CANNA Classic Vega is a complete two-part nutrient for the vegetative phase, developed specifically for inert run-to-waste systems. In these setups — whether rockwool, coco RTW, perlite, or similar inert substrates — drainage water is not returned to the reservoir, so plants receive a fresh nutrient solution on every feed. Classic Vega is formulated to take full advantage of this precision, delivering directly absorbable nitrogen compounds, high-quality EDDHA iron chelate, and trace elements from the very first feed. Available in 1L, 5L, 10L, and 20L sets.
Specifications
- Always add Classic Vega A to your reservoir first, stir well, then add B — never combine A and B concentrates directly as insoluble compounds will form that the plant cannot absorb.
- Shake the bottle well before use — EDDHA iron chelate can settle during storage and needs to be redistributed before dosing.
- Store in a cool, dark, frost-free location — UV light degrades the iron chelates in the nutrient solution over time.
- Flush with plain water every 1–2 weeks when feeding intensively to prevent salt accumulation in the substrate.

Frequently Asked Questions
What is a run-to-waste system?
A run-to-waste system is one where drainage water is discarded rather than recirculated back to the reservoir. This means plants receive a completely fresh nutrient solution on every feed, minimising the risk of salt accumulation and pathogen build-up in the reservoir. CANNA Classic is designed specifically for this growing method.
Can I use Classic Vega in a recirculating system?
No — Classic Vega is formulated for run-to-waste systems. For recirculating hydroponic setups, CANNA Aqua Vega is the correct product. Using a run-to-waste formula in a recirculating system causes pH instability and uneven nutrient availability over time.
Why should I never mix A and B concentrates directly?
Mixing A and B concentrates without water causes calcium to react with phosphates and sulphates, forming insoluble precipitates the plant cannot absorb. Always add A to your reservoir water first, stir, then add B — the water acts as a buffer that prevents the reaction.
What EC should I target with Classic Vega?
At the standard 1:250 dilution (400ml A + 400ml B per 100L), the solution EC from Classic Vega sits at 1.5–2.4 mS/cm. This figure includes the contribution of your water's own EC — so softer water will sit toward the lower end, harder water toward the upper end of this range.
Which size should I buy?
The 1L set suits small grows and first-time CANNA users. The 5L covers most 2–6 plant grows through a full veg cycle. The 10L and 20L are for larger operations or growers running CANNA Classic consistently across multiple cycles where bulk pricing makes a meaningful difference per litre.
