HydroTops Hydro Bloom (HW) — 2-Part Flowering Base

HydroTops Hydro Bloom (HW) — 2-Part Flowering Base for Hydroponic Systems

A complete 2-part base nutrient for flowering-phase hydroponic growing — organic and mineral components working together to deliver impressive harvests. Builds on the foundation laid by HydroTops Hydro Grow, shifting nutrient ratios toward flowering demand (less nitrogen, more phosphorus and potassium). HW variant for UK hard-water supplies.

Why growers choose HydroTops Hydro Bloom HW:

• 2-part A&B formulation — prevents nutrient lockout in concentrated form
• Hard-water (HW) variant — formulated for UK tap water mineral content
• Hydroponic-specific — for inert-media systems (DWC, NFT, clay pebbles, rockwool)
• Organic + mineral hybrid — broader biological support than pure mineral feeds
• Shifted for flowering demand — reduced N, increased P and K
• Builds on Hydro Grow foundation — continuity from veg to flower with matched formulations
• Drives impressive flowering harvests — measurable performance vs budget alternatives

Who it's not for:

Specifically for hydroponic (inert media) systems — for coco, use HydroTops Coco Bloom; for soil, use Solo Soil Bloom. Switch from Hydro Grow when flowering begins. HW for hard UK tap water — soft-water users should pick the SW formulation. For the complete HydroTops flowering stack, pair with Triple F, Floral Boost, and Flush.
