PK 13-14 from BIONOVA, 1-liter bottle for home cannabis self-cultivation. Fertilizer used in technical horticulture to improve the development and production of plants during the flowering phase. PK 13-14 is a combination of essential nutrients, specifically phosphorus (P) and potassium (K), in a balanced ratio.
Phosphorus (P) is a macronutrient that plays a fundamental role in root development, energy production, and the overall growth of plants. It is also essential for the formation of flowers and fruits.
Potassium (K), another macronutrient, contributes to plant development, improves stress resistance, and promotes the quality of flowers and fruits. It also plays an important role in regulating the opening and closing of stomata, which affects nutrient absorption.
The PK 13-14 ratio indicates that it contains a higher concentration of potassium (K) compared to phosphorus (P), which favors optimal development of flowers and fruits.

To use PK 13-14 from Bionova, it is recommended to start its application from the second week of cultivation. At this stage, an initial dose of 0.5 ml of PK 13-14 per liter of water should be diluted. It is important to note that the irrigation method is used yes, irrigation no on soil, using the reservoir in NFT, Hydro or Coco.
As the crop progresses and reaches the fourth week, the dose of PK 13-14 is increased to 1 ml per liter of water.
This dose will be maintained until the end of the crop.
However, it is important to mention that the maximum recommended dose can reach 1.25 ml per liter of water.
13% water-soluble phosphoric anhydride.
14% water-soluble potassium oxide.

PK 13-14 is a fertilizer designed to be used in the last weeks of cultivation, specifically during the stage when the buds are forming and growing.
The high concentration of phosphorus (P) and potassium (K) in PK 13-14 plays a crucial role in the fattening of the buds and the production of heavier and larger flowers. These essential nutrients provide plants with the necessary elements to promote optimal bud development, resulting in a more productive and higher quality harvest.
PK 13-14 from BIONOVA works by providing plants with a balanced and concentrated combination of phosphorus (P) and potassium (K) during the flowering and fruiting stage. These two macronutrients play key roles in the metabolism and development of plants, especially during the formation of flowers and fruits.
The phosphorus (P) in PK 13-14 stimulates the development of a healthy and robust root system. It helps the plant absorb and efficiently use other nutrients, promoting vigorous growth. In addition, phosphorus is essential for the synthesis of ATP (adenosine triphosphate), a key energy molecule in the metabolic processes of plants. During the flowering phase, phosphorus contributes to the formation of larger and more abundant flowers.
To correctly apply PK 13-14 from BIONOVA, follow these general instructions:
Prepare a nutrient solution: Mix quality irrigation water with the base fertilizers and adjust the pH of the solution according to BIONOVA's recommendations. Make sure to completely dissolve the fertilizers before proceeding.
Start in the second week of the flowering phase: Start applying PK 13-14 from the second week of the flowering stage of your plants.
Initial dosage: In the second week of flowering, add 0.5 ml of PK 13-14 per liter of water in your nutrient solution. Mix the solution well for an even distribution of nutrients.
Increase the dose in the fourth week: As you move towards the fourth week of the flowering phase, increase the dose of PK 13-14 to 1 ml per liter of water. Continue mixing the solution well before application.
Maintain the dose until the end of the crop: From the fourth week and until the end of the crop, continue applying 1 ml of PK 13-14 per liter of water in your nutrient solution. Do not exceed the maximum recommended dose of 1.25 ml per liter of water.
Application in irrigation yes, irrigation no: BIONOVA recommends using the irrigation yes, irrigation no method on soil, using the reservoir in NFT, Hydro or Coco. Be sure to adjust the frequency and duration of irrigation according to the needs of your plants and the growing medium.
Observe and adjust: Regularly monitor the condition of the plants and observe their response to the application of PK 13-14. If necessary, adjust the doses according to the individual needs of your plants, but avoid overfeeding them.
