The Importance of Root Health in Cannabis Growth

Cannabis roots are a crucial part of the plants growing process. They are responsible for absorbing nutrients and water from the soil.

Roots also condition the rhizosphere by secreting compounds and antibiotics that improve the microbial environment. This symbiotic relationship helps protect the roots from damage, increases plant capacity to absorb nutrients and ultimately stimulates expansive root growth.


The temperature of your grow room plays a huge role in how your cannabis plants grow. It affects the rate of internodal growth, water absorption, respiration and PH level of the growing medium. It can also affect the colour of your buds and leaves.

The ideal temperature range for vegetative growth is 20degC to 28degC during the day and 68degF to 82degF at night. These temperatures support a low-stress environment and provide your plant with the energy it needs to promote robust leaf and stem development.

Your grow room’s temperature can be controlled by a temperature control system, which helps to maintain an ideal climate throughout the growing cycle of your plant. This can be done by using an environmental controller that heats or cools the soil and roots of your plants.

Temperature has a significant impact on nutrient availability to your cannabis plants, which is why it’s important to keep it at the right temperature. Too much or too little can lead to nutrient deficiencies that will stunt your plants’ progress and reduce their yields.

While most growers know that pH and EC levels are crucial when it comes to their plants’ root health, many fail to realize how much importance temperature plays in the overall development of their roots. This is why it’s so important to always check the temperature of your water before watering your plants.

In addition to temperature, your plants’ roots are affected by the humidity in your grow room. High levels of humidity can suppress the development of your plants’ roots, and lower humidity can encourage it.

If you’re growing indoors, the ideal temperature for your grow room is around 18degC to 24degC during the day and 59degF to 64degF at night. This is the perfect range for promoting robust leaf and stem development, as well as optimal nutrient absorption.

Colder temperatures can negatively impact your plants’ root development, as well as their nutrient absorption. The most obvious symptom of this is that your plants’ roots will stop growing entirely, and they won’t be able to absorb nutrients like phosphorus, which can lead to a drastic reduction in your yields.


Water is one of the most vital factors in growing cannabis. This is because it contains a range of nutrients and bacteria that cannabis plants need to grow healthy and strong.

The type of water you use also has an effect on cannabis growth. Some bottled and tap water contain chemicals such as chlorine that can hurt your plant in various ways, while other water is naturally rich in minerals like calcium and magnesium which are needed by cannabis plants for their growth.

In addition to water, other factors also impact cannabis growth such as temperature and pH levels. Temperatures that are too cold or too hot can shock a plant’s roots and cause a variety of symptoms including drooping, wilting, stunted growth and yellowing leaves. Heat can also attract pests and pathogens into the grow room that can infect your plants.

Similarly, the pH level of your water can have an impact on a plant’s ability to absorb nutrients. Maintaining the pH of your water at a neutral range is important, as this will help you avoid nutrient burn and other problems that could result in lower yields for your plants.

Another way to ensure your water is clean and safe for your cannabis plants is to run a comprehensive water report on your water supply. This is an easy and cost-effective way to make sure your water has no harmful bacteria in it.

Water is an essential element of all life on Earth, and without it there would be no life. In fact, all plants, including cannabis, consist of around 80% water.

The molecular structure of water is simple. Two hydrogen atoms bond with one oxygen atom, creating an asymmetrical molecule with positive and negative charges on either side (Figure 1). The charge difference is known as polarity and determines how water interacts with other molecules.

Roots need a lot of water to thrive, so it is important to provide your plants with enough water for their needs while not overwatering them. This is especially true for soil environments where it is often more difficult to judge when the plant needs more or less water.


The roots of plants are where the majority of their water and nutrients are absorbed. The health of these roots determines how the rest of your crop grows and performs. They also help to maintain a healthy pH balance and reduce salinity.

In addition, a healthy root system is essential for maintaining proper air flow within the grow medium. This is crucial for nutrient delivery, which is a key factor in the development of terpenes and cannabinoid content.

As the plant continues to grow, it requires additional nutrients in the form of calcium and magnesium, which are both found in the soil and in fertilizers. The cannabis plant can also use these nutrients to develop stronger cell walls, which helps the plant survive and thrive.

Another factor is light intensity, which can affect the development of a cannabis plant. A grower may want to increase the lighting level to optimize plant growth and maximize yields, but they should be careful not to overdo it.

Most growers choose a 24/0 or 18/6 light cycle to give their plants the ideal amount of daylight to produce large, high-quality buds. They also have to be mindful of storing the plant and its lights away from windows, which can attract insects and other pests.

In order to avoid this, many indoor growers have begun using LED lights in their growing space. These energy-efficient lights have become increasingly popular among growers due to their long lifespan and low electricity costs.


Soil is an essential component of every plant, and cannabis plants are no different. A healthy soil will help the roots of your plant thrive, and that in turn will yield strong plants with big buds.

Soils have a wide range of properties that will determine its ability to provide the right environment for cannabis growth. Some soils can be very heavy or clay-like, while others are more loose and sandy. Soils can also vary in color from sand to black clays and are usually classified based on their size of mineral particles.

A soils ability to hold water, air and nutrients is a major factor in its fertility. It is important to have a soil that can hold enough water and has good air drainage, as these characteristics will determine its ability to support the root system of your cannabis plant.

Another important factor in a soils fertility is its micronutrient content. This is the amount of minerals such as calcium, iron, phosphorus and potassium that your plant will need to grow strong.

The microbes in the soil will have a direct impact on your plant’s nutrient needs. They are able to decompose dead organic matter, draw nitrogen from the air to feed your plants and perform many other beneficial functions.

In addition, they have a role in the production of many compounds, including cannabinoids. Consequently, the more diverse the microbes in your soil are, the better they will perform their jobs and the healthier your cannabis plants will be.

Regardless of whether you use living or synthetic soil, it is important to maintain a balanced ecosystem that will allow your cannabis plants to thrive. This means adding soil amendments and inoculants that contain fungi, bacteria, insects and other microlife to your growing space.

By adding a base soil and incorporating the right amendments, inoculants and other additives into your growing space, you can achieve the ideal balance for your cannabis plants. This balance will allow them to access all of the nutrients they need when they need them, without the use of harsh pesticides and herbicides that can be harmful to your plants and the planet.
