Stimulating the flowering of marijuana

The cannabis bloom is the final stage of the cannabis life cycle, a long-awaited time when the grower sees firsthand the fruits of his labors. However, sometimes there are disruptions in the life cycle of the plant, and flowering is delayed for not entirely clear reasons. In outdoor, a delay in the beginning of flowering is fraught with loss of yield – the inflorescences simply do not have time to ripen before the onset of cold weather. In indoor everything is not so critical, but everyone has any plans related to the fact that by a certain date the harvest will already be obtained. And here – here …

Changing the light mode

For photoperiodic varieties, a reduction in daylight hours is the main signal for the beginning of flowering. Indoors this is easy and simple to achieve: the plants are switched to 12/12 light and bloom over the next two weeks or so. Autoflowering cannabis strains do not need this stimulation: as a rule, during the entire cycle, the day / night ratio is maintained at 18/6 or even 20/4. But if the plants do not bloom, after the period specified by the manufacturer, it is quite possible to try to make them bloom, using the same technique as for fotik – perhaps there was some kind of failure in genetics and the autoflowering gene “did not work.”

When growing marijuana outdoors, such a number, of course, will not work. Nevertheless, it is still possible to stimulate plants with light (or rather, darkness); for this, the darkening method is used – cannabis bushes are covered with dark bags or bags. The most obvious and gentle way is to lengthen the darkness of the day. That is, the bags are put on in the morning or in the evening (or so and so) during twilight, when the sun is no longer hot, but it is still light outside. This is a more natural way.

The second way is more radical. The plant is deprived of light for a long time (usually two to three days), and at the same time experiences severe stress. The transition to color is a natural reaction to unfavorable conditions for many plants. After the beginning of flowering, it is not required to continue these procedures, it is unlikely to stop. When using plastic bags or garbage bags, it is necessary to provide the plant with ventilation, make some holes. You can also use bags made of lightweight agrotextile or similar material. They are also denser and ventilation will be better.

For partisan plantings, this method will be quite difficult and, perhaps, risky: you will often have to visit the plot, and black bags, among the greenery, can draw unnecessary attention to the plantings.

Chemical stimulation of flowering

Correct feeding of hemp, in any case, will benefit the plants. Strong, healthy plants are more ready to bloom than emaciated, undernourished dead plants. In preparation for bloom, you should increase the amount of phosphorus and potassium in the top dressing. They are not only consumed in greater quantities by flowering marijuana, but they can also push it towards the beginning of flowering. The greatest number of positive reviews, in this regard, is received by potassium monophosphate – a useful fertilizer and at the same time a hemp flowering stimulator.

This group also includes complex fertilizers for the flowering phase, in particular, the flowering stimulator Bio Bloom. It is a versatile stimulant suitable for use in hydroponic installations, soil and soilless substrates. Thanks to the biological activator included in the fertilizer, the intensity of flowering increases, the size of the inflorescences increases, the absorption of nutrients by the plant (especially calcium) is accelerated, and the metabolism is accelerated. Bio Bloom is discontinued 10 days before the planned harvest date. At this time, rinsing with clean water is carried out to remove drug residues from the plant.

Minerals alone, perhaps, are not able to 100% guarantee the beginning of flowering, but the water wears away the stone, the bird pecks by the grain, etc. The creation of the most favorable conditions, in combination with other factors, will undoubtedly have a positive effect on the timely start of the process. From organic substances, bird droppings are recommended for the same purposes, with which, however, one must be very careful. This is a very concentrated fertilizer, in case of an overdose, you can easily burn the plants.

Hormonal stimulants
Theoretically, the hormonal picture of the beginning of flowering of photoperiodic plants is as follows: flowering hormones are produced in the dark, and decompose in the daytime. As the daylight hours decrease, they no longer have time to be destroyed during this time, but are synthesized, due to the lengthening of the nights, more and more. They begin to accumulate in the plant, and, having reached a critical amount, give the command to start flowering. Apparently autoflowers produce hormones on a large scale. Thus, they begin to accumulate almost immediately, and as soon as the plant is physiologically ready for flowering, it blooms.

Florigen, vernalin, gibberellin, and anthesin are among the hormones that influence flowering. More precisely, in the sources they are called “hypothetical hormone-like molecules” and are not fully understood. However, this does not prevent the use of these substances and their synthetic analogs to stimulate cannabis flowering. They are not sold in their pure form, but are included in most biostimulating additives and flowering inducers.

The most stable result is provided by an integrated approach: optimal growing conditions, correct lighting regime, timely and complete feeding, competent use of growth and flowering stimulants.
