When growing a cannabis plant it is necessary to look after it in its entirety, starting from the buds and ending at the roots. If the most visible plant parts immediately catch our eye it is true that the most hidden ones can escape a daily superficial control. The roots, on the other hand, are one of the most delicate areas and at the same time important for having a healthy and productive plant.
Do you want to ensure the best care for your roots?
Here are some valuable advice that came directly from our growers.
Especially those who cultivate on the ground could neglect a careful control of the roots and find themselves discovering a problem of malabsorption or excessive humidity when the situation is now unsavable. One of the most difficult aspects of cultivation at home to manage is certainly the care of the roots which must be done keeping in mind various parameters such as distribution of the root system, management of air exchanges, humidity, water pH. and protection (also of this part of the plant system) from diseases such as fungi and parasites. Always remember that healthy roots mean strong and above all plantsa good production of inflorescences which (if well fed in growth) will be rich in terpenes and cannabinoids such as THC and CBD; so read well how to preserve and encourage the good functioning and survival of this too undervalued part of the plant.
Root system structure (tips to avoid root entanglement)
The structure of the roots and their way of distribution in the soil is very important to ensure correct absorption and the right distribution of nutrients to the whole plant. The more the plant grows, the more it is expected to find a vast and strong network of roots to support the stem, branches and our precious buds. Usually the root system is not prolific when it is unable to absorb water and nutrients because it is found to be contained in a too narrow space, in practice if the volume of soil available is too small you find yourself having very tangled and rolled up roots. themselves. If you see that your seedling is suffering from nutritional deficiencies or is not looking healthy, look at the roots, proceed to remove the bulk of the tangle and think of a transfer in a more spacious environment, in this way the underground parts of the plant will have more vital space and it will regain vigor. And if you want to be really smart, remember that prevention is always better than cure, so plan several decantings following the growth of the roots to ensure that your cannabis always has the right space to grow.
Moisture management and underground air recirculation
A very important and precariously balanced environmental factor in the marijuana growing system is undoubtedly humidity. Plants need water to grow but at the same time if they are excessively irrigated the roots can rot or may be more prone to the development of diseases and external aggressions. As we have pointed out in this article on the secrets of germination, the trick to maintaining proper irrigation is to avoid stagnation in any case and facilitate air circulation, to do this it is important that indoor crops are done inside pots or tubs. equipped with an effective ventilation system but also that the soil is of excellent quality. One way to ensure airflow and improve moisture management is definitely growing in a coir substrate.
Why do cannabis roots turn brown
The color of healthy cannabis roots of a nice shiny white. Those who grow in hydroponics and always have this part of the plant in sight know that seeing the roots turn color and turn red or brown is never a good sign. For both classic soil crops and more modern ones, the change in tone of the root system can be an indication of high nutrient levels, rot and bacterial production or fungal development. Often these latter problems are also accompanied by a rotten smell that triggers a highly motivated fear in the prudent grower. Root rot can affect both indoor and outdoor plants. Often it is related to ineffective drainage and fluid stagnationwhich lead to the development of harmful fungi and bacteria in the soil. In these cases it is necessary to reclaim the entire system, adopt alternative solutions to ensure air and healthier irrigation for the roots.
