Not excessively. Compared to those growing from automatic seeds, they are certainly more demanding, but they are generally also very resistant. The hemp plant enters the flowering phase only after a first cycle of 18 hours of light, and a second one of hours 6 of darkness and then again 12 hours of light and 12 hours of darkness, in order for the blooming to take place. Resin production and flowering based on light cycles are key factors in determining flowering time and final yield.
Therefore, in case of outdoor cultivation, for example in a garden, a single flowering cycle will be possible, starting during the summer to have the plant blooming in early September, as the only source of light available is the sun. The ideal time for planting weed seeds outdoors is early spring, after the last frost, to ensure successful germination and growth.
Growing cannabis successfully requires attention to strain selection and environmental factors. The situation changes for indoor inflorescence production. The advantages of this cultivation technique are that breeders can have control over all the variables that influence the growth and blooming process of the plant: the power and length of the lighting cycle, temperature, and humidity. Monitoring electrical conductivity of the nutrient solution is important to ensure proper nutrient uptake and healthy root development. It is also essential to avoid overwatering to prevent root rot.
Feminized plants live longer than those from autoflowering seeds, making them more vulnerable to pests. To produce high-quality buds organically, indoor or greenhouse growing is usually preferred for these plants. The development of feminized seeds revolutionized industrial cannabis cultivation, allowing large-scale production of various strains with greater efficiency.
