How to choose the best pot for growing marijuana? Everything you should consider  

Growing marijuana outdoors can be an exciting and rewarding experience. However, to ensure the success of your crop, it is essential to have the right equipment, and one of the most important elements to achieve this is the choice of the right pot. In this article, we will offer you a complete guide so that you can choose the best pot for growing marijuana outdoors and obtain an abundant and healthy harvest.

Characteristics to take into account when choosing a pot

Choosing the right pot is a crucial point for the success of outdoor marijuana growing. However, there is often a lack of knowledge about what a pot can bring to the crop, such as the size, the liters of pot and substrate needed, as well as the material of the pot. Here are some things to consider when choosing a pot for outdoor marijuana growing:

Pot size

Pot size is one of the most important aspects to consider. An inadequate pot can limit root growth and make it difficult for the plant to absorb nutrients and water. If the pot is too small, the roots will be restricted and the plant will have difficulty obtaining the necessary resources. On the other hand, if the pot is too large, substrate, water and fertilizers will be wasted. In addition, a longer spacing between waterings will be required, which is also not beneficial.

It is recommended to use a pot of at least 18 liters for the cultivation of a single plant. However, the size of the pot may vary depending on the desired size of the plant. In general, the following is suggested:

– Pots between 18 and 50 liters for small plants.

– Pots between 50 and 70 liters for medium size plants.

– Pots between 70 and 150 liters for large plants.

It is important to remember that as the size of the container increases, the roots will have more room to expand and the plant will grow more.

Type of pot

There are different types of pots available on the market, each with its advantages and disadvantages. Some of the most common materials are plastic, fabric, and aerated pots. Below, we will explain the characteristics of each:

– Plastic pots: these are the most popular for outdoor marijuana growing. They are economical, durable, lightweight and easy to clean. However, they retain more heat than other materials, which increases soil temperature and negatively affects plant growth.

– Fabric pots: are becoming increasingly popular for outdoor marijuana growing. They are economical, allow excellent water drainage and aeration of the roots, regulate the substrate temperature, are lightweight and are easy to transport and store. Moreover, they favor the growth and development of the roots, which translates into a higher yield of the plant.

– Aerated pots: their open design with multiple holes allows excellent aeration of the roots, which improves their health and stimulates their growth. However, they are more expensive than other pots and may require more frequent watering due to their high aeration. In addition, their durability can be affected by prolonged exposure to the sun.

– Cork or polystyrene pots: offer good thermal insulation that helps keep the roots at a constant and stable temperature. They are generally not as airy as fabric pots, which can lead to moisture accumulation. In addition, their price is higher and their availability of models and sizes is limited.

Pot shape

The shape of the pot is also a factor to consider. Generally, square or rectangular pots allow for better use of space and greater stability, while round pots improve root distribution by not having corners in their design. However, the most important thing is that the pot has a good base where the roots can expand and that its height and width are proportionate, which will also contribute to good stability.

Pot drainage

Another vital factor for plant health. Without drainage holes or with insufficient drainage, water will stagnate at the bottom of the pot, being highly deadly for the plant.

It is essential to make sure that the pot has good drainage holes. If the pot does not have them, additional holes can be made. It is also advisable to place stones or arlite at the base of the pot to improve drainage and keep the soil in good condition.

Pot color

The color of the pot also has an impact on the crop. Black plastic pots are more common in indoor cultivation, where the luno has a direct impact on the pot.

In outdoor cultivation, on the other hand, the sun can overheat black pots, damaging root growth. For this reason, it is recommended to use white plastic pots, as they repel heat.

Tips on the use of pots when growing marijuana outdoors

Here are some tips and best practices that will help you to use pots properly when growing marijuana:

– Try to use fabric pots, since they are the most recommended for outdoor marijuana growing thanks to their performance and low price.

– If you plan to use a large pot, it is better to start with a smaller one and transplant when necessary. This will make transport and watering easier, and you will save water and fertilizers.

– If you cannot change your current pots, you can protect them from the sun by using cardboard or corks to create a thermal barrier.

– If you have the possibility to grow marijuana in soil, this is an excellent option, as the roots will have unlimited space to expand.

– Use quality soil for your marijuana cultivation, usually the right soil contains a special mix that favors the development of marijuana plants.

– Add stones or clay at the base of the pot to improve drainage and create a heat shield between the soil and the bottom of the pot.

– Remember to water properly and make sure the pot has good drainage holes to avoid water stagnation.


Choosing the right pot is a key factor in the success of your outdoor marijuana growing.

Using the right pot will allow optimal root development and contribute to stronger, healthier and more productive plants. In addition, you will be contributing to reduce the use of plastic and promoting a more sustainable cultivation.
