Terra Aquatica Feed Chart – TriPart Doses and EC
Terra Aquatica's own published TriPart schedule for hydroponics and coco. Millilitres per litre of water, by growth stage.
- All dosesper LITRE
- pH5.5 – 6.5
- Base feed0.5–2ml of each part
- Chart runs bygrowth stage
Growing in soil or coco instead?
Terra Aquatica publish a different set of figures for each, and they are not interchangeable — the soil rates in particular run a long way below the ones above.
- Terra Aquatica soil feed chart — the same three TriPart bottles, at the lower rates Terra Aquatica publish for potting mixes.
- Terra Aquatica DualPart Coco feed chart — the two-part feed built for coco specifically, Coco Grow and Coco Bloom.
Getting it right
- Never premix the concentrates. Terra Aquatica are explicit: each part goes into the water separately, or they crystallise. Rinse the jug between parts.
- Match the Micro to your water. Over 70 mg/L calcium takes the hard water Micro; soft or RO water takes the soft water version.
- The chart is staged, not dated. Terra Aquatica index by what the plant is doing — first roots, first true leaves, growing, pre-flowering, flowering, ripening — so read the plant, not the calendar.
- Empty the reservoir every 10 to 14 days.
- FinalPart is used alone, for about ten days, after everything else stops — up to 5ml per litre in hydro and coco.
- Keep foliar sprays under EC 0.6 and off the plant during flowering.

Common questions
Is this the same as the old GHE Flora series?
Yes. General Hydroponics Europe became Terra Aquatica, and Flora Micro, Grow and Bloom became TriPart Micro, Grow and Bloom. The bottles and the ratios carried over.
Hard water or soft water Micro?
Terra Aquatica set the line at about 70 mg/L of calcium. Above that, hard water. On RO or rainwater, soft water — and add CalMag back.
Why are the doses per litre and not per 10 litres?
Because that is how Terra Aquatica publish them. Multiply by ten if you are working from a brand that uses 10-litre doses — mixing the two conventions up is the most common feeding mistake we see.
Do I need Fulvic, Seaweed and Pro Roots?
No — the three base parts do the work. Pro Roots early and Seaweed through the run are the two most growers keep.
