Growing cannabis indoors has gained popularity in recent years, especially in places where legality allows it. This process not only gives you the advantage of having complete control over the growing environment, but also allows for a constant supply of the plant. However, there are essential details to consider to ensure your plants thrive. Below, we present the most relevant aspects.
What does the cannabis plant need to grow?
Cannabis, like any other plant, has basic needs that must be met for it to grow healthily:
-
Light
Cannabis plants require an abundant amount of light to grow properly. LED or HID lights (such as high-pressure sodium) are ideal for indoor growing.
-
Water
Although cannabis needs water to grow, it is essential not to overwater. Too much water can lead to diseases such as root rot.
-
Nutrients
Cannabis plants require different nutrients at different stages of growth. Generally, they will need more nitrogen during the vegetative phase and more phosphorus and potassium during flowering.
-
Fresh air
A constant flow of fresh air is vital for cannabis plants. Make sure you have a good ventilation system to keep the air circulating.
-
Soil
Fertile, well-aerated soil is essential for cannabis growth. Many growers opt for special cannabis substrates available in specialized stores.
How to get the highest production indoors?
Maximizing the production of your cannabis plants indoors requires attention and certain techniques:
-
Pruning
this technique consists of cutting the upper parts of the plant to make it grow bushier and with more branching.
-
SCROG (Screen of Green)
This is a technique that uses a mesh or screen to guide the horizontal growth of plants. This allows an even distribution of light, which leads to an increase in production.
-
Additional CO2
Increasing the amount of carbon dioxide can accelerate plant growth and increase yields. However, it is essential to do so with caution and knowledge.
-
Controlling temperature and humidity
Keeping these factors at ideal levels (temperature between 20-25°C and relative humidity of 50-60%) can optimize plant growth and yield.
How to start flowering indoors?
Indoor cannabis flowering is induced by the grower. Here are the steps to achieve it:
-
Change the light cycle
To induce flowering, it is necessary to adjust the lights to a cycle of 12 hours on and 12 hours off.
-
Use specific nutrients for flowering
As mentioned, at this stage, the plant needs more phosphorus and potassium. Be sure to provide adequate fertilizers.
-
Maintain a stable environment
During flowering, plants are more sensitive to changes in their environment. Keep the temperature and humidity at stable levels.
Growing cannabis indoors can be a rewarding experience if you take into account the basic needs of the plant and apply specific techniques to maximize production. Be sure to do your research and prepare properly for the best results. Happy growing!
