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
