The fertilization process for automatic marijuana plants is essential to ensure healthy growth and an abundant harvest. Here are some tips on how to fertilize your autoflowering plants:

Properly fertilizing your autoflowering plants is crucial for their development. Start using a balanced fertilizer from the beginning of their life cycle, as these plants automatically bloom after a few weeks of vegetative growth.

Use specific fertilizers for autoflowering, as they contain the right nutrients in the correct proportions.

When to Start Fertilizing Autoflowering Plants

The right time to start fertilizing your autoflowering plants is crucial for their development. In general, you can start fertilizing these plants when they are 2 to 4 weeks old, depending on the amount of food contained in the substrate you use. During the first weeks, they may get enough nutrients from their initial substrate, but after that period, they will need nutritional supplements.

How Often to Fertilize Autoflowering Plants

The frequency of fertilization for autoflowering plants can vary depending on the type of substrate you use and the specific fertilizer you apply. In general, it is recommended to fertilize these plants every 2 or 3 waterings. However, it is essential to observe the signals the plant gives you, such as the color of the leaves and their growth, to adjust the frequency according to their individual needs.

Soil for Autoflowering Plants

When it comes to growing autoflowering plants, choosing the right soil is a crucial factor. Unlike photoperiodic varieties, autoflowering plants have a shorter life cycle and a limited growth period. Therefore, you need soil that provides them with the necessary nutrients from the beginning and allows them to develop optimally.

One of the advantages of autoflowering plants is that they can be grown both indoors and outdoors, which means you should consider different soil options depending on your growing conditions. Below, we will provide you with detailed information on how many liters of soil you need, the best soils for autoflowering plants, and the ideal kits for outdoor cultivation.

How Many Liters of Soil Does an Autoflowering Plant Need?

A common question among growers is how many liters of soil are necessary for an autoflowering marijuana plant. The answer largely depends on the variety and the final size you want for your plants. However, as a general rule, a minimum of 7 to 11 liters of soil per plant is recommended for autoflowering plants.

It is important to remember that, unlike photoperiodic varieties, autoflowering plants do not have time to develop extensive roots. Therefore, a larger container is not always better. An appropriate pot size will provide the necessary space for growth and prevent the waste of soil and resources.

Best Soil for Autoflowering Plants

Choosing the right soil is essential for the success of your autoflowering plant cultivation. Fortunately, there are several high-quality options on the market specifically designed to meet the needs of these plants.

Cannabiogen Auto Mix 2.0

Cannabiogen's Auto Mix 2.0 is a high-quality soil specifically designed for the cultivation of autoflowering plants. This premium soil has been carefully blended to provide your plants with everything they need from the beginning to the end of their life cycle. Cannabiogen's soil is an exceptional choice for autoflowering growers who want to simplify their cultivation process without compromising the quality of their harvests.

One of the standout features of Auto Mix 2.0 is its excellent water retention capacity, ensuring that your plants have constant access to the necessary hydration. At the same time, this soil provides adequate aeration to the roots, promoting root development and efficient nutrient absorption. Auto Mix 2.0 has been enriched with the essential nutrients your autoflowering plants need, which means that it is not necessary to apply additional fertilizers for much of their life cycle.

Soil for Outdoor Autoflowering Plants

Growing autoflowering plants outdoors offers the opportunity to make the most of natural sunlight and allow your plants to grow in an environment closer to their natural habitat. However, it is essential to choose the right soil to ensure the success of your outdoor cultivation.

Outdoor Autoflowering Kit with Soil

If you are looking for a complete and convenient solution for growing autoflowering plants outdoors, kits specifically designed for this purpose are an excellent option. These kits usually include everything needed for your plants to grow healthily and produce abundant harvests in your garden or terrace.

One of the outdoor autoflowering kits includes quality soil, suitable pots, and of course, autoflowering seeds selected for their resilience and performance. By choosing one of these kits, you can simplify your cultivation process and have the confidence that you have the essential elements for success.

Pots for Autoflowering Plants

When it comes to growing autoflowering plants, choosing the right pot plays a crucial role in their development and yield. The right pots provide space for the roots to expand, ensure good drainage, and allow the plants to obtain the nutrients and oxygen they need to thrive.

Which Pot to Plant Autoflowering Plants In?

Choosing the pot for your autoflowering plants can make a difference in your harvests. First of all, you have to decide if you want the pot for growing autoflowering plants outdoors or indoors, as outdoors it is better to choose pots with greater capacity. Another issue is the final size of the plant you want to obtain, because limiting the volume of the pot also limits the growth of the plants.

Pots for Outdoor Autoflowering Plants

When growing autoflowering plants outdoors, you must select pots that adapt to outdoor conditions. Choosing the right pot for growing autoflowering plants outdoors can influence the resilience of your plants and their ability to take advantage of natural light.

20-Liter Pot for Autoflowering Plant

A 20-liter pot is an excellent choice for growing autoflowering plants outdoors. These pots offer enough space for root growth and allow the plants to reach their full potential. In addition, their capacity to retain water and nutrients is ideal for the changing conditions of outdoor cultivation.

Pots for Indoor Autoflowering Plants

Growing autoflowering plants indoors offers total control over the environment, but it also requires careful selection of pots. Pots for indoor use must be compatible with the size of your growing space and ensure good airflow and drainage.

7-Liter Pot for Autoflowering Plant

A 7-liter pot is a popular choice for growing autoflowering plants indoors. These pots are large enough for the roots to have space to grow, but they won't take up too much space in your growing area. Their water retention capacity and ease of handling make them a solid choice for indoor cultivation.

Autoflower nutrients

Autoflowering plants have some different characteristics compared to photoperiodic plants, and this also applies to their nutritional needs.

They can handle similar nutrient levels to photoperiod plants, but require a more constant and balanced supply due to their short lifespan.
