In order to produce big, healthy buds, your cannabis plants need a healthy root system. This is where the plant absorbs essential nutrients and water that are necessary for growth. If you focus your energy on promoting and maintaining a healthy root system, you’re likely to have fewer problems and larger yields each cannabis grow cycle. Today we will discuss some of the most important aspects of root health in both soil and hydroponic cannabis grow systems. We’ll also provide some tips on how to increase oxygen levels in the root zone which generally helps bring larger yields.
The root system of your cannabis plant is where all the essential nutrients are absorbed and transported throughout the plant. This is why it’s so important to focus on promoting and maintaining a healthy root system whether you use a soil-based root system or a hydroponic setup. When the root system is healthy, the rest of the plant will be healthy too.
There are a few key aspects that you should focus on in order to promote and maintain a healthy root system for your cannabis plant:
Soil: In a soil-based root system, you want to make sure that your soil is loose and aerated. The roots need oxygen in order to grow, so compacted soil will suffocate the roots and may lead to problems such as smaller yields or even root rot.
Hydroponics: In a hydroponic system, you need to make sure that the roots are receiving enough oxygen. One way to do this is by using an air pump and bubbler. The air pump will provide oxygen to the roots, and the bubbler will help circulate it throughout the system.
Oxygen: Did you know that the roots of your cannabis plants need oxygen in order to grow too? In fact, one of the most important aspects of root health is ensuring that the roots have access to oxygen. One way to increase oxygen levels in the root zone is by using a product called an “air stone.” Air stones are placed in the bottom of the grow container and emit small bubbles of oxygen that help aerate the roots.
Temperature: In a soil-based system, the roots need to be kept at a temperature between 60-70 degrees Fahrenheit. If the roots get too cold, they will go into shock and die.
Aside from the elements above, growers may incorporate additional nutrients into a soil-based system that could play a positive role in root health. The nutrients needed for strong root development are generally present in a good blooming fertilizer. In the clone and early growth phases, many horticulturists prefer to use a blooming base fertilizer. The two most important nutrient additives for root development are phosphorus and potassium.
In general, make sure to water your plants adequately, but don’t overwater them. Use a good quality soil or hydroponic growing medium and add organic matter to your soil, where applicable, to help improve drainage and aeration. The foundation of any plant is its root system so the care and attention paid to any crop should start there. By focusing on these key aspects of root health, you can promote a healthy root system that will lead to bigger, healthier buds and larger, more potent yields.
