Ionic® PK Boost is a plant nutrient supplement specifically formulated to be applied during the final fewweeks before harvest of most fruiting and/or flowering crops. Ionic® PK Boost allows the grower easy control of the extra phosphorus and potassium that can lead to bumper yields. Ionic® PK Boost is designed to work with Ionic® Bloom and Ionic®Bloom Hardwater, but is also compatible with almost all liquid nutrients of the bloom variety. Ionic® PK Boost delivers the key mineral elements phosphorus (P) and potassium (K) in a pure form that is instantly accessible to the plant. These crucial ingredients are used in abundance by plants in their fruiting or flowering cycle and the extra levels provided by Ionic® PK Boost can lead to larger flowers and greatly increased fruit and vegetable yields. Ionic® PK Boost is also designed to replenish the mineral levels that are usually in short supply in hydroponic reservoirs. Ionic® PK Boost restores the missing elements that plants use during the fruiting and flowering cycle and restores an ideal balance in the reservoir for optimum plant performance.
