Air is one of the most determining factors in making a marijuana crop work. There are many factors that must be controlled if we want to obtain an abundant harvest and maximum quality, but air is one of the primary factors. In fact, in an interior cupboard, air can be the key to success or failure. In addition, within the air there are several variables that we must have under control, such as temperature, movement, humidity, CO2, odors, ions or ozone. The idea of the following article is to provide the reader with all the necessary information to keep the air of our crop under control.
Air in motion
If a healthy, abundant and high-quality harvest is to be achieved, we must control two essential factors such as ventilation and air circulation. Many novice growers do not give importance to the correct air circulation and, therefore, neglect this factor spoiling their harvest. Of course, experienced growers do know the importance of air and do not hesitate to devote their effort and money to setting up a ventilation system suitable for the needs of plants.
Keeping the air moving by providing plants with fresh outdoor air is of vital importance for plants to successfully develop their vital functions. Within the movement of air there are three main factors: stomas, circulation and ventilation. Stomas are like the muzzle of the plant, located on the underside of the leaves and are microscopically sized pores that regulate the amount of oxygen and carbon dioxide. On the other hand, the circulation is also very important because the leaves consume the CO2 around them in a few minutes.
Therefore, if the plants do not have new air loaded with CO2, the stomas will be blocked, and the correct development of the plant will be stopped. To prevent this from happening, we must keep the air constantly circulating in order to provide the plant with new air and not have to settle for the air that has already been used and is therefore devoid of CO2. Finally, the ventilation, which consists of nothing more than providing plants with fresh air from the outside by means of an extraction and intraction system that creates an air flow in the room.
This is necessary because plants transpire the water they absorb into the air, in a process similar to evaporation. In this way, if we don’t ventilate the room air, the ambient humidity would rise to 100%, blocking the stomachs and, therefore, the growth and development of the plants.
Another of the determining factors in the correct development of an indoor crop is the temperature. The ideal temperature range for a marijuana plant under normal conditions is 22 and 24 degrees. This temperature can be reduced at night if it does not fall below 8 °C, and during the day it can rise to 29 °C, if it increases further, the plant will be paralyzed. Therefore, it is necessary to control the temperature of the room with an accurate thermometer, which can be a day-night or maximum-minimum temperature drop, which measures temperature drops and maximum and minimum, an ideal option to keep the temperature of our indoor culture under control. Keeping the temperature of our wardrobe within the recommended ranges will determine the success or failure of our indoor.
Humidity is another of the most important factors for the correct development of plants. Depending on the temperature, the air retains a certain amount of moisture, that is why humidity is always relative. This variable in question is measured by the proportion between the amount of moisture in the air and the greater quantity of water that the air might contain at the same temperature.
The ratio is simple, the higher the temperature the more water can retain air; while, at a lower temperature, the less moisture it can contain. If we manage to maintain humidity levels between 50% and 60% during the growing period, and 40% and 50% during flowering, we will ensure a proper development in our harvest.
In fact, if moisture levels are low, this will be fatal to the development of the crop, and if moisture is higher than needed, fungi and other problems are likely to appear that will ruin our harvest. For this reason, it is essential the spindle of humidifiers and dehumidifiers that can correct the misalignments in the humidity percentages and ensure a correct development of the crop.
Carbon dioxide is always present around us. As a definition, it should be noted that this is a colorless, odorless and non-flammable gas found in the air we breathe in a proportion of 0.03 or 0.04%. If CO2 levels fall below 0.02%, the plant will not be able to carry out vital processes such as photosynthesis or its own growth.
This is since, during the biological and physiological process of plants, known as photosynthesis, carbon dioxide acts as a stimulant that transforms, by means of light, Co2 into glucose and oxygen, two of the main nutritional sustenance of plants. Specifically, marijuana is capable of supporting Co2 levels of up to 0.15%, a figure five times higher than the content of Co2 in the Earth’s atmosphere. This physiological characteristic means that, with higher levels of Co2, marijuana can withstand higher temperatures and increase its metabolic capacity and, therefore, its performance. It is therefore convenient to provide our plants with oxygenated air, clean and rich in co2. This can be very useful throughout the whole process, but especially in times of greater heat of the bulbs, since by applying Co2 we will avoid the paralysis of the biological processes of the plant.
Discretion is always one of the major allies of the cannabis grower. Therefore, it is always a good option to acquire an anti-odour filter or any system that helps us to avoid the expulsion of smells that alert neighbors or curious.
As every marijuana grower knows, indoor crops produce a lot of odour because the plants are in a small space and the aroma is concentrated and potent. To avoid the inconvenience in question, there are a whole series of possibilities and items that can make your growing room an imperceptible place for your neighbors and visitors.
Generally, extraction systems are used with an outlet to the outside and an active carbon filter that filters the air and removes the characteristic smell of marijuana. Another option is the negative ion generator or deionizer, although there is a wide variety of items such as tablet, liquid or spray anti-odour gels. Most of these products fight odors by changing the molecular structure of the air, so it doesn’t disguise the smell of marijuana, it kills it.
Controlling the parameters related to the air in our crop is vital important for the correct functioning of our growing cannabis indoor. If you control all the variables that have been discussed throughout the following article you will notice a big difference in the results of your crop. In fact, it will not only improve the quality, but also the growth, quantity and appearance of the crop.
