Abstract
Given that cannabinoids, which are derived from Cannabis, have therapeutic properties, cannabis production is an expanding global enterprise for the medical industry.
Historically speaking, cannabis has been an illegal crop in Thailand, which has resulted in a lack of scientific literature on cultivation, specifically with regard to the growing media and to crop management.
In order to evaluate the mixed growing media to determine the growth and cannabinoid content of cannabis production, the trials were conducted in an indoor system.
Treatments with different compositions of growing substrate, consisting of six commercially available growth media (peat-based (TS4), coconut coir (CC), coconut coir dust (CCD), TS4 + CC (1:1), CCD + CC (1:1), and TS4 + CCD (1:1)), were investigated in order to determine the plant heights, plant diameters, the numbers of branches, the stem diameters, Fv/Fm, the SPAD values, the roots, and the nutrition contents of the substrate media.
Furthermore, at the end of the experiment, the fresh weight, the dry weight, and the cannabinoid contents (THC and CBD) of the plants were measured based upon the different compositions of the growing media in an indoor pot cultivation system.
The highest plant growth was achieved by only using white peat (TS4), and this was followed by TS4 + CCD (1:1). In the future, there will be a demand for organic green fibers to partly replace fractionated peat, which showed a genotype-specific option for plant development given that there had been comparable plant growth and cannabinoid content when compared to the commercially peat-based, which contain standard media.
