Canna Coco A&B — Two-Part Coco Nutrients Built for Real Growing
Best for: Coco growers who want a professional-grade nutrient system that actually understands how coco substrate works
Our thoughts
This is the nutrient system serious coco growers reach for. Canna spent 30 years researching how coco coir actually behaves, and it shows. One formula for both growth and flowering phases, properly balanced for how coco binds calcium and potassium. No messing about, no stage-switching headaches. You mix it right, you get results.
Canna Coco A&B is a two-part base nutrient system engineered specifically for coco coir cultivation. Unlike generic nutrient lines, this is formulated to address coco's unique chemistry — the way it exchanges cations, how it binds certain minerals, what it actually needs to deliver explosive growth and profuse flowering. One formula covers both growth and flowering phases, meaning you're not swapping bottles mid-cycle. It dissolves cleanly, works across all watering systems, and does exactly what a coco nutrient should do.
How it compares
Canna Coco sits in the professional-grade tier of two-part coco nutrients.
-
vs General Hydroponics FloraDuo: Similar two-part approach, but FloraDuo is a broader hydro system. Canna is coco-specific from the ground up.
-
vs Advanced Nutrients Sensi Coco: Advanced adds pH buffering tech, but Canna's formulation is built on 30+ years of direct coco research. Simpler, not gimmicked.
-
vs House & Garden Coco: Equivalent research pedigree and performance, premium pricing. Canna offers the same science at a slightly lower cost.
-
vs three-part systems: One formula instead of three means less complexity, fewer bottles, faster mixing. You sacrifice micro-adjustment for simplicity and reliability.
Usage guidance
Mixing & dosing
Add equal parts A and B to your water reservoir. Never mix the concentrates directly together — always dilute separately first. This stops the high calcium and phosphate levels from locking up. Use at a dilution ratio of 1:250 (40ml A + 40ml B per 10 litres of water).
EC & pH targets
Aim for an EC of 0.8–1.8 mS/cm and adjust to pH 5.5–6.2. Coco works in a tighter pH window than soil, so keep a pH pen handy.
Run-to-waste systems
This nutrient is built for managed runoff. The buffering action needs time to work, so it suits drain-to-waste growing where runoff is controlled by moisture content rather than constant overflow.
Hand watering & flood systems
Works cleanly in both. Dissolves directly, no sludge, no clogging in lines.
Water quality matters
Canna Coco A&B works best with decent water. If you're using RO or soft water, consider adding a separate calcium-magnesium supplement — coco binds these elements differently than soil, and you'll see deficiencies without it.

Who this is for
- Coco growers who want one formula that covers the whole cycle — no mid-stage nutrient changes
- Growers tired of generic hydro nutrients that don't account for coco's chemistry
- Anyone running drain-to-waste, flood, or ebb and flow systems on coco
- Serious growers willing to pay for research-backed formulation over budget alternatives
- Experienced nutrient users who understand pH and EC management
Not a beginner plug-and-play system — you need to understand mixing order, pH ranges, and why calmag matters on coco. That said, once you know the basics, this is the system you'll come back to.
Our take
Canna Coco A&B is the nutrient system growers actually use when they're serious about results. Thirty years of research into how coco substrate behaves, tested on real plants, refined by professional growers worldwide. The chemistry is solid, the formulation is coco-specific, and the one-formula approach saves you headaches mid-cycle.
Yes, it costs more than generic two-parts. You're paying for research, consistency, and a nutrient system built for your medium, not against it. Good time to buy while stock lasts.
