Precision-formulated using British pharmaceutical-grade ingredients, this high-purity supplement delivers the essential primary nutrients required to fuel the high-energy demands of the bloom cycle. It ensures your plants have the mineral depth needed to produce dense, heavy clusters without the risk of impurities slowing down metabolic processes.\u003c\/p\u003e\n\n\u003cp\u003eWhile indispensable during peak flowering, ISN Potash is highly versatile and can be applied at half-strength during the vegetative stage to reinforce vascular strength and accelerate early root branching. Fully pH-buffered and designed to dissolve instantly, it ensures maximum nutrient stability and absorption without altering your reservoir's delicate balance. This makes it the definitive choice for high-performance hydroponic systems where precision and cleanliness are paramount for success.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cb\u003eBest For:\u003c\/b\u003e Stimulating abundant flower and bud development, increasing final fruit size and density, bolstering root development, and maintaining pH stability in automated hydroponic systems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003ePharmaceutical-Grade Purity:\u003c\/b\u003e Manufactured using top-tier British pharmaceutical-grade ingredients, ensuring an ultra-clean formula completely free from heavy metals or unwanted impurities.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003epH-Buffered Hydroponic Design:\u003c\/b\u003e Specifically engineered for hydroponic setups, featuring built-in pH buffers that keep your reservoir stable and minimise daily adjustments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eDual-Phase Versatility:\u003c\/b\u003e provides critical phosphorus and potassium for massive floral structures, while offering cell-strengthening benefits when used at half-strength during vegetative growth.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eHigh Solubility \u0026amp; Cleanliness:\u003c\/b\u003e Dissolves completely in water without leaving gritty residue, preventing clogged drip lines, misters, and feed pumps.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eVascular and Structural Support:\u003c\/b\u003e Strengthens internal plant tissue and water-transport pathways, helping heavy-yielding crops support their own weight without snapping.\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;\"\u003eISN Nutrients (International Superior 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;\"\u003ePotassium \u0026amp; Phosphorus (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\u003eIngredients\u003c\/b\u003e\u003c\/td\u003e\n    \u003ctd style=\"padding: 8px;\"\u003eBritish Pharmaceutical-Grade P and K\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;\"\u003eFlowering (Full Strength) \/ Vegetative (Half Strength)\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, 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;\"\u003e1 Litre, 5 Litre, and 20 Litre\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\u003eBloom Phase Accelerator:\u003c\/b\u003e Integrate into your feeding schedule from the onset of flower formation to maximise essential oil production and final crop yield.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eVegetative Frame Builder:\u003c\/b\u003e Apply at half-strength during the early growth cycle to encourage thicker stalks and a more robust root system.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCommercial Hydroponic Systems:\u003c\/b\u003e Run in large-scale reservoirs where pH stability and sediment-free delivery are critical to operational efficiency.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eUsage Tip:\u003c\/b\u003e For the best results, use ISN Potash in conjunction with ISN Seaweed.
