Canna Aqua Flores A & B — Two-Part Flowering Nutrients for Recirculating Hydroponics
Best for: Growers running NFT or flood & drain systems who want professional-grade flowering nutrients with zero pH headaches
Our thoughts
If you're serious about recirculating hydroponics, Canna Aqua Flores does what the pros use. The self-regulating pH system alone saves you hours of fiddling, and the formulation is built specifically for flowering, not as a compromise between veg and bloom. It's the nutrient most UK growers with established systems reach for — for good reason.
Canna Aqua Flores is a professional two-part base nutrient engineered specifically for the flowering stage in recirculating hydroponic systems. Unlike full-cycle nutrients that try to handle veg and bloom equally, this is formulated where it matters: lower nitrogen, elevated phosphorus and potassium, plus added silicon and chelated trace elements. The real game-changer is the built-in pH stabilisation system — set your starting pH once, and it stays in range without constant adjustment.
How it compares
This sits in the professional tier of two-part hydroponic base nutrients.
- Self-regulating pH formula — competitors require manual adjustment throughout the cycle
- Stage-specific formulation (flowering only) — more precise than full-cycle alternatives
- Silicon included — saves buying a separate additive
- UK market standard — most established growers use Canna Aqua in recirculating systems
- Designed for moderate to hard water (typical UK tapwater) — may need adjustment in soft water areas
Usage guidance
Canna Aqua Flores is designed for recirculating systems only — NFT channels, flood & drain tables, and aeroponics with inert media like rockwool, hydroton, or perlite.
Mixing (critical)
Always add Part A first, stir well, then add Part B. Never mix the concentrate bottles together — this creates insoluble bonds the plant cannot absorb. Use equal volumes of A and B.
Dosing
Use 2–4ml per litre of water (equivalent to 20–40ml per 10L). Start at 2ml/L for light-feeding plants, 4ml/L for heavy feeders. This gives an EC range of 1.3–2.1 mS/cm depending on your tapwater hardness.
Timing
Begin from the moment flower formation starts. Fill your reservoir, add diluted nutrients, set pH to 5.2–6.2, and leave it. The buffer system keeps it stable — you shouldn't need to adjust again.
Maintenance
Refresh your reservoir every seven days. Let tapwater sit 24 hours before adding nutrients to allow chlorine to evaporate.
Technical specifications

- Stage: Flowering phase only
- System compatibility: Recirculating hydroponics (NFT, flood & drain, aeroponics)
- Media compatibility: Inert only (rockwool, hydroton, perlite)
- Dosage: 2–4ml per litre (20–40ml per 10L)
- EC range: 1.3–2.1 mS/cm
- Target pH: 5.2–6.2 (self-regulating)
- Key additives: Silicon, fulvic acid, humic acid, chelated trace elements, pH stabilisers
- Available sizes: 1L, 5L, 10L bottles
- Water suitability: Moderate to hard tapwater (UK standard). Not recommended for soft water areas without adjustment
Who this is for
- Growers running established NFT or flood & drain systems
- Those who want to eliminate pH adjustment during flowering
- Experienced hydroponic growers who value precision and reliability
- Anyone in moderate-to-hard water areas (most of UK)
- Growers wanting a professional nutrient without guesswork
Not suited to passive systems like deep water culture or buckets — this is built for active recirculation.
Our take
Canna Aqua Flores does exactly what professional growers need from a flowering nutrient. The self-regulating pH system alone justifies the price — it removes the daily pH chasing that sinks most systems. Combined with the stage-specific formulation and built-in silicon, this is proper kit that performs consistently across hundreds of UK growing rooms.
If you're serious about recirculating hydroponics and tired of nutrient complexity, this is worth picking up. Good time to buy while stock lasts.
