visible through a magnifying glass) which must be covered by a white coating very similar to frost or dew. If these characteristics are present, then the inflorescences can be collected and exited. If the trichomes do not have to be yet sprouted or if they are not covered with "frost", it means that the inflorescence needs some other day of maturation.
