Canna Aqua Feed Chart for Hydroponics: Doses and EC by Week
Greens Horticulture ·
The CANNA Aqua feed chart for recirculating hydroponic systems: Aqua Vega and Aqua Flores A and B doses week by week, the additives, and the EC to aim for. It is CANNA's own schedule, set out so it reads on a phone.
CANNA Aqua feeding schedule
CANNA gives every dose in ml per 10 litres of water, so divide by ten for ml per litre: 26-33 ml per 10 L is 2.6-3.3 ml per litre. EC is in mS/cm. EC water is what CANNA assumes your water starts at; EC total is the finished feed.

CANNA's Aqua chart assumes softer starting water (EC 0.2) than its Coco and Terra charts (EC 0.4).
Notes from CANNA
- * Double CANNAZYM to 50 ml per 10 L if you are reusing the substrate.
- ** CANNABOOST can go up to 40 ml per 10 L through flowering for extra strength.
- For a longer growth phase, repeat the rooting period II doses (days 6-25). For a longer flowering phase, repeat the generative phase I doses (weeks 3-5).
- PK 13/14 goes in for one week, 3-4 weeks before harvest.
- The schedule is written for plants that flower or fruit, starting from a cutting or seedling about a week old. How long each phase lasts depends on the plant.
Using Aqua in a recirculating system
- Aqua is made for systems where the feed runs back to the tank: NFT and flood and drain.
- Add A to the tank and stir or run the pump, then add B. Never mix A and B together neat.
- Top up and check EC and pH every day or two: plants drink water faster than food, so the tank drifts.
- Clay pebbles such as CANNA Aqua Clay Pebbles are the usual medium.
What you need
- CANNA Aqua Vega & Flores A+B - the base feeds.
- CANNA Rhizotonic, CANNAZYM, CANNABOOST and CANNA PK 13/14.
- pH and EC meters and, for hard water, water filtration.
