Cannabis sativa, commonly known as marijuana or hemp, is an annual herbaceous plant in the Cannabaceae family. Native to Central Asia, it has been cultivated for thousands of years for its fibers, seeds, and psychoactive properties. The plant prefers temperate climates and is known for its distinctive palmate leaves.
Cannabis sativa requires bright, direct light for optimal growth, ideally around 12 hours a day. It thrives in moderate temperatures and prefers a humid environment. Regular watering is necessary, but the soil should be allowed to dry out partially between waterings. Ensure good air circulation to prevent mold and mildew.
收成
Cannabis sativa is typically ready for harvest when the trichomes on the flowers turn from clear to a milky white or amber color, which usually occurs around 8-12 weeks after flowering begins. To harvest, cut the plant at the base and hang it upside down in a dark, well-ventilated area to dry. Ensure the drying environment has a humidity level of around 45-55% and a temperature of 60-70°F (15-21°C). After drying, the buds should be trimmed and cured in airtight containers for several weeks to enhance flavor and potency.
土壤
Cannabis sativa prefers well-draining loamy soil with a slightly acidic to neutral pH. The soil should be rich in organic matter to support its high nutrient needs. Good drainage is essential to prevent root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 3-1-2 during the vegetative stage. Fertilize regularly to support the plant's rapid growth, but reduce the frequency during the flowering stage.
换盆
Repot Cannabis sativa when the plant outgrows its current container, usually during the vegetative stage. Choose a larger pot with good drainage, and handle the roots carefully to avoid damage.
传播
Cannabis sativa can be propagated from seeds or cuttings. Seeds should be germinated in a warm, moist environment, while cuttings can be rooted in water or a suitable growing medium. Propagation is best done during the vegetative stage.
修剪
Pruning is essential for Cannabis sativa to promote bushier growth and increase yield. Remove any dead or yellowing leaves and trim the top to encourage lateral branching. Prune regularly during the vegetative stage.
毒性
Cannabis sativa is not toxic to pets or humans, but its psychoactive properties can cause adverse effects if ingested in large quantities. Keep the plant out of reach of children and pets to avoid accidental ingestion.
额外的
Cannabis sativa is sensitive to light cycles, which influence its growth stages. Ensure a consistent light schedule to avoid stressing the plant. Additionally, monitor for pests such as spider mites and aphids, and treat promptly if detected.
