VitaK Potassium Sulphate 25kg

Unlock Your Pot-tential with VitaK Potassium Sulphate 25kg

Potassium shortages during bloom can leave South African crops with small, soft buds, poor colour and reduced shelf life — especially in hydro systems or when high nitrogen pushes K uptake out of balance. VitaK Potassium Sulphate 25kg supplies a clean, chlorine-low source of 420 g/kg potassium and 180 g/kg sulphur in highly water-soluble white granules, delivering immediate availability without salinity stress or chloride toxicity. Sulphur supports protein synthesis and terpene production, enhancing flavour, aroma and overall quality in fruiting and flowering crops. Perfect for fertigation, hydroponics or foliar sprays (0.5% solution), it mixes cleanly at low temperatures (7.87 g/100g water at 0 °C) and helps maintain stable pH (5.90–6.20) in recirculating setups. Use as directed to hit 100–400 ppm K in nutrient solutions, adjusting for existing water content — ideal for tomatoes, peppers, strawberries or cannabis during heavy fruit-fill phases. Sustainable, high-purity correction and supplement that maximises yield, density and market value while minimising waste in water-conscious SA operations.

Key Features

• High potassium (420 g/kg) & sulphur (180 g/kg) – drives bloom density, fruit quality & terpene production
• Low chlorine (max 30 g/kg) – safe for long-term hydro & sensitive crops without salinity build-up
• Excellent water solubility – fast dissolution for fertigation, hydroponics & foliar applications
• Acid-neutral pH range – helps stabilise solutions in variable SA water sources
• White granular form – easy handling, uniform distribution & no clogging in drippers
• Versatile correction/supplement – ideal for K-deficient stages in open field or controlled environments
