The culprit is the bicarbonate in British tap water, and it gets more stubborn just when flowering plants need things steady.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIONIC Hard Water Bloom\u003c\/strong\u003e is the flowering partner to Hard Water Grow, made specifically for hard or mains tap water. It's more acidic than the standard Hydro Bloom, so it neutralises those bicarbonates itself and you need less pH down. The calcium is balanced for what your tap water already brings, and the potassium to nitrogen ratio shifts towards flowers, fruit and yield. One bottle, nothing to mix.\u003c\/p\u003e\n\u003ch3\u003eWhy It Works\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigned for British hard water:\u003c\/strong\u003e formulated for the minerals already in your tap water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteadier pH:\u003c\/strong\u003e neutralises the bicarbonates that push hard water's pH up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for flowering:\u003c\/strong\u003e the K to N ratio is set for flowers, fruit and yield.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-part feed:\u003c\/strong\u003e no A and B to measure or mix in the right order.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLonger between tank changes:\u003c\/strong\u003e fewer hard-water problems means the reservoir stays balanced for longer.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFor Houseplant \u0026amp; Kitchen Growers\u003c\/h3\u003e\n\u003cp\u003eGrowing tomatoes, chillies or strawberries in a countertop hydro kit filled from a hard-water tap?
