PK Heavy by Nutrifield 

PK Heavy is a refined synthetic phosphorous (P) and potassium (K) supplement to support the plant’s increased PK needs during the flowering phase. Phosphorous is a key building block of the plant’s energy molecule, ATP (adenosine tri-phosphate), which is required to support the elevated levels of metabolic activities during flowering, such as photosynthesis and respiration.

Potassium is involved in the movement of water and nutrients within the plant, and supports the increased requirements of the development of healthy flowering buds. The increased supply of phosphorous and potassium during flowering, supports the formation of additional flowering sites and promotes enhanced flower yield and quality.

 Phosphorous (P)

Nutrifield PK Heavy contains high levels of the macronutrient phosphorous (P), which is a key component of ATP, the chemical energy molecule in plants required to carry out metabolic activities.

Flowering is a very energy intensive cycle of plant growth, which places a high demand on phosphorous (P) to fulfil the increased ATP requirement. The boost in phosphorous (P) from PK Heavy stimulates flower bud development, bud set, and blooming.

 Potassium (K)

Nutrifield PK Heavy delivers high amounts of potassium (K) which facilitates the internal movement of nutrients through the plant.

Nutrients are required as they are the building blocks for flower formation. Potassium is critical for the efficient movement of nutrients within the plant to the flowering sites where they are needed. The boost in potassium (K) from PK Heavy ensures stomata function correctly to prevent water loss and ensure sufficient CO2 is available, as these are critical during photosynthesis.

Targeted PK Support for Heavy Flowering

Give flowering plants targeted nutritional support with Nutrifield PK Heavy, a concentrated phosphorus and potassium additive designed specifically for the early to mid flowering stage.

Highly available phosphorus supports energy transfer and cell division as plants transition into reproductive growth, while potassium helps move carbohydrates and nutrients towards developing flower sites. The formula also contains triacontanol to support photosynthetic efficiency and plant metabolism during this demanding stage.

Designed for use alongside your base nutrient programme, PK Heavy helps support faster, more uniform flower development, increased flower-site formation and improved early-stage density. It is suitable for hydroponic, coco and soil growing systems.

FAQs

Nutrifield PK Heavy is a concentrated flowering additive containing phosphorus, potassium and triacontanol. It is designed to support flower development and yield during the early to mid flowering stage.

PK Heavy is designed primarily for the early to mid flowering stage, when plants experience increased energy demands and begin developing flower sites.

Nutrifield's current application rate for early flowering is 0.5ml per litre of nutrient solution. Always follow the appropriate Nutrifield feed schedule for your growing system.

Phosphorus supports energy transfer and cell division, while potassium assists carbohydrate movement, enzyme activity and water regulation. Both play important roles as plants develop flowers.

Yes. PK Heavy contains triacontanol, a plant biostimulant included to support photosynthetic efficiency, metabolic activity and uniform flower development.

Yes. Nutrifield states that PK Heavy can be used across hydroponic, coco and soil growing systems as part of a suitable nutrient programme.
