CANNA Substra Vega Hard Water A (4-0-3) & B (1-2-4). Veg Nutrient. 20 Liters

CANNA Substra Vega Hard Water A&B: Two-Part Veg Nutrient for Inert Media CANNA Substra Vega Hard Water A (4-0-3) & B (1-2-4) is a two-part mineral base nutrient formulated for the vegetative stage in hard-water growing regions. Designed for inert substrates such as rockwool and perlite in run-to-waste and drain-to-waste hydroponic systems, it delivers readily available nitrogen compounds and a balanced trace element profile for fast, uniform vegetative development. Hard-Water Optimized Formula for Rockwool, Perlite, and Drain-to-Waste Systems Substra Vega Hard Water runs clean with no residue, supporting stable EC and pH management throughout the vegetative phase. The hard-water formulation compensates for elevated calcium, magnesium, and carbonate levels common in municipal water sources, so plants receive a consistent, balanced feed regardless of local water quality. Use Part A and Part B together through the full vegetative cycle for consistent shoot growth, dense root development, and a well-structured canopy before transitioning to flowering. Key Features Hard-Water Optimized Formula: compensates for elevated Ca/Mg and carbonate levels in municipal water for consistent, balanced veg nutrition regardless of source water quality Inert Media Ready: formulated for rockwool, perlite, and other inert substrates in run-to-waste and drain-to-waste hydroponic systems Fast Vegetative Push: readily available nitrogen compounds and trace elements support vigorous shoot growth, root density, and uniform canopy development Clean-Running, Residue-Free: formula runs clear in rockwool and perlite systems, maintaining stable EC and pH without clogging lines or drippers Two-Part A&B System: separate A and B bottles ensure stability of reactive elements and allow precise, consistent nutrient delivery throughout the veg cycle Technical Specifications Specification Value Brand CANNA Product Substra Vega A & B, hard water version NPK Part A 4-0-3, Part B 1-2-4 Size 20 L set, one 20 L can each of A and B (SKU CASVHKIT3) Growth stage Vegetative Dosage 0.5 fl oz/gal (40 mL per 10 L) maximum, A and B in equal amounts Recommended EC 0.8 - 1.5 mS/cm (A + B, source water at 0.0 EC) Recommended pH 5.2 - 6.2 Water gift 3 - 5 L per m² per day Water type Hard tap water Growing media Inert substrates such as rockwool, run-to-waste Mixing Never mix A and B concentrates directly
