DutchGrow PK13/14: For Large, Heavy Fruits

Do you want to provide your plants with the right nutrients to produce large and heavy fruits? DutchGrow PK13/14 is a high-quality phosphorus-potassium blend that stimulates flowering and fruit formation. With this user-friendly additive, you enhance both the quantity and quality of your harvest.

Why DutchGrow PK13/14?

This blend of phosphorus and potassium is developed for use during the flowering phase because both elements are essential in the generative phase of plants:

  • Phosphorus (P): Plays a key role in metabolism and energy transfer. Extra phosphorus is needed during the flowering phase as it strengthens cell formation in flowers.
  • Kalium (K): Essential for the transport of water and nutrients, the quality and stiffness of the plant, and crucial for sugar production, which is important for the development of flowers.

Benefits of DutchGrow PK13/14:

  1. Pure Elements for Bloom Stimulation: Through a special production process, pure phosphorus and potassium are available in high concentrations, which can be quickly absorbed by the plant.
  2. Perfect Combination with DutchGrow XL: Use XL along with PK13/14 for the best blooming results. XL improves metabolism and strengthens the effect of PK13/14.
  3. Suitable for Any Medium: Whether you are growing in soil, coco, recirculation systems, or run-to-waste systems, PK13/14 fits perfectly.

Choose DutchGrow PK13/14 for lush blooming and an abundant harvest. See how your crops flourish with the perfect balance of phosphorus and potassium.
