Cannabis (botany)
Cannabis (scientific name: Cannabis, sp.) is a herbaceous plant in the Cannabidaceae family. The leaves are rounded, deeply lobed towards the stalk, with many lobes. The flowers are green. The male and female inflorescences are separate plants. Cannabis is harvested for various purposes, such as the stems being used to make fiber, and the roots being boiled to relieve bone pain and gout. Dried leaves and female inflorescences are smoked and have properties that can help treat diabetes, high blood pressure, and cancer. Cannabis produces large amounts of tetrahydrocannabinol (THC). High amounts of THC cause a euphoria, which makes it a popular plant for recreational use, alternative medicine, and clinical research.
Botanical characteristics
Annual herbaceous plant, erect stem, 0.3-3 m tall. Young stems are green, brown when old, with gray-green hairs and rarely branching. The stems, leaves and flowers have a terpene aroma.
Simple leaves, palmate, alternate, deeply concave to the base of the leaf into 3-11 lobes, each lobed oval, 0.3-1.5 cm wide and 6-10 cm long, with serrated edges. The upper surface of the leaf is green and purple, and the underside of the leaf is white.
The flowers are unisexual, on different plants, in clusters at the branch forks and shoot tips.
Male cannabis can be identified by the joints between the stem and the branches, which are called “eggs” because they are round, more than 2 eggs, or sometimes in clusters.
Female cannabis has white hairs, when the hairs are old they will be orange, tightly packed at the branch forks and shoot tips. It contains a lot of tetrahydrocannabinol (THC).
White young seeds, brown mature seeds, with a watermelon-like pattern.
What are Feminized Seeds?
Feminized Seeds are cannabis seeds that have been feminized (95%). This is done using colloidal silver or silver thiosulfate to cause the female plant to produce pollen sacs with male chromosomes, which are then crossed with another female plant to produce seed.
What is the difference between Autoflower and Photoperiod?
Autoflower and Photoperiod differ in the number of hours of light the cannabis plant receives before entering the pre-flower phase. Autoflower cannabis plants, or Cannabis ruderalis, can pre-flower when receiving 6-24 hours of light per day, while Photoperiod cannabis plants, or Cannabis sativa and Cannabis indica, will not pre-flower when receiving more than 12 hours of light per day.
Taxonomy
Cannabis is the name of a plant in the genus Cannabis. There are three species in the genus: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. All three species have different origins. Cannabis sativa is a plant native to East Asia, but some believe that its origin is in Southeast Asia, in the Phu Phan mountain range in Sakon Nakhon Province, Thailand. Cannabis indica is a temperate plant, originating in the Hindu Kush Mountains. Cannabis ruderalis is native to Eastern Europe and Russia.
