Cannabis cultivation: Flowering

In the pre-flowering stage with a magnifying glass, we can detect the primordia or early flowers that give way to flowering proper when the plant reaches adulthood. Cannabis is a dioecious plant, which means that we can divide plants into two sexes: female and male. As soon as we detect that a plant is male, we must eliminate it, unless we want to make our crosses or obtain seeds. In this case, you must isolate the male plant from the female ones so that they do not accidentally pollinate themselves.

As we can see in the photograph, both plants have flowers. In the case of the male plant, it tends to show its pre-flowers in the form of small sachets that form in the internodes of the plant. In other cases, once the flowering in a female plant has entered. We should not trust ourselves because if we discover some small bananas that stand out from the floral part upwards, we would be facing another variety of male flowers that can spoil our harvest. If this happens, we can remove these bananas with a pair of tweezers, but if they keep coming out the best solution is to treat the plant as a male and cut it to prevent it from pollinating the females. The female flowers are made up of buds and the protruding hairs can be of various shades (white, orange, bluish).

During the flowering period, we must change the fertilizer that we used during growth, richer in nitrogen, as we saw in the post of vegetative growth. Now in flowering, it is convenient to use a flowering bonus rich in phosphorus and potassium to achieve more abundant flowers (buds). In addition, there are other flowering stimulators rich in micronutrients, phytohormones and chelates that help improve the organoleptic characteristics of the plant: 

  • more resin
  • flavor enhancers
  • the better aroma
  • more compact flowering.

Outdoor Flowering (cannabis)

At some points in the geography, the climate allows cultivation throughout the year. But in a standard crop from spring to autumn in the northern hemisphere, flowering begins between the beginning of July and the end of July, ending between mid or late September. The most Fast, for example, the majority of the indica and hybrids with a high percentage of indica. However, the sativa and combinations with a high rate of sativa can extend their flowering until the middle or end of November.

As we have explained, it is important to consider the way in which the weather can affect the development of our plant. Therefore we must think that flowering occurs in summer and in some places, the heat can be more extreme than in others. Thus in areas from high temperatures, we must protect the roots of our plants in flower pots that are large or white ( white square pot or white round pot ) so that they absorb less heat or use smart pots to aerate the roots and perform a natural pruning on them. 

One trick is to raise the pot or pot a little off the ground with small chocks and maintain a gap with walls that emit heat and do not allow natural air currents. Irrigation must be done at night to avoid evaporation and so that the earth does not heat up excessively since water has a high conductivity. On the other hand, we have to take into account that the months from September to October are colder but more prone to rain, storms, or winds. For this fact, we must be proactive and fasten the plants with ropes to the ground or trees. Protect them from the wind and rain since the latter can favor the appearance of molds that rot the buds.

Pest

Control pests, it is better to carry out a previous control using preventive insecticides such as neem oil before flowering or just at the beginning. We can also use bacteria-based products such as bactobloom that, at the same time, facilitate the feeding of the plant protects them from the attack of pathogens in the roots. In this case, the maxim of prevention is better than curing takes on real meaning, since if during flowering we are unlucky enough to have a plague, we should use insecticide products that can alter both the quality and quantity of our harvest.

Indoor Flowering (cannabis)

Plants are sexually adult between the fourth and sixth weeks of growth. This is the moment in which we must change the photoperiod from 18 to 12 hours to enhance flowering. We have seen that some sativa species have a slower flowering, to help compact their flowering and avoid soft and spiky buds during the last weeks, we can venture to reduce the light they receive to 11 or 10 hours. As the buds are taking shape, we also have to gradually reduce the humidity of the environment in a ratio between 40% and 55%, increase ventilation and maintain an optimal temperature between 19-25oC to avoid molds and fungi that ruin our harvest.

Flowering Automatic Plants (cannabis)

The fundamental characteristic of these plants is that they are smaller in size and have faster blooms. Therefore their needs, even when grown outdoors or indoors, are different from photo-dependent plants or the classic cycle.

The need for nutrients for automatic plants is lower. Therefore, if we use excellent cannabis fertilizer, we must use a lower dose than that suggested by the manufacturer. We can also use a specific fertilizer for automatic plants

Myths and legends

We have created this section to discern between myths and legends that run across the network and are false, without scientific foundations and also dangerous for our cultivation. If we put them into practice, we will spoil much of the potential of our cultivation or, in more severe cases, the entire harvest. Some of them are: “Plucking leaves, not watering and damaging the plant by cutting branches or stems” only serves to stress the plant, weakening it and reduce its production. The leaves are necessary for the production of chlorophyll, and that the plant is healthy and strong, it is entirely false. When the leaves are removed, the buds become larger. What happens is that when leafing a plant, there is an optical effect that makes it seem that the bud is somewhat more substantial. But is nothing more than an optical illusion. And these corrupt practices affect the performance of the plant and the quality of the grass. We should not confuse cutting a plant or parts of it with making a Pruning is a guided process.

What really should concern us is to provide a correct diet and hydration to the crop from start to finish.
