Canna Substra Vega A

CANNA Substra Vega A is a complete professional two-part nutrient designed for the vegetative growth phase of plants. Formulated specifically for inert run-to-waste systems, it delivers the macro and micronutrients a plant needs during the early stage when it is establishing side shoots and building the root and canopy structure that determines its final yield potential.

Canna Substra Vega A Specifications

CANNA Substra Vega A is Part A of a two-part nutrient set (used alongside Substra Vega B). It is intended exclusively for the vegetative growth stage and is engineered for inert substrates used in run-to-waste hydroponic systems.

Why Choose Canna Substra Vega A

CANNA Substra Vega A is purpose-built for growers running inert run-to-waste systems who want a clean, professional nutrient program for the vegetative stage. Here is what distinguishes it from a general-purpose nutrient:

• Formulated for run-to-waste systems: Unlike recirculating nutrient formulas, Substra Vega is engineered for single-pass delivery through inert media. The nutrient ratios account for the fact that solution is not recaptured and adjusted, making it easier to dial in a consistent feed program.
• Supports side shoot development: The vegetative-stage formula prioritizes the nutrients that drive branching and canopy expansion. A well-developed vegetative stage translates directly into greater flower or fruit sites later in the cycle.
• Complete professional nutrient: Substra Vega A (combined with Part B) delivers a full spectrum of macro and micronutrients required during the veg phase, reducing the need for supplemental additives during this stage.
• Two-part system for precision: Separating the nutrient into A and B parts prevents premature precipitation of certain mineral salts. Each part is stable in concentrate form, and they combine correctly when added individually to the reservoir or feed water.
• CANNA’s professional grower pedigree: CANNA has a long track record as a nutrient manufacturer for commercial and dedicated hobby growers. The Substra line is part of their core substrate-specific product range rather than an entry-level offering.

Best Uses for Canna Substra Vega A

CANNA Substra Vega A is the right choice when the following conditions describe your grow setup:

• Inert run-to-waste hydroponic setups: This is the primary design target. If your system drains nutrient solution to waste rather than recirculating it, Substra Vega is formulated for that pattern of nutrient delivery.
• Rockwool, clay pebbles, or similar inert media: The nutrient ratios are calibrated for substrates that contribute nothing nutritionally to the plant, meaning the grower controls 100% of nutrient input through the solution.
• Vegetative growth stage only: Substra Vega is a veg-phase product. Switch to CANNA Substra Flores A & B when transitioning to the flowering or fruiting stage.
• Growers who pair nutrients with grow lighting upgrades: If you are running high-output lighting such as an Eye Hortilux 600W ceramic HPS bulb or a high-output T5 like the Sun Blaze T5 HO 8-lamp fixture, a matched professional nutrient program ensures the plant can actually use the extra photosynthetic capacity.
• Commercial-scale or dedicated hobby grows: Substra Vega is a professional product. Growers who want a no-compromise base nutrient for a structured veg-to-flower cycle will get more value from it than from general-purpose options.

Dosing Guidelines

CANNA Substra Vega A is used as a two-part base nutrient alongside Substra Vega B. General guidance for inert run-to-waste systems:

• Add Part A and Part B separately to your feed water — never mix the concentrates directly together before diluting.
• Add Part A to water first, stir or circulate, then add Part B. This prevents localized precipitation.
• Target a pH of 5.8–6.2 in the final nutrient solution for inert substrate applications.
• Monitor electrical conductivity (EC) of both the feed solution and the runoff to track uptake and adjust dosing as the plant grows.
• During early vegetative growth, plants typically require a lower EC than at peak vegetative stage — start conservatively and increase as the canopy fills out.
• Consult the CANNA feed schedule for Substra Vega, available at canna.com, for specific ml/L or ml/gallon rates by week.
