Applied during the critical mid-to-late bloom stage, this fast-acting formula delivers a powerful, targeted surge of Phosphorus (P) and Potassium (K) precisely when plants are ready to pack on maximum weight. It provides the essential mineral depth required to transform floral clusters into dense, heavy, and competition-grade harvests.\u003c\/p\u003e\n\n\u003cp\u003eBecause it is formulated as a highly refined powder, Extreme Boost provides maximum active concentration and outstanding cost-efficiency—delivering more high-impact applications per gram while being much easier to transport and store than bulky liquid options. It quickly dissolves in water, driving cell division, raising internal Brix (sugar) levels, and stimulating a massive increase in resin, terpene, and oil production. For growers seeking a sweeter, heavier finish with maximum trichome coverage, Extreme Boost is the definitive choice.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cb\u003eBest For:\u003c\/b\u003e Maximising final flower weight and density, accelerating late-stage ripening, boosting essential oil and resin output, elevating Brix levels, and providing a cost-efficient bloom-boosting solution.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eUltra-Concentrated Powder Formulation:\u003c\/b\u003e Offers exceptional active ingredient purity and cost-efficiency, giving commercial and hobby growers more feeding power per gram compared to traditional liquid PK boosters.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eExtreme Phosphorus \u0026amp; Potassium Levels:\u003c\/b\u003e Supplies a potent, fast-acting dose of bioavailable PK to fuel high-energy demands, forcing dense floral stacking and swelling.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBrix \u0026amp; Sugar Maximiser:\u003c\/b\u003e Actively raises internal plant sugar (Brix) levels, which directly translates to sweeter, higher-quality fruits and more robust flower structures.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eResin \u0026amp; Terpene Stimulator:\u003c\/b\u003e Triggers the plant's natural defence and oil-production mechanisms, coating flowers in a thick layer of sticky, highly aromatic trichomes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eClean, Clog-Free Hydroponic Design:\u003c\/b\u003e Refined, ultra-fine powder dissolves completely and instantly in water, leaving zero sediment to clog drip lines, active emitters, or hydroponic pumps.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; text-align: left;\"\u003e\n  \u003ctr style=\"border-bottom: 1px solid #ccc;\"\u003e\n    \u003cth style=\"padding: 8px;\"\u003eFeature\u003c\/th\u003e\n    \u003cth style=\"padding: 8px;\"\u003eDetails\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eBrand\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eProfessor's Nutrients\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eProduct Type\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eHigh-Performance Powdered PK Bloom Booster\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eApplication Phase\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eMid-to-Late Flowering \/ Ripening Stage\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eCompatible Media\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eHydroponics, Coco Coir, Rockwool, and Soil\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e\u003cb\u003eAvailable Sizes\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003e250g, 500g, 1kg, 2.5kg, and 5kg\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cb\u003eIdeal For:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eLate-Stage Floral Swelling:\u003c\/b\u003e Introduce to your feeding schedule during the heaviest weeks of flower development to encourage rapid cell division and maximum final weight.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eHigh-Yield Hydroponic Systems:\u003c\/b\u003e Perfect for clean recirculating or run-to-waste reservoirs where maintaining a sediment-free nutrient solution is essential.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eEssential Oil Extraction Prep:\u003c\/b\u003e Apply to high-value crops to maximise trichome density and terpene profiles, ensuring higher extraction yields and premium quality.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eUsage Tip:\u003c\/b\u003e Extreme Boost is extremely potent.
