CANNA Substra Flores A (3-0-3) & B (1-3-5) Soft Water | Bloom Nutrient Kit – 20 Liter

CANNA Substra Flores A&B Soft Water: Bloom Nutrient for Low-Mineral Water Systems CANNA Substra Flores A&B Soft Water delivers a complete two-part flowering formula for inert media and run-to-waste hydroponics using soft or low-mineral source water. The profile reduces nitrogen while raising potassium and phosphorus to meet the plant's bloom needs, with chelated trace elements for consistent, canopy-wide uptake. Substra Flores A (3-0-3) and B (1-3-5) Calibrated for Soft Water Hydroponics The soft water formulation adjusts mineral ratios to account for low-calcium and low-magnesium source water, maintaining stable pH and optimal nutrient availability without the buffering load of a hard water formula. Part A (3-0-3) and Part B (1-3-5) together provide a complete feed that supports strong bloom metabolism, prolific flower set, and efficient system performance in rockwool and run-to-waste setups. Key Features Soft Water Calibration: formulated for low-mineral source water to maintain stable pH and nutrient availability across the bloom cycle Two-Part Bloom Nutrition: Part A (3-0-3) and Part B (1-3-5) deliver all macro and micronutrients needed for the full flowering phase Chelated Trace Elements: bioavailable micronutrients for uniform uptake and consistent development across the canopy Bloom-Phase NPK Profile: reduces nitrogen while raising K and P to align with the plant's specific flowering demands Inert Media Optimization: developed for rockwool and run-to-waste systems for reliable performance throughout the bloom window Technical Specifications Specification Value Brand CANNA Product Substra Flores A & B, soft water version NPK Part A 3-0-3, Part B 1-3-5 Size 20 L set, one 20 L can each of A and B (SKU CASFSKIT3) Growth stage Flowering Dosage 0.5 fl oz/gal (40 mL per 10 L) maximum, A and B in equal amounts Recommended EC 0.8 - 1.8 mS/cm (A + B, source water at 0.0 EC) Recommended pH 5.2 - 6.2 Water gift 4 - 6 L per m² per day Water type Soft or RO source water Growing media Inert substrates such as rockwool, run-to-waste Mixing Never mix A and B concentrates directly
