The cultivation of cannabis Indoors has become a popular choice due to legal restrictions, climate or privacy. Although growing indoors presents its own challenges, if done correctly, it can result in high quality harvests. In this post, we'll discover how to grow and care for cannabis plants indoors.

What does the cannabis plant need to grow?

The cannabisLike any other plant, it has basic needs that must be met in order to achieve healthy growth:


Cannabis plants require a lot of light for photosynthesis. When growing indoors, LED, HPS (High Pressure Sodium) or CFL (Compact Fluorescent Light) lights can be used. The advantage of LED lights is that they consume less energy and emit less heat.


The frequency of watering will depend on the size of the plant, the type of substrate and the ambient humidity. It is essential not to overwater, as excess moisture can cause fungus and disease.


The cannabis can be grown in soil or in hydroponic systems. If you choose soil, an aerated, well-drained mix is recommended. Hydroponic systems allow more precise control of nutrients but can be more complex for beginners.


Cannabis plants need essential nutrients to grow. In vegetative stages, they require more nitrogen, while in the flowering stage they will need more phosphorus and potassium.

Temperature and Humidity

The cannabis prefers temperatures between 20°C and 28°C. Relative humidity should be between 40-60%. During the flowering stage, reducing humidity can help prevent mildew problems.

How to get the highest production indoors?

Maximizing production requires constant attention and adjustments:

Plant Training

Techniques such as LST (Low Stress Training) or topping can help the plant develop more main tails and improve light distribution.


Increasing the level of CO2 in the environment can enhance growth, but it is essential to ensure that there is sufficient ventilation.

Pest and disease control

It is vital to regularly inspect plants for signs of pests such as spider mites or diseases such as mildew. Early prevention can save a crop.

Choosing productive strains

Some varieties of cannabis have a higher yield potential than others. Researching and choosing strains known for high yields can be beneficial.

How to put into bloom indoors?

Cannabis is a photoperiodic plant, which means that its flowering cycle is influenced by light. Indoors, the grower has total control over this aspect.

Change of photoperiod

To induce flowering, it is necessary to adjust the lights so that the plant receives 12 hours of uninterrupted light and 12 hours of uninterrupted darkness. This change simulates autumn conditions, when the days become shorter.

Control temperature and humidity

As mentioned above, it is beneficial to reduce humidity during flowering.

Adequate nutrition

At this stage, the plant needs more phosphorus and potassium. It is essential to adjust feeding to meet these needs.

Avoiding stress

Any form of stress, such as sudden temperature changes or interruptions in the dark cycle, can affect the quality and quantity of flowering.

Cultivate cannabis Indoor growing requires a combination of knowledge, patience and attention to detail. By providing the right conditions and being attentive to the plant's needs, you can achieve high quality harvests in the comfort of your home. Good luck and happy growing!
