How long is cannabis growing?
Every grower needs to know how much cannabis grows. Only then he can plan the process of growing marijuana, calculating his own strength for its successful completion. But the development of cannabis, like any other plant, does not occur at precisely specified times. The life cycle of each plant is different. It depends on many factors, genetics and externals. 
The influence of various factors on the growth rate of marijuana
Seeds bank breeders provide the consumer with passport information about the variety that has been released. It is calculated on the basis of favorable growing conditions and proper indoor care. The slightest environmental changes or a mistake of the grower can negatively affect the growth speed rate of marijuana. This will lead to inconsistency of the data specified in the document.
The most likely cases, due to which the maturation of the cannabis bush may be delayed, include:
• Not ideal or different environmental conditions, which adversely affect the plant, creating difficulties for it;
• Cultivation takes place in open ground, where the life cycle of cannabis is certainly increasing for a number of reasons. It is worth remembering that all the passport data of the plant are calculated in Indore;
• Although many marijuana varieties are considered stable and reliable, they still have a small variation in phenotype. The duration of the flowering period or life cycle of some of them can be different from the most common variation;
• The rate of growth and development of marijuana are more dependent on the size of the root system. In large and spacious pots the plant will need more time to form strong and healthy roots. This will certainly extend its growing phase, due to which the crop will ripen later;
• Cannabis growth rate is very slow due to stress. After getting injured, an overabundance of nutrients, insufficient watering or any other grower’s mistake, cannabis stops its development. She begins to spend all her vitality on recovery, which delays any of the phases of her development;
• Low or high temperature. The development of cannabis is very much slowed down when the thermometer is below 15 and above 32 degrees. Even the indicators are close to these values can affect the growth rate of a plant;
• The use of different techniques to increase productivity almost always requires the plant to restore or redistribute vital energy. This is especially work for light or heavy stress training methods.
The growth rate of auto flowering marijuana varieties
The fastest varieties of marijuana are considered autoflowers. Due to the duration of the vegetation phase that is strictly established at the genetic level, they begin to bloom 2-4 weeks after seeds germination. The duration of this period can not be affected. That is why auto flowerings need to be closely protected from the stress. Even if the stump spends half of the veg phase to repair the damage, it will still bloom in the time specified by the genes. Only the duration of flowering can fluctuate for auto flowers, but, as a rule, deviations are no more than 1-2 weeks. It is also worth considering that auto flowers with prevailing indica genes will grow faster than sativa-dominant plants.
The approximate life cycle of indica dominant auto-flowers is:
• In the indoor - 7-9 weeks;
• In the outdoor - 8-10 weeks.
The way from seed germination to harvest of auto flowers with a predominance of sativa genes lasts:
• In the closed ground - 9-11 weeks;
• In the open ground - 10-12 weeks.
The growth rate of photoperiod marijuana varieties
The growth rate of photoperiodic plant depends on the light mode. In natural conditions, growth phase will certainly end in late July, early August. Then those daylight hours are reduced to 12-14 hours. The planting in open ground for each grower may differ since the time, then its duration will be different the same. The flowering period of photoperiodic is calculated at the genetic level, but it is also able to change under the influence of the factors. It will also differ of representatives of different genetics.
The life cycle of photoperiodic plants in the outdoor lasts:
• Pure sativa - 160-260 days;
• Pure indica - 80-120 days
• Hybrids with an approximate ratio of genes 50/50 - 120-160 days.
In a closed ground, each grower has the right to choose the duration of the vegetation period for photoperiodic plants. Theoretically, any plant can be in this stage of development so much time. Many gardeners transfer the plant into the flowering stage at the moment recommended by the manufacturer or upon reaching the maximum allowable growth. The ripening in indoor is a little faster than in the open growth. Most often this is due to a higher intensity of the light flux and less compact size of the bushes.
The lifespan of the photoperiodic plants in indoor is:
• Pure sativa - 150-240 days;
• Net indica - 70-105 days
• Hybrids with approximately equal gene ratios - 110-140 days.
