Cannabis plants can grow to be quite tall, sometimes reaching heights of over six feet. However, the height of a plant is determined by many factors, including the strain of cannabis, the growing conditions, and the amount of time the plant is allowed to grow.

Indoor vs. Outdoor
The average height of a cannabis plant is between 3 and 6 feet. However, the plant can grow taller than 20 feet in some cases. The tallest recorded cannabis plant was 22 feet tall.
The height of a cannabis plant is determined by several factors, including the strain of the plant, the growing conditions, and the amount of time the plant is allowed to grow.
Indoor plants tend to be shorter than outdoor plants because they are usually grown in smaller spaces and do not have as much room to grow. Outdoor plants can grow taller because they have more space and can receive more sunlight.
Cannabis plants can be trimmed to control their height. Trimming also helps the plant to produce more buds.
Soil
Cannabis plants can range in height depending on the strain, but also on whether they are grown in soil or hydroponically. In soil, plants tend to grow taller and faster due to the abundance of nutrients available. Plants grown hydroponically are generally smaller because they are grown in a controlled environment with less nutrient variation.
Indica strains tend to grow shorter and bushier than sativa strains, which tend to be taller and lankier. However, there is considerable variation within each strain, so these are only generalisations.
The main thing that determines how tall your cannabis plant will grow is the size of the pot you are growing it in. A larger pot will allow the roots to spread out and the plant to grow taller. If you are limited on space, you can always try topping or training your plant to encourage it to grow horizontally rather than vertically.
Nutrients
One of the main things that will impact how tall your cannabis plants grow is the availability of nutrients. If your plants are well-fed, they will be able to reach their full potential height. Make sure you are using a high-quality nutrient solution and that your plants are getting the right mix of nutrients for their stage of growth.
Another important factor to consider is the light source you are using. Plants need light to grow, and if they are not getting enough light, they will not reach their full height potential. Make sure you are providing your plants with enough light, either from the sun or from artificial lighting.
Finally, temperature can also play a role in how tall your cannabis plants grow. If it is too cold, the plants will not be able to grow as much. Make sure the temperature in your grow room is warm enough for your plants to thrive.
Lighting
The height of a cannabis plant is determined largely by the type of light it is grown under. Indoor growers often choose to grow under artificial lights, which can be placed closer to the plants, resulting in shorter plants. Outdoor growers, on the other hand, rely on natural sunlight, which promotes taller growth. The intensity of the light also plays a role in determining plant height – brighter light tends to produce taller plants.
Temperature
One of the key environmental conditions that will affect how tall your cannabis plants grow is temperature. If the temperature is too hot, then your plants will experience what’s called “heat stress.” This can cause them to stop growing entirely, or to remain stunted in their growth. The ideal temperature for cannabis growth is between 70- and 85-degrees Fahrenheit. If you can keep your grow room within this range, then you’ll be more likely to see your plants reach their full potential in terms of height.
Humidity
Relative humidity (RH) measures the amount of water vapor in the air. The ideal RH for cannabis growth is between 40 and 60 percent. If the RH is too low, plants will transpire more water than they can absorb, leading to stress and potential dehydration. If the RH is too high, moisture will build up on plant surfaces, encouraging mold growth.
Pruning
Pruning is the process of removing branches, leaves, or stems from a plant. It can be done for aesthetic reasons, to improve yields, or to encourage the growth of certain parts of the plant.
Cannabis plants can be pruned in a number of ways, including topping, FIMing, LSTing, and defoliation. Topping is the process of cutting off the main stem of the plant to promote lateral (side) growth. FIMing (or “FIM”ing) involves cutting off the top quarter of a plant’s main stem, which encourages the growth of multiple new tops. LSTing (or “LST”ing) stands for “low stress training” and involves gently bending and securing stems to encourage the plant to grow horizontally. Defoliation is the process of removing leaves from the plant, which can be done for aesthetic reasons or to encourage bud development.
Pruning has a number of benefits for cannabis plants. It can increase yields by promoting more even growth and increasing light exposure and air circulation to the buds. It can also improve the quality of your buds by increasing resin production and terpene content. When done properly, pruning can also help your plants better withstand pests and diseases.
