Cannabis, an annual flowering plant, is native to Central Asia and the Indian subcontinent. The plant has psychoactive (affecting spirit) properties and is used for industrial, recreational and medical purposes.
The three most common types are Cannabis sativa, Cannabis indica and wild cannabis.
Marijuana grows in hotter climates, with longer days and plenty of sunshine. Therefore, it first appeared in countries near the equator, such as Colombia, Mexico and Thailand. These plants are generally 8-12 feet long and have long, thin, fingerlike leaves that help them capture as much sunlight as possible. They take a long time to grow, but the yield is high, so planting is rewarding. They bloom in autumn, when the nights are longer and they die soon after flowering. The bud of Indian hemp is loose, not dense and light. Because of its main psychoactive compound tetrahydrocannabinol (THC), Indian hemp is described as having a refreshing or uplifting effect when eaten.
Indian hemp originated in the Hindu Kush Mountains in Central Asia, where the environment is harsh. Today, it is widely distributed in countries 30 degrees north of the equator, such as Afghanistan, Türkiye and Morocco. In order to protect themselves from the harsh environment, Indian hemp produces resin, which is a viscous organic substance with high density in cannabinoid, so that Indian hemp has strong mental activity when taken.
This plant usually grows to four feet high, much shorter than the hemp leaves. The leaves are wide, round, dark green, and the seeds are marble. They are very sensitive to changes in light, similar to alfalfa. They only bloom in autumn and die soon after flowering. The bud of Indian hemp is more compact and shorter than that of common hemp. When you touch these buds, they look fuller, stronger and purple. Unlike ordinary cannabis, Indian cannabis is said to have the effect of relaxing and calming muscles.
Finally, wild cannabis originating in Russia is not as common as Indian or ordinary cannabis. This plant usually grows to two feet high and has short petioles, similar to Indian hemp, and is very suitable for outdoor growth. It has a wild and unbranched appearance, making it highly resistant to pests and diseases.
An important difference between Oxytropis and other species is that Oxytropis is self flowering; As time goes by, they will automatically enter the flowering state (generally within 21-30 days), flowering throughout the year until death, while other species need to change the daytime sunshine to enter the flowering stage. Wild hemp is harvested 10 weeks after planting. Wild cannabis has less psychoactive properties, so it is not used for recreational purposes. Instead, wild cannabis varieties were used to create hybrid species. Hybrid is a hybrid of hemp, which has both Indian hemp gene and common hemp gene. These hybrids are called Indian type dominant species, common type dominant species or balanced type, depending on their characteristics.
The cannabis plant remained stationary after receiving at least 12 hours of sunlight. At this stage, male plants are very similar to female plants, and it is difficult to distinguish them, although female plants are more fertile and blossom later than male plants. As the days get shorter and the nights get longer (in autumn), the plants enter the flowering period. At this stage, the density of the upper leaves of the plant starts to vary, and the leaves of male plants are less than those of female plants. Male flowers long, loosely clustered, 6-12 inches long; While female flowers are compact, densely clustered. The main sources of cannabinoids are unfertilized flower heads, flower buds and upper leaves of female plants.
When growing in the wild, the growth of cannabis is limited due to lack of nutrition. Compared with cultivated varieties, it produces only a small amount of seeds, fiber and oil. In order to maximize the quality of production for recreational and medical purposes, cannabis is produced by hydroponics in greenhouses or closed rooms, and environmental conditions (such as water, temperature and light) can be controlled.
