Cannabis care during the growing season
The most favorable light regime for the growing season is 18/6. However, quite often growers completely remove the night period from the “diet” of the plant, increasing the amount of light up to 24 hours. But it is worth noting that there is no reliable information about the improvement in plant growth under such lighting.
Also, during the growing season, hemp needs a predominance of the blue spectrum of light. If it is not enough, it will stretch up disproportionately. The number of secondary shoots will be minimal, and the plant itself will be weak. To prevent this from happening, professionals recommend using special bicolor phytolamps, in which the blue spectrum of light with a wavelength of 450 nm dominates.
During the growing season, different types of cannabis are comfortable at different temperatures. These differences have arisen as a result of the different climatic conditions of the natural habitat. Indica is more adapted to low temperatures, sativa to high temperatures.
For indica and autoflowering varieties, a favorable thermometer reading is considered to be a value of 20-28 degrees. At night, it is desirable to lower the temperature to 18-24 degrees. Such fluctuations will promote vigorous and healthy growth of the plant.
Sativa varieties of marijuana feel comfortable during the day at temperatures of 22-30 degrees. At night, the thermometer should not drop below 20, since this will have an extremely negative effect on the development of the plant.
Favorable humidity level for vegetation is 50-70%. When growing a tropical sativa, the grower should focus on the upper values of this range. Indica prefers a drier climate. This feature should certainly be taken into account during outdoor cultivation, choosing a variety depending on the climatic characteristics of the planting site.
During the growing season, hemp needs a lot of water. Giving her the required amount, the main thing is not to overdo it. Excessive watering can easily lead to waterlogging of the soil and, as a result, root rot.
Watering cannabis should only be done when the top layer of the soil is completely dry at a depth of 2-3 cm. You can determine the readiness for the next watering with your finger, immersing it in the soil at the indicated depth. If it is dry, then the time for watering has come, and if it is wet, then you should wait a few more days.
During the growing season, hemp needs a lot of nitrogen. Phosphorus and potassium are in second place. It is also important not to overdo it with plant nutrition, because an excess of nutrients will certainly lead to their blockage.
The best solution is to use a specially prepared soil mixture, which is already rich in all the substances the plant needs. In this case, you will have to feed him only with a long growing season. To do this, it is best to use organic fertilizers of a complex type, which can be easily found on the Internet on thematic resources.
As you know, plants breathe carbon dioxide. They need it as much as a person needs oxygen. If the plant is grown in a confined space, then its regular supply can only be ensured with the help of good ventilation.
At a low CO2 concentration, the process of photosynthesis will be sluggish and unproductive. Marijuana will receive little vital energy, which will negatively affect its development.
