Marijuana plants are normally cultivated for their trichomes which contain the highest amount of THC than any other part of the plant. The goal of any grower that cultivates cannabis for harvesting buds is to grow plants that will flower and have a high content of THC. It is possible to misjudge the potency of a particular cannabis plant by simply paying attention to appearance. Aspects such as bud size, trichome odour, coloration and density are not an indication of THC concentration in marijuana plants. Generally, genetics plays a major role in the quality of yields that you will harvest after growing marijuana. Although it is possible to manipulate traits through crossing of various strains of marijuana, the best way to increase THC potency in cannabis crops is to create an enabling growing environment.
Like any other plants, cannabis requires an ideal environment to fully mature and develop trichomes. The chemical composition of marijuana buds primarily depends on whether optimal humidity, temperature and light intensity were provided for the plants during growth. In order to facilitate a good environment for cannabis plants, it is important to first of all understand the particular requirements of the strain that you intend to cultivate. Given that cannabis has spread throughout the world, this is probably one of the few plants that have mastered how to adapt and survive in different kinds of environments.
It has been found that marijuana strains that are grown in high latitude regions seem to possess a high degree of potency. However, regardless of the particular environment that cannabis plants are grown, the important thing is to ensure that the right growth conditions are facilitated. On average, most strains survive with temperature that ranges between 15 and 30oC. When provided with a full light spectrum along with ideal temperature and humid conditions, female marijuana plants direct their energy to THC production within trichomes. In addition, ideal growing conditions cause hormonal changes to occur in marijuana plants which further causes the conversion of cannabidol (CBD) and cannabichromene (CBC) into THC.
Apart from light intensity, temperature and humidity, it is possible to increase THC content in marijuana by simply meeting nutritional requires of the plants. Soil nutrition can be supplemented with fertilizers when the fertility of the soil being used for cultivation is low. Potassium silicate is one of the fertilizers that have been found to give marijuana plants more THC potency than those cultivated with no fertilizer. However, phosphorus soil additives benefit cannabis plants the most during the flowering phase, and they can be complemented with a minimal amount of potassium and nitrogen plant foods. It is important to apply fertilisers with moderation because cannabis plants that are intoxicated with soil additives are not only of low yield, but this can also impair the pace of growth.
In general, THC potency can be enhanced by providing the right growth requirements for cannabis plants. Keep in mind that bud cultivation of marijuana plants is best achieved by growing female plants alone. Mixing both male and female plants defeats the whole purpose of harvesting THC rich trichomes because pollinated female plants devote energy to production of seeds.
