It is not enough to buy quality hemp seeds, you still need to know how to grow them correctly. One of the main stages in the development of marijuana is flowering. After all, it is at this time that its cones are formed, they pass into the active period of trichome development and, of course, THC increases. The flowering of hemp is the peak of its maturity. Therefore, the grower must not miss the harvest moment.
What types of cannabis blooms are there?
These types fall into two broad categories:
It occurs at a time when daylight hours are reduced to 12 hours. If marijuana is in the open field, then this moment comes in late summer or at the beginning of the scales. Most varieties begin to bloom in August and are harvested in November. But there are also slower plants. For example, the sativa cannabis bloom takes longer – up to three months. Therefore, some of the varieties in the middle climatic zone cannot be grown (outdoors) due to the severe cold snap in the fall. There are also very fast flowering varieties. Indica cannabis blooms sometimes in as little as 8-10 weeks.
As the name suggests, flowering occurs automatically without taking into account the factor of the length of the sunny day. After a couple of weeks at the vegetative growth stage, the flowering period of the cannabis begins. This specific feature was obtained by crossing the original varieties with Rudealis. Autoflowering strains are more popular with growers as they require less maintenance.
Autoflowering blooms should be considered separately. By themselves, they are genetically modified. The flowering time of cannabis in this case does not depend on what time of year it is, how many light hours there are in the day, and what method of cultivation will be chosen by the grower. The flowering period of cannabis is 8 to 10 weeks. The advantage of autoflowering is that after harvesting, you can plant the same area several times until the days get very cold.
Marijuana flowering – three main stages
Experts identify 3 distinct flowering periods:
Pre-flowering (beginning of flowering of hemp);
Pre-flowering is the period when the first buds are just beginning to form on the bushes. In most cases, inflorescences form between the fourth and sixth nodes. The time that marijuana is in its pre-flowering period is approximately 2 weeks, but may vary from cultivar to cultivar. There are also those in which the second stage begins in just a couple of days – flowering. During flowering, a kind of cups are formed on the bush, which are located near the internodes. Sometimes the plant doesn’t want to bloom on its own, so growers have to stimulate the cannabis bloom.
Regular seeds have a pronounced sex of the plant during the flowering period. The male ones are covered with small balls, which outwardly very much resemble grapes. And for women, the formation of pistils is characteristic, which resemble small villi. It is the female plants that are of most interest to growers, as their inflorescences are high in THC and are very dense.
Characteristics of the Indica and Sativa Blossom
Even an inexperienced grower will tell you that Indica and Sativa are very different. Accordingly, during the flowering period, this is also unusually pronounced.
Indica blooms are orders of magnitude faster than Sativa blooms. Bushes are short, strong, bloom early and bloom much faster than Sativa. Vegetative growth is also much more active. The cool climate in which the Indica originally appeared prepared it to finish flowering during a rather cool season. Flowering begins mainly with a noticeable reduction in daylight hours, and ripening can occur until the first winter frost.
Sativa blooms are much less dependent on the light cycle, as they came to us from the evergreen tropics. Her vegetation is long, thanks to which the bushes sometimes grow up to six, or even seven meters in height.
Subtleties of care during the flowering of marijuana
The very time of the beginning of the flowering period of cannabis depends a lot on its vegetative phase. At this time, the main forces and energy of the plant are directed precisely to the formation of buds. When it comes to the flowering period of marijuana, it is important to use special fertilizers, since the bushes need a lot of nutrients. And already when the ripening period begins, feeding should be minimized. During this time, too much fertilization can only adversely affect the taste and aroma of cannabis.
There are some important tips for caring for blooming marijuana:
It is better to water the bushes often, but not very abundantly. Despite the fact that at this time they actively absorb moisture, do not flood them. In some cases, this contributes to the active formation of fungus and mold, which should be avoided in every possible way;
If the inflorescences are heavy and actively filled with resin (typical for some varieties), then you need to tie up the branches in time. Otherwise, they can simply break under their own weight;
For most varieties, it is recommended to maintain light hours within ten to twelve hours;
Indoors, the air temperature should be no more than 28 degrees during the day and at least 18 degrees at night. Experienced growers say that the most reasonable difference between day and night temperatures is up to 10 degrees;
Do not allow air humidity to be higher than 50%. This is important primarily for Indica. Sativa also tolerates higher humidity without problems. When it comes to hybrids, the moisture requirements are very individual;
It is better to use organic and natural fertilizers equally. This combination nourishes the bushes in the best way, they grow larger and have a higher yield.
Please note that some of the varieties are recommended to be placed in a completely dark room during the flowering period of marijuana in the last few weeks of flowering. Under these conditions, resin is produced much more actively. It is also worth remembering that it is during the flowering period of the hemp that the strongest characteristic odor is released, which differs depending on the variety. If marijuana is grown indoors, charcoal filters and air purifiers save the day. Although there are those varieties of cannabis that practically do not emit a characteristic odor during flowering.
