Ionic Hydro Bloom (Hard Water)

Flowering nutrition for hard water

IONIC Hard Water Bloom is a one-part base nutrient designed for flowering plants grown with mineral-rich tap water. It helps manage the extra calcium found in hard water while supporting the nutrient balance required for flowering and fruit production.

Key benefits

• One-part flowering feed with no A and B mixing
• Designed specifically for hard or tap water
• Helps prevent excess calcium from disrupting nutrient uptake
• Supports potassium and magnesium availability
• Provides a controlled potassium-to-nitrogen balance for flowering

Application guide

Use 6ml per litre at the start of flowering, tapering to 5ml per litre through weeks 6–12. Add PK at 1ml per litre from week 8 where required, then follow the hard-water schedule for the final stage.

Important

Use this formula with hard or tap water. For soft or reverse-osmosis water, choose the standard Hydro Bloom feed instead.

Available sizes

Available in 1 litre, 5 litre and 20 litre bottles.
