CANNA Coco A&B is the industry-standard two-part base nutrient designed specifically for coco growers, and works best twinned with Canna Coco Natural or Canna Coco Professional Plus. It’s an easy-to-use formula that covers both the vegetative and bloom stages, so you only need one feed throughout your entire grow. Whether you’re hand-watering or running a drain-to-waste system, Coco A&B delivers consistently strong results. Why Choose CANNA Coco A&B? All-in-one feed: One formula for both veg and bloom — no need to swap bottles between stages. Works in buffered coco: Perfect for use with CANNA Coco Professional Plus or other pre-buffered coir substrates. Agnostic water profile: Formulated to perform consistently regardless of local water hardness. Balanced nutrition: Provides the ideal mix of nitrogen, calcium, magnesium, potassium and trace elements tailored to coco coir’s cation exchange profile. How to Use Mixing Instructions: Shake bottles well before use. Fill your reservoir or container with water. Add Coco A at around 40 ml per 10 L of water (≈ 4 ml/L), stir thoroughly. Add Coco B at the same rate, stir again and let it settle. Never mix A & B concentrates directly together — always dilute separately into water. Adjust to a target pH of 5.5–6.2. EC Feed Range According to CANNA’s official grow schedule, the recommended EC ranges (including source water) are: Propagation: 0.8–1.2 mS/cm Vegetative growth: 1.2–1.8 mS/cm Blooming: 1.6–2.0 mS/cm Always check runoff and adjust your dosage to match plant needs.

CANNA PK 13/14 — bloom booster to stack on extra weight mid-flower. Suitability CANNA Coco A&B is made for coco coir substrates in both hand-watered pots and automated drain-to-waste irrigation. Check out Canna Coco Natural or Canna Coco Professional Plus. It’s not designed for recirculating hydro systems — for those, look at CANNA Aqua or Hydro. In coco, A&B provides everything the plant needs without extra supplements. Quick Tips Always measure A and B separately — never pour concentrates into the same measuring jug. Flush through with plain water occasionally if salts build up. Store bottles in a cool, dark place — nutrients are light and temperature sensitive. FAQs Is CANNA Coco A&B for veg or bloom?Both — it’s a single base feed that works across the full lifecycle. Can I use it in run-to-waste systems?Yes. Coco A&B is ideal for drain-to-waste setups in buffered coco. How much do I use per litre?Start around 4 ml/L of both A and B. Adjust by measuring EC and observing plant response. What additives should I use with it?Rhizotonic, Cannazym, and PK 13/14 are the classic trio for pushing plants to their full potential.
