Ionic PK Boost (PK 14/15) is a high-strength flowering booster designed to support heavier flowering, stronger fruit development and improved bloom performance during the most demanding stage of the plant's life cycle. Formulated with a concentrated blend of phosphorus and potassium, Ionic PK Boost helps plants push energy into flower production when it matters most. Used alongside your regular Ionic Bloom nutrient, it helps support bigger flowers, improved density and stronger overall flowering performance. With an NPK of 0-14-15, this is a serious PK additive built for growers who want to maximise bloom potential without overcomplicating their feeding schedule. Product Type PK flowering booster NPK 0-14-15 Recommended Dose 1ml per litre Use Stage Flowering and fruiting Suitable For Soil, coco and hydroponics Compatible With All Ionic Bloom nutrients What Does PK Boost Do? During flowering, plants demand significantly higher levels of phosphorus and potassium to support flower formation, energy transfer and structural development. Ionic PK Boost delivers those key nutrients in a concentrated, plant-available form to help support aggressive blooming and maximise flowering performance during the critical production window. Used correctly, PK boosters can help improve: Flower size and density Fruit and flower production Plant energy during peak bloom Overall flowering performance Final yield potential Designed For Serious Flowering Performance Ionic PK Boost is quite a powerful bloom additive, which is exactly why growers rate it. It is designed to complement the Ionic Bloom nutrient range without needing massive feeding rates or complicated schedules. Because it is already highly concentrated, it should not be combined with other PK boosters or used above the recommended dosage. More PK does not automatically mean more flowers. Overfeeding during bloom is one of the easiest ways to stress plants and reduce performance. Keep it simple. Use it properly and let the formulation do the work. How To Use Ionic PK Boost Ionic PK Boost can be used from the first signs of flowering or fruit formation right through until the flush period. Growing Method Recommended Use Soil and Coco Use once per week at 1ml/L alongside your Ionic Bloom nutrient. Adjust EC to 1.5 (CF15). Hydroponics Add at 1ml/L to your reservoir and adjust EC to 2.0 (CF20). Replace nutrient solution weekly. If required, adjust pH after mixing nutrients. Always add nutrients and additives to water one at a time, stirring thoroughly between additions. Never mix concentrated nutrients together directly from the bottle. Why Growers Use PK Boosters Once plants enter heavy flowering, demand for phosphorus and potassium increases dramatically. Base nutrients alone can sometimes struggle to fully satisfy that increased demand, especially in fast-growing, high-yield environments. That is where a dedicated PK additive comes in. Ionic PK Boost helps bridge that gap, giving plants extra support during peak bloom without completely changing your feeding programme. Key Benefits Powerful PK 14/15 flowering booster Supports larger, denser flowers Designed for use during flowering and fruiting Suitable for soil, coco and hydroponics Works alongside all Ionic Bloom nutrients Easy one-part additive at just 1ml/L Helps support stronger bloom performance and final yields Highly concentrated professional-grade formula Why Buy From The Hydro Bros? The Hydro Bros stock Ionic PK Boost because it is a straightforward, proven flowering additive that does exactly what growers want it to do. If your plants are entering peak bloom and you want extra flowering support without unnecessary complexity, this is a proper solid PK option.
