Compares selfing with intercrossing for producing feminized seed from two Thai landrace accessions of Hang Kra Rok cannabis, one from Bangkok and one from Sakon Nakhon. Female cuttings were treated with colloidal silver to induce male flowers, and the progeny were grown in a plant factory with artificial lighting. Both selfed lines and the Sakon Nakhon by Bangkok cross gave 100% female plants, while the reciprocal cross produced one hermaphrodite (5.6%). Dry inflorescence weight did not differ between treatments, and the Bangkok selfed line had the highest THC content at 6.58%. The plants were grown under artificial light, so the chemistry is not field chemistry.
