PK 13-14 CANNA: the ideal stimulator to maximize bud fattening
PK 13-14 CANNA is a powerful flowering stimulator designed to boost bud fattening in the last weeks of cultivation. Its formula rich in phosphorus and potassium significantly contributes to increasing the size and density of the flowers, ensuring a more productive and resinous harvest.

PK 13-14 by CANNA is a fertilizer specifically for the flowering stage that provides an extra boost of phosphorus (P) and potassium (K), two essential nutrients for the optimal development of buds.
During the final stage of cultivation, when the flowers are already formed, this product acts as a true booster, helping plants develop a greater number of calyxes and fatten the buds, providing impressive consistency.
Both in indoor and outdoor crops, you will notice a difference in the density and weight of the fruits, resulting in a more abundant and resinous harvest.
PK 13-14 CANNA stands out for its ease of use, being compatible with a wide variety of substrates and irrigation systems.
Whether you grow in soil, coco or in hydroponic systems, this fertilizer is highly efficient when combined with a flowering base such as Terra Flores by CANNA, ensuring that the plant receives all the necessary nutrients in this crucial phase of cultivation.
It is essential to use PK 13-14 CANNA in moderation and according to the instructions, as over-fertilization can damage the plants. It is recommended to start with a dose of 0.5 ml per liter of water from the third week of flowering, when the flowers are already formed, and gradually increase up to 1.5 ml per liter over a period of two weeks. To maximize its effectiveness, it is ideal to use an EC meter and combine it with other products from the CANNA line, such as Canna Boost Accelerator, to achieve higher yields. PK 13-14 is used together with a flowering base, thus providing an adequate balance of essential nutrients.
PK 13-14 CANNA has a composition of:
These two elements are key for the production and fattening of buds, as phosphorus is essential for flower formation and potassium helps in the transport and assimilation of other nutrients necessary for optimal development.
The use of PK 13-14 CANNA in cannabis cultivation offers multiple benefits. Firstly, the additional phosphorus and potassium help plants make the most of their reserves during the final flowering stage, resulting in larger, more compact, and resinous buds. In addition, this product promotes the production of additional calyxes, which increase the density and weight of the fruits, resulting in greater productivity. For growers seeking quality buds and high yields in their harvests, PK 13-14 is an excellent option.
Another important benefit is its versatility, as PK 13-14 CANNA is compatible with any type of substrate and automated irrigation system, such as hydroponic systems. This makes it an accessible product for growers with different setups, from classic soil cultivation to more advanced systems like hydroponics or coco cultivation.
By combining PK 13-14 with other fertilizers from the CANNA range, such as Canna Terra Flores or Canna Coco A and B, results are optimized, achieving healthy plants and extraordinary buds. In addition, at the Grow Shop in Spain, you will find this product available with discreet shipping, ideal for growers who value privacy in self-cultivation of cannabis.
PK 13-14 CANNA is a fundamental ally for cannabis growers looking to boost bud development in the final phase of the cycle. Thanks to its high concentration of phosphorus and potassium, this stimulator ensures explosive growth and maximized flowering, achieving dense, tight, and very resinous buds.
