Terra Aquatica DualPart Coco Feed Chart – Doses
Terra Aquatica's own published DualPart Coco schedule — the two-part feed built for coco specifically. Millilitres per litre of water, by growth stage.
- All dosesper LITRE
- pH5.5 – 6.5
- Base feed0.5–3ml of each part
- RipeningFinalPart 5ml
Both bottles go in at every stage, in changing proportions — Terra Aquatica label them Coco Grow and Coco Bloom rather than A and B.
Getting it right
- Both parts, all the way through. This is not a grow-then-bloom switch: the ratio shifts, but neither bottle drops out until Flower 7.
- Never premix the concentrates. Each part goes into the water separately.
- Empty the reservoir every 10 to 14 days.
- Flower 7 and Flower 8 are FinalPart alone, at up to 5ml per litre — Terra Aquatica's ripening period, about ten days.
- DualPart Coco or TriPart in coco? Both work. DualPart is the simpler two-bottle route built for the medium; TriPart gives you finer control and covers hydro as well.

Common questions
Is DualPart Coco the same as Coco A and B?
It is the same idea — a two-part coco feed — but Terra Aquatica name the bottles Coco Grow and Coco Bloom, and the ratio between them changes through the run rather than staying equal.
Do I still need CalMag?
On RO or very soft water, yes. Coco holds and releases calcium in a way that catches people out, which is why the CalMag sits alongside almost every coco schedule.
Why are the doses per litre?
Because that is how Terra Aquatica publish them. Multiply by ten if you are used to a brand that doses per 10 litres.
