10 Points Should Pay Attentions Before Start Cannabis Plant Business

Morphological characteristics of cannabis
An annual erect herb with a height of 1-3 m, branches with longitudinal grooves, and dense gray-white affixed hair.
Leaves palmately lobed, lobulate lanceolate or linearly lanceolate, ca. 7-15 cm long, loculate longest, 0.5-2 cm wide, apex acuminate, base narrowly cuneate, surface dark green, slightly pubescent The back is densely covered with grayish white hair and becomes hairless. The edge has a thick serrated inwardly curved shape. The midrib and lateral veins are slightly sunken on the surface, and the back is raised. The petiole is 3-15 cm long and densely covered with grayish white hair; The stipules are linear.
Male inflorescences up to 25 cm; flowers yellow-green, perianth 5, membranous, glabrescent outside, stamens 5, filaments very short, anthers oblong; small stalks ca. 2-4 mm long; female flowers green; 1, tightly wrapped ovary, slightly small hair; ovary near spherical, outside the bread in the bracts. The achenes are covered by persistent yellow-brown bracts, the skin is crisp and the surface is finely textured.
The flowering period is from May to June, and the fruiting period is July.

Growing environment
1. Temperature: seeds can germinate at 1 ~ 3 ° C, suitable temperature is 25 ~ 30 ° C; seedlings can tolerate -3 ~ -5 ° C low temperature, suitable growth temperature of seedling stage 10 ~ 15 ° C; rapid growth period 19 ~ 23 ° C; Mature period 18 ~ 20 ° C. In the flowering period, if the temperature is -1 to -2 °C, the flower is dead and cannot form seeds.
2. Illumination: Cannabis is a hi-light, short-day crop, and late-maturing varieties are more sensitive to light. In production, the southern planting of northern plants is beneficial to increase fiber production.

Breeding method
Cannabis varies in the area and variety from planting to fiber harvesting. The growth period of varieties grown in China is generally 80-140 days. According to the characteristics of cannabis fertility, its life is divided into emergence period, seedling growth period, rapid growth period and maturity.
Emergence period: from sowing to emergence, under suitable field conditions, generally about 10 days.
Seedling growth period: From emergence to the 7-9th, the true leaves are developed into seedlings, which last for 30-40 days. The shoots grow slower and the roots develop faster.
Rapid growth period: from the end of the seedling growth period to the beginning of flowering, lasting about 55 days. Rapid elongation of the stem is the main stage of fiber production.
Maturity: Male plants from the beginning to the end of flowering, lasting 15-25 days, is the mature stage of the male plant, also known as the fiber accumulation and maturity. Female plants from flowering stage to seed maturation, lasting 30-40 days, is the key period for the formation of female grain yield; if used as fiber, when the following fruit begins to mature, it will reach the mature stage of the process.
