CANNA Classic Flores is a complete two-part nutrient for the flowering phase, developed specifically for inert run-to-waste systems. It accounts for the shift in nutrient demand that happens at the flip — less nitrogen, more potassium and phosphorus — and delivers chelated trace elements in directly absorbable form to support exuberant bloom. Like Classic Vega, it is built for systems where drainage water is discarded rather than recirculated, giving plants a fresh, precisely calibrated nutrient solution on every feed. Available in 1L, 5L, 10L, and 20L sets.
Specifications
- Always add Classic Flores A to your reservoir first, stir well, then add B — mixing A and B concentrates directly forms insoluble compounds the plant cannot absorb.
- Flores runs at a slightly higher EC than Vega at the same dilution rate — expect 1.8–2.7 mS/cm rather than the 1.5–2.4 you were running in veg.
- Shake the bottle well before each use — chelated trace elements can settle during storage.
- Store in a cool, dark, frost-free location away from UV light, which degrades the iron chelate in the formula.
How to Use

Complete the Classic programme with Boost, Cannazym, PK 13/14, and the full CANNA additive range.
SubstratesInert run-to-waste substrates — coco RTW, rockwool, perlite, and clay pebbles that Classic Flores is designed to feed.
Meters & PensMeasure EC and pH on every feed — flowering plants are consuming harder and salt management matters more than at any other stage.
Frequently Asked Questions
What is the difference between Classic Flores and Aqua Flores?
Classic Flores is for inert run-to-waste systems where drainage water is discarded. Aqua Flores is engineered for recirculating hydroponic systems where the same solution passes through the root zone repeatedly. Using the wrong formula for your system affects pH stability and nutrient delivery.
Why does Flores have a higher EC than Vega at the same dilution?
Flores contains a higher concentration of phosphorus and potassium — the nutrients plants demand most during flowering. This higher mineral load results in an EC of 1.8–2.7 mS/cm at the standard 1:250 dilution, compared to 1.5–2.4 mS/cm for Classic Vega.
When should I switch from Classic Vega to Classic Flores?
At the flip to 12/12 (or at the start of the flowering period for autoflowers). CANNA recommends a clean switch to Flores at this point — the plant's nutrient demands shift significantly at the onset of flowering and Flores is formulated to match those demands immediately.
Can I add CANNA Boost and PK 13/14 alongside Classic Flores?
Yes. Flores is designed to work within the full CANNA programme. Boost from week 1 of flower and PK 13/14 during peak flowering weeks are a well-established combination with Classic Flores A&B — check the CANNA feed chart for recommended stacking doses.
Which size should I buy?
The 1L set suits small grows or first-time CANNA users. The 5L is most practical for 2–6 plant grows through a full flowering cycle. The 10L and 20L suit larger operations or growers running back-to-back cycles where buying in bulk reduces cost per litre significantly.
