Canna Hydro Flores A & B — Professional Two-Part Flowering Nutrient for Run-to-Waste Systems
Best for: Experienced hydro growers running clay pebbles or rockwool who want precision nutrients built for the flowering stage
Our thoughts
Canna Hydro Flores is the real deal if you're serious about run-to-waste hydroponics. Dutch-engineered, pH-stable out of the bottle, and formulated specifically for the flowering cycle. It's not cheap, but you're paying for precision here — not marketing.
Canna Hydro Flores A & B is a two-part professional nutrient system engineered specifically for the flowering stage in run-to-waste hydroponic systems. Built on decades of Dutch research, it's a complete flowering feed with optimised NPK ratios, chelated trace elements, and built-in pH correction. This is proper kit for growers who know their systems and want nutrients that actually match their setup rather than a one-size-fits-all compromise.
How it compares
Canna Hydro Flores sits at the professional end of the two-part flowering nutrient market.
- More concentrated than some alternatives — precise dosing means you're not paying for water
- Hard water (HW) and soft water (SW) variants mean regional water chemistry is already dialled in
- Built-in pH stabilisers reduce fiddling and guesswork
- Specifically designed for run-to-waste, not recirculating systems — different formulation logic
- Comparable to General Hydroponics or Advanced Nutrients, but Dutch engineering with proven track record
Usage guidance
System requirements
Run-to-waste hydroponic systems only — clay pebbles, rockwool, or similar inert media. Not suitable for soil or coco substrates.
Mixing
Add Part A to your reservoir first, stir thoroughly, then add Part B. Let the mixture stand for a few hours before feeding. Never mix A and B together directly — you'll get insoluble compounds the plant can't use.
Dosage
Apply 2–4 ml per litre of each part (A and B). Use 2 ml/litre for light feeders, up to 4 ml/litre for heavy feeding plants. Target EC between 1.8–2.7 mS/cm. Drip feed 1–3 times daily with 10–20% drain-to-waste runoff.
pH management
Maintain solution pH between 5.2–6.2. Canna formulation includes pH correctors, but always check and adjust as needed for your water.
Flushing
Flush with water every 1–2 weeks to prevent salt buildup in intensive setups.

Who this is for
- Experienced hydroponic growers with run-to-waste system knowledge
- Growers using clay pebbles or rockwool specifically
- Those already comfortable with two-part nutrient mixing and EC/pH management
- Anyone in hard or soft water areas looking for region-optimised nutrients
- Semi-commercial or commercial operations where precision counts
Not a beginner product. This is for growers who understand their system and want professional-grade nutrients that actually match it.
Our take
Canna Hydro Flores does exactly what a flowering nutrient should — it's built for run-to-waste, pH-stable, and formulated with the NPK ratio flowering plants actually need. The hard water/soft water variants show proper attention to real-world growing conditions.
If you're running hydro seriously and want nutrients that fit your system rather than fighting against it, worth picking up. This is the kind of kit that pays for itself in better results.
