GreenPlanet PK Spike – Highly concentrated PK booster for maximum flowering

GreenPlanet PK Spike has been developed to provide your flowering plants with a steady supply of phosphorus (P) and potassium (K). With over 25% more P/K than the leading competitor, this flowering stimulator ensures vigorous plants, stronger cell structures and impressive yields. Even at a dosage of only 1.0 ml/L, PK Spike can give your plants a nutrient boost of up to 250 ppm.

Advantages of PK Spike

• Promotes flower formation and seed production
• Ensures even and earlier ripening
• Improves the quality and density of the harvest
• Supports cell wall strength – less risk of broken stems and branches
• Prevents phosphorus and potassium deficiency symptoms
• Strengthens the plant's defences against diseases and pests

How PK Spike works

• Phosphorus (P) is essential for energy transfer, photosynthesis and nutrient uptake – all factors that ensure large and vigorous flowers.
• Potassium (K) efficiently converts phosphorus into energy, strengthens cell walls and ensures compact, firm flowers instead of airy inflorescences.
• The combination of P & K gives your plants exactly the boost they need during the flowering phase – for more yield, density and quality.

Application & dosage

• Dosage: 0.5 – 1.0 ml/L nutrient solution
• Application: From the 2nd week of flowering every 2 weeks until one week before flushing
• Up to 250 ppm boost – adjust the nutrient strength accordingly
