Ketama 'Beldia' 1990 is a landrace cannabis inbred line accession reproduced by the Real Seed Company, derived from Beldia landrace seeds originally collected in Ketama, Morocco in the early 1990s.
Cannabis cultivation
Cannabis cultivation is the growing of Cannabis sativa for fibre, seed, drug or multi-purpose use. Cannabis is a dioecious annual in the family Cannabaceae with a long history of agricultural use across Eurasia and, through later dispersal, every inhabited continent. Cultivation practices vary by use type, latitude, climate and legal context, ranging from rainfed smallholder fields integrated into mixed cropping systems to fully enclosed indoor production.
The crop is grown for several distinct end products, including bast fibre from the stem, seed for food and oil, drug preparations made from female inflorescences (such as ganja, charas, hashish and sinsemilla), and combinations of these. Modern commercial drug cultivation is largely based on F1 hybrid genetics propagated as clones, often grown indoors or in greenhouses, while landrace populations persist in traditional growing regions through ongoing mass selection by farmers. Outdoor production remains the dominant mode worldwide for fibre, seed and traditional drug cultivation, while indoor systems using artificial lighting became widespread in prohibition-era North America and Europe from the 1980s. read more →

Cannabis eradications
We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge, preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.
