So, indoors, the grower takes on the responsibilities of nature itself. In the wild, every cannabis population can adapt to the local climate over several generations. Indoor seeds do not have such an opportunity, and their only hope is a correctly selected temperature regime, as well as regulated air humidity.
Temperature Condition and Why it Matters?
- At the seedling stage, seeds and seedlings thrive at temperatures of 20°C at night and up to 28°C during the day.
- During the growing season, it is recommended to maintain a temperature of 18-20°С at night, and up to 26°С during the day.
- For flowering plants, the permissible night temperature is 18°С, daytime up to 26°С.
Rule: the difference between night and day temperatures should not exceed 10°C.
The correct temperature regime is one of the decisive factors for the development and productivity of plants since the ability of cannabis to absorb nutrients from the soil depends on the temperature. Biological scientists estimate that the performance of a marijuana bush can decrease by 50% if the temperature is abnormal.
How do I Regulate the Temperature?
A hot grow house is usually cooled using hoods – it is especially necessary when using hot lamps, which can raise the temperature by as much as 10°C, or even more. In larger grow rooms, it is sometimes possible to get by with blower fans and ventilation slots, but small cbd boxes almost always need a hood. Also, during the summer, many indoor growers light up their plants at night, allowing the hotter daytime to come at night in the grow box – it also allows them to gain a few degrees on the cooler side.
A cold grow house can be slightly warmed up using any heater. It is undesirable to use heat guns and filaments and open fire – drying the air is undesirable.
Suitable Humidity and How to Achieve it?
The amount of suspended moisture in the air affects the health and well-being of any organism. Miraculously, compared to humans, hemp needs … the same humid air: 40-60%. At flowering, it is desirable to reduce this figure to 45-50%. Where to begin? Of course, from the measurement. You will need a hygrometer or thermo-hygrometer. This device is inexpensive and can be purchased on the Internet or in a gardening store.
To increase the humidity, wide containers with water are used (a large evaporation area is needed), which are placed in the grow box. Alternatively, it will help you hang a damp towel in the box. It’s not a bad idea to spray the walls with water from a spray bottle (preferably at night if the lamp generates a lot of heat). We use dehumidifiers to reduce humidity. With a slight deviation, sometimes the issue is resolved with the help of a more powerful hood, as well as careful aeration of the plant tops (blower fan).
Lifehack: if you lower the moisture content to 20-25% in the last two weeks of flowering, the inflorescence produces more resin – this way, the plants prevent moisture loss by plugging the pores with thick essential oils.
Is it Possible to Grow Cannabis Without Moisture and Temperature Problems?
In theory, any particular room can accidentally have a suitable microclimate. If the plants show no signs of stress and are thriving, the grower may be in luck. But if there are any signs of ailment, it is, first of all, recommended to check the pH of the soil, as well as the temperature and humidity of the air.
The Bottom Line
It is the fact that behind every product, there is a lot of effort. The same is true for CBD products. Whenever you go to the market and explore some beautiful CBD, hemp, and marijuana packaging boxes, you do not understand the efforts behind preparing these top-class products. Here, we have tried to tell you the efforts behind preparing cannabis. There is a long process even after that to convert cannabis into useful CBD products. After such a long process, you get what you expect from CBD product manufacturers.
