CANNA Substra Flores A (3-0-3) & B (1-3-5) Hard Water | Bloom Nutrient Kit

CANNA Substra Flores A&B Hard Water: Two-Part Bloom Nutrient for Inert Media

CANNA Substra Flores A&B Hard Water delivers a complete two-part flowering formula designed for inert media like rockwool and run-to-waste hydroponic systems. The balanced profile reduces nitrogen while elevating potassium and phosphorus to match bloom demands, and chelated trace elements ensure consistent, canopy-wide uptake.

Substra Flores A (3-0-3) and B (1-3-5) for Hard Water Precision Feeding

The hard water formulation counteracts elevated mineral content in source water to maintain stable pH and optimal nutrient availability through the flowering cycle. Part A (3-0-3) and Part B (1-3-5) together cover all macro and micronutrients for the bloom phase, supporting strong metabolism, prolific flower set, and efficient performance in rockwool and run-to-waste setups.

Key Features

• Hard Water Formula: buffered for high-mineral source water to maintain pH stability and consistent nutrient delivery through flowering
• Two-Part Bloom Nutrition: Part A (3-0-3) and Part B (1-3-5) together deliver a complete bloom-phase macro and micronutrient profile
• Chelated Trace Elements: readily bioavailable micronutrients maximize uptake uniformity across the full canopy
• Inert Media Optimization: developed specifically for rockwool and run-to-waste hydroponics with precise mineral ratios for the bloom phase
• Bloom-Phase NPK Shift: reduces nitrogen while elevating potassium and phosphorus to align with the plant's flowering demands
