About Hemp
Cannabis sativa (hemp) is an annual herbaceous plant from the Cannabaceae family, valued for its fiber, seeds, and non-psychoactive compounds. It features a slender, upright stem with palmate leaves and inconspicuous flowers. It is ideal for outdoor cultivation or large greenhouses where its height and stature can fully develop.
Native range
Central and South Asia
Care tips
It requires full sun for at least 6-8 hours daily for optimal growth and good production. Watering should be regular, keeping the substrate moist but not waterlogged, especially during the vegetative growth and flowering stages. Use a well-draining, nutrient-rich substrate, preferably with a pH between 6.0 and 7.0. Avoid severe water stress, as it can negatively impact fiber quality and seed production.
