PowerSi PK Synergy 250ml is a concentrated bloom-phase microbial enhancer designed to increase phosphorus and potassium availabilitytwo critical nutrients for flower formation, resin production, and overall yield. This smaller size is perfect for home growers or small-scale projects looking for high performance without bulk. Formulated with a proprietary microbial consortium including Bacillus megaterium, Frateuria aurantia, Pseudomonas putida, and Bacillus mucilaginosus, PK Synergy helps unlock bound nutrients in the soil or media, allowing plants to absorb more P & K when they need it most. This results in better root health, increased bud density, higher trichome output, and bigger yieldsall without synthetic additives. It's easy to use, highly effective, and fully compatible with any bloom nutrient program.
