Power Si PK Synergy, Microbial Bloom Additive for Phosphorus and Potassium Uptake, Promotes Dense Flower Stacking and Trichome Development, Compatible with All Grow Media and Nutrients, 250ml Bottle

Power Si PK Synergy is an advanced bloom-phase additive that uses microbial bloom support to help plants maximize their flowering potential without overloading them with salts. Formulated with high-potency Bacillus megaterium, Pseudomonas putida, Bacillus mucilaginosus, and Frateuria aurantia, this phosphorus-potassium supplement unlocks P and K bound in the medium—fueling larger, denser flowers and improved flower quality. Ideal for use with hydroponic or soil-based systems, its pH-stable, low-EC formula works seamlessly with any feeding program. PK Synergy also supports trichome development and essential oil expression by improving nutrient flow to flower sites, making it a powerful bloom-stage microbial tool for growers who want to elevate both yield and aroma. Concentrated at 400 million CFU/mL, it's trusted by expert growers for consistent, high-quality harvests and is safe for use on all flowering plants, including fruits and edibles. Mixes easily with water and fits right into your bloom schedule.

• BIGGER YIELDS AND HEAVIER FLOWERS: This bloom yield enhancer helps maximize bloom potential by unlocking phosphorus and potassium at the root zone—driving larger, denser flowers during peak bloom
• PK BOOSTER MICROBES THAT UNLOCK NUTRIENTS: With P-K strains like Bacillus megaterium, Pseudomonas putida, Bacillus mucilaginosus, and Frateuria aurantia, this bloom nutrient enhancer frees up bound nutrients for rapid absorption
• INCREASES TRICHOMES AND RESIN PRODUCTION: Supports essential oil and trichome production by enhancing nutrient delivery to flower sites, resulting in sticky, aromatic, bloom-phase flowers
• LOW EC BLOOM ADDITIVE THAT’S PH STABLE: This low EC bloom additive is pH stable and fully compatible with hydroponics and soil, adding microbial benefits without disrupting your current nutrient program
• CONCENTRATED BLOOM MICROBES IN EVERY DOSE: Delivers 400 million CFU/mL of high CFU bloom microbes—making it a powerful microbial additive that performs reliably across the entire bloom cycle
• NATURAL BLOOM BOOSTER WITH MICROBIAL SUPPORT: Unlike salt-based additives, this natural bloom booster offers microbial bloom support through advanced plant nutrition without the risk of overfeeding
• GROWER-TESTED RESULTS, HARVEST AFTER HARVEST: This trusted bloom additive delivers grower-tested results—helping commercial and home growers alike achieve proven flower enhancer effects across cycles
• MIXES WITH WATER AND SAFE FOR ALL PLANTS: Mixes easily with water and works on all plant types, including edible plants. Can be used throughout bloom as part of any feeding program—indoor or outdoor
