Here’s What Could be Affecting Cannabis Plant Growth

Cannabis plants have immense potential for a variety of applications, from medicinal to recreational. However, for any of these applications to be a success, proper care must be taken during the growth process. But at times, there are unforeseen factors that can disrupt the natural growth of a cannabis plant. Here are some of the common culprits that could be affecting plant growth.

Nutrition

The nutrient composition of a cannabis plant is one of the most important influences on growth. A lack of key essential nutrients such as phosphorus, nitrogen, and potassium in the soil can stunt the development of a cannabis plant. Additionally, soil pH can also have an effect, with plants preferring a slightly acidic soil pH, some 5.8-6.5 on average.

Light Exposure

Light plays an important role in the growth of a cannabis plant. Photosynthesis is used to turn light into energy which is then used to drive development. A cannabis plant needs the light between a certain range for 8-14 hours a day to ensure healthy growth. Too much or too little light exposure will have adverse effects on the growth of the plant.

Water

The water used in the growth of a cannabis plant also plays a significant role. Cannabis plants need a steady supply of sufficient water for growth. The amount of water needed will depend on the climate and stage of growth but cannabis plants generally need a lot of water for optimal growth. Too little water can make the leaves appear dry and withered, and too much can result in root rot.

Temperature and Humidity

Temperature and humidity affect a cannabis plant’s growth in a variety of ways. Temperature can directly affect the rate of photosynthesis, while humidity can affect the rate at which water is absorbed. Generally, cannabis plants prefer temperatures between 70 and 80 degrees Fahrenheit, with a relative humidity of around 40-50%. Too much or too little of either of these parameters can have negative effects on the growth of the plant.

Air Flow

Adequate air flow is an important factor in the growth of a cannabis plant. Poor air flow can result in the accumulation of varying levels of carbon dioxide in the air around the cannabis plant, which can cause the leaves to dry and wilt. Good air flow helps to circulate the CO2 around the plant, allowing for more efficient photosynthesis.

Pest and Disease

Pests and diseases can easily attack and significantly stunt the growth of a cannabis plant. These could be caused by a variety of reasons, such as a lack of nutrients, unsuitable humidity levels, or even improper air flow. Proper pest and disease management is crucial for successful and healthy growth of a cannabis plant.

Nutrient Uptake

Nutrients are needed for the growth of a cannabis plant, but these nutrients must be absorbed in the right amounts for successful growth. If the soil is too acidic or basic, then nutrients will not be absorbed efficiently, resulting in nutrient deficiencies. Additionally, poor aeration in the soil can reduce the amount of oxygen that is available for the roots to uptake nutrients, therefore reducing the overall growth of the cannabis plant.

Seed Quality

The quality of the seed can also play an important role in successful cannabis growth. Low-quality seeds are more prone to diseases, pests, and other abnormalities that can decrease the overall health and growth of the cannabis plant. Therefore, it is important to be sure to use high-quality seeds to maximise the growth of the plant.

Environmental Factors

Environmental factors such as wind, rain, and drought can also affect the growth of a cannabis plant. A right balance between these environmental factors is important to ensure optimal growth. Too much or too little of any of these factors can have adverse effects on the development of the cannabis plant.

Soil Quality

The quality of the soil used for cannabis cultivation is crucial for successful and healthy growth. The soil must have good aeration and be able to hold the right amount of water. Additionally, the soil should also be of the right pH and contain the right amount of essential nutrients for optimal growth.
