Canna Aqua Flores A&B — Two-Part Hydroponic Nutrients for Flowering Recirculating Systems
Best for: Growers running NFT, flood & drain, or other recirculating hydroponic systems who want reliable flowering nutrients without constant pH fiddling
Our thoughts
Canna Aqua Flores is what happens when a Dutch nutrient company gets recirculating hydroponics properly sorted. The pH stabilisation alone saves you hours of messing about, and the two-part setup gives you control without the complexity of three-part systems. One we see recommended constantly by UK growers running serious hydroponic setups.
Canna Aqua Flores A&B is a two-part base nutrient system purpose-built for the flowering stage in recirculating hydroponic systems like NFT and flood & drain. Made by CANNA — a Dutch horticulture company that's become the go-to nutrient brand for UK hydroponics — it delivers the potassium and phosphorus your plants need during bloom whilst keeping your nutrient solution stable without constant pH adjustment. Unlike cheaper one-part feeds or complicated three-part systems, Aqua Flores hits a sweet spot: proper nutrient control with built-in pH stabilisers, silicon, humic acids, and fulvic acids already factored in. No guessing, no supplementary additives needed.
How it compares
Aqua Flores sits in the professional mid-range of hydroponic base nutrients.
-
vs. one-part nutrients: More control over bloom ratios, but less fiddling than three-part systems
-
vs. General Hydroponics Flora (3-part): Simpler to mix and manage; built-in pH stability saves daily adjustments
-
vs. Advanced Nutrients (3-part): More straightforward, less premium pricing, same professional results in recirculating systems
-
vs. budget hydro feeds: You're getting chelated trace elements, silicon, and pH buffering as standard — stuff budget brands charge extra for or leave out entirely
The key difference: Aqua Flores is designed specifically for recirculating closed-loop systems, not run-to-waste. That specificity matters. Your pH stays stable. You don't waste time chasing numbers.
Usage guidance
Canna Aqua Flores is straightforward once you understand the mixing protocol.
When to switch
Move from CANNA Aqua Vega A&B (vegetative) to Aqua Flores the moment your plants start showing flower formation. The nutrient profile shifts from nitrogen-heavy to potassium and phosphorus-dominant — exactly what plants need during bloom.
Mixing (this matters)
Always add equal parts A and B to your water separately, then stir well before applying. Never mix Part A and Part B together neat — they'll react and lock up essential elements. Always water first, nutrients second.
Dosage
Use 2–4ml per litre of both A and B, depending on plant demand:
- 2ml/litre for light-feeding plants
- 3ml/litre for moderate feeders (safe starting point)
- 4ml/litre for heavy-feeding varieties in peak bloom
Alternatively, 30ml A + 30ml B per 10 litres of tap water.
Recirculating systems (NFT, flood & drain, DWC)
Run your feed at EC 1.3–2.1 mS/cm and pH 5.2–5.8. Because of the pH stabilisers in Aqua Flores, you should hit your target pH and stay there. Most growers report needing zero pH adjustment after initial setup — a genuine time-saver in commercial or multi-tank setups.
Water hardness note (UK growers)
Canna Aqua Flores is formulated for mid-range Dutch water hardness and performs perfectly in moderately hard English water. If you're running soft water, you may encounter issues — CANNA's soft-water Hydro range is better suited to those areas.

Who this is for
- Intermediate to advanced hydroponic growers running recirculating systems
- Anyone who's tired of constant pH adjustment with simpler feeds
- Commercial or multi-tank operations where reliability and consistency matter
- Growers in moderate-to-hard water areas across the UK
- Serious hobbyists who want professional-grade nutrients without premium brand markup
- Operators running clay pebbles, rockwool, or other inert media in closed-loop systems
Aqua Flores is particularly well suited to growers who've outgrown simple one-part feeds but don't want the complexity of managing three separate bottles every feed cycle.
Our take
Canna Aqua Flores is a genuinely clever product. It solves the actual problems growers face in recirculating systems — pH creep, nutrient complexity, missing additives — and does it without pretension or unnecessary upsell. The pH stabilisation alone justifies the investment if you're running multiple tanks or a commercial setup.
If you're setting up or upgrading a recirculating hydroponic system and want base nutrients that won't add hours of daily maintenance, this is worth picking up. Proven performance, trusted across UK professional hydroponics, and it does exactly what it should, day in, day out.
