If you want the highest quality fruits and flowers, CANNA PK 13/14 is the right product for you. CANNA PK 13/14 is a mixture of top quality nutritional minerals that are required during flowering. It's easy to use and can support high yields. If you add PK 13/14 at the right moment, you will get astonishing results! PK 13/14 is suitable for any growing medium. Pure elements to encourage flowering CANNA PK 13/14 is a high grade mixture of phosphorus and potassium that is added during the flowering phase. Both elements play a big role during the generative phase of plants. Thanks to a special production process CANNA has succeeded in combining pure phosphorous and potassium in very high concentrations. This makes PK 13/14 available to the plant quickly and directly. Phosphorous (P) is a macro nutritional element for every plant. It plays a key role in metabolism and energy transfer. In the flowering phase, extra phosphorous is needed. Phosphorous is required for proper cell formation, among other things. Potassium (K) is also a macro nutritional element. It is found throughout the plant and is necessary for a lot of its activities. It is essential for transporting water and nutrition (sieve vessels) and it is responsible for the plant’s quality and rigidity. In addition to this, it controls countless other processes such as sugar production. Potassium ensures that the plant can produce enough sugars during flowering, which are essential for the development of the flowers. Perfect combination with CANNABOOST There comes a moment during the plant’s development when the need for phosphorous and potassium increases greatly. If CANNA PK 13/14 is given at this moment you will satisfy the plant’s increased needs and the fruits are positioned to reach their full potential. CANNABOOST aids in plant processes and has a strengthening effect on PK 13/14. This perfect combination helps the plant to produce quality flowers. Suitable for every medium PK 13/14 is used with every medium and consequently it is used for cultivation in soil, in recirculating systems, when cultivating in coco and in run-to-waste systems. PK 13/14 is suitable for use when cultivating both indoors and outdoors. NPK Ratio When CANNA introduced PK 13/14, it used the standard European way to state the NPK ratio. This was expressing percentages of the nutrients in fertilizer as volume/volume (milliliters/ liter). Nowadays, the North American convention of using Mass/mass (milligrams/ kilograms) is the standard and mandatory way to state the NPK ratio's. Therefore CANNA was required to state the mass percentages of the contents of PK, thus the additional numbers 0 - 10 - 11. Same fine product, just a different way of stating the percentages of the nutrients, as 0 - 10 - 11 in mass percentages is exactly the same as 0 - 13 - 14 in volume percentages. Directions for use The nutrients potassium and phosphate are indispensable for plants during their flowering period. PK 13/14 is a venerable potassium - phosphate mixture. PK 13/14 dissolves well and is therefore easily absorbable. Shake the bottle well before use Add PK 13/14 once to a full nutrition tank Dosage: 0.2 fl oz/Gal (15 ml/10L) Use for approximately one week only Store in a dark place, away from extremes of hot and cold
