Cannabis is very particular and demanding when it comes to soil quality and texture. Let us discuss the ways you can make sure that all variables meet the requirements.
The most suitable conditions for cannabis are plenty of light and loamy soils. The latter component should contain sand, silt, and clay in a proportion of 40:40:20. Sand is viewed as the most significant ingredient of soils that consists of fractions mostly equal to 0.05-2 mm. Silt is smaller than sand measuring 0.002-0.05mm, and clay particles are 0.002 mm in diameter.
The pressing issue here is stability and drainage of the soil. You should add gravel with a diameter of 2-75 mm to improve these characteristics of the soil. If your goal is to grow weed fast, you need to use commercial soils instead of local ones, as these soils are rich in valuable additives.
Regulate soil pH
The suitable pH conditions for cannabis vary from 5.5 to 6.5. It is important to make sure that the proportion of nutrients provides the pH within these limits. Otherwise, you will face negative consequences resulting in low quality and yield.
To normalize the proportions (if the soil contains too much alkaline ingredients in comparison with acidic ones), you should use sulphuric acid to lower the pH. In case if soil pH is overly acid, the solution is to add calcium carbonate. It should be noted that for fast weed growing, you should pay attention to all the requirements to avoid toxicities or deficiencies.
Without constant steaming of your soils, it is impossible to maintain a suitable soil status. Various bacteria, insects, and even fungi attack your soil. Please also note that commercial soils do not have these problems, as they are intended for cannabis cultivation, unlike local lands. Another effective method to enrich the soils is to add organic compounds as well as microbes and insects that kill pests.
Solarization is considered one of the alternative methods for sterilizing outdoor soils. You should divide the soil into pieces, then water it and put plastic on this area. These actions are required to achieve 46°C (114°F) for a period of four-six weeks. To achieve a sterilizing effect, you should constantly control the temperature level.
You can sterilize soil by the means of steam if the solarization method is not acceptable due to time limits. This method involves special tools for large areas, but household steaming means can be used as well.
