The summary
- What's inside: four one-litre bottles — TriPart Grow, TriPart Micro, TriPart Bloom, and the liquid pH- corrector.
- Which version: soft water below 70 mg of calcium per litre, hard water above. Only the Micro bottle differs.
- What it covers: approximately 555 L of solution at full growth rate, considerably more at gentler stages. One season across several tanks.
- How much to use: 1.8 ml of Grow, 1.2 of Micro, and 0.6 of Bloom per litre during growth. The calculator converts for your reservoir.
- Safety note: Micro is classified H318 and pH- is corrosive H314. Gloves and eye protection when measuring doses.
- Dispatch: approximately 4.8 kg, shipped together in a single parcel from France.
The three TriPart fertilisers and the pH corrector, one litre each
The complete TriPart pack from Terra Aquatica brings together four 1 L bottles, Grow, Micro, Bloom and the pH- corrector, for complete hydroponic nutrition. At the full growth dose, it makes up about 555 L of solution. The Micro is available in a soft water version, below 70 mg of calcium per litre, or a hard water version.
This pack brings together the four one-litre bottles that make up a complete hydroponic nutrient programme: the three parts of the TriPart system, Grow, Micro and Bloom, plus the pH- corrector that keeps the solution in the range where it all remains absorbable. A direct successor to the Flora Series, it is made in Fleurance, in the Gers.
🔢 The order of addition
You fill the reservoir, add each part separately, rinsing the measuring cup between each, mix, and then adjust the pH last with the pH-. The order matters for a precise chemical reason: the calcium in the Micro and the phosphorus in the Bloom, when brought into contact in concentrated form, form an insoluble phosphate that drops to the bottom of the container and can no longer be absorbed. Diluted in the reservoir water, they coexist without any problem. The corrector goes in last because each of the three fertilisers changes the value as it dissolves.
Micro first
It is poured into the reservoir water, with the doser rinsed immediately afterwards. This is the one that carries the calcium.
The Grow, then the Bloom
Each is poured separately, with mixing in between. A concentrate must never be poured directly into another.
pH last
Every fertiliser shifts the pH as it dissolves. Correcting beforehand means correcting twice.
Choosing the Micro version based on your calcium level
Only one bottle differs between the two versions, the Micro: calcium nitrate at 15 to 22.5% for soft water, 5 to 10% for hard water. The benchmark is 70 mg of calcium per litre: below that, choose the soft water version; above it, the hard water version. The total hardness drop test gives you the answer in German degrees, and since 1 °dGH corresponds to 7.1 mg of calcium per litre, water that stays below 10 °dGH suits the soft water version.
The dosage and the two hazard statements
Never pour one concentrate into another, and do not dose with the cap: a volume estimated by eye shifts the concentration of the solution, and the error accumulates with each top-up. The Micro is classified H318, causing serious eye damage, and the pH- is classified H314, corrosive, at pH 1: put on your gloves and goggles when dosing, and rinse for a long time in the event of a splash. The Grow and the Bloom are not classified as hazardous. Once everything is diluted to the working doses, these risks no longer exist.
🧫 The volume of solution covered
The calculation is straightforward: 1,000 ml divided by the dose in millilitres per litre. At the full-growth dose, one litre of Grow gives you 555 litres of solution, one litre of Micro 833 litres and one litre of Bloom 1,666 litres. In pre-flowering, Grow and Micro go up to 2 ml per litre and each covers 500 litres. In flowering, the roles reverse: Bloom goes up to 2.4 ml per litre, so its container covers 416 litres and runs out first.
🪴 The bottle you'll go through first
If you prepare the same volume of solution at each of the five stages, Micro runs out first, though only just, because the sum of its doses across the five stages is the highest of the three: its litre then covers about 158 litres per stage, or nearly 790 litres over the cycle. A 30-litre reservoir renewed every 2 weeks uses 390 litres in 6 months, and the pack comfortably covers that season. In soil, the application chart provides lower doses, for example 1.5 ml of Grow per litre in the growth stage instead of 1.8, which stretches the pack even further. The indoor hydroponics guide helps you size a first reservoir.
🎯 pH and conductivity
The target pH is 5.5 to 6.5 during rooting and growth, then 6.4 to 6.8 in pre-flowering and flowering. For the first addition of pH-down, allow 4 ml per 50 litres of solution, then top up in small doses, measuring as you go. Conductivity is measured afterwards, once the pH has been adjusted: in hydroponics and on coco fibre, it goes from 0.3 to 0.6 mS at the first roots to 1.3 to 1.8 mS in growth, then to 1.8 to 2.0 mS in pre-flowering and 1.4 to 2.2 mS in flowering. If your reading is clearly outside these guidelines, adjust the dose of the three fertilisers rather than that of the corrector.

To budget for separately
- pH measurement
- Drop test kit or pH meterWithout a measurement, the pH- bottle is dosed blind. The drop test requires no calibration and is perfectly adequate to start with.
- Graduated measure
- Syringe or measuring cylinderDoses range from 0.5 to 2.4 ml per litre, that is 10 to 48 ml for a 20-litre reservoir.
- Conductivity meter
- A probe meterIt shows that a reservoir is concentrating through evaporation, or that a solution has become too dilute, before the plant shows any signs.
- Rinsing container
- A dedicated glass of clean waterPlaced beside the reservoir, it lets you rinse the dispenser between uses without going back to the sink.

What each of the four bottles in the pack does
Three fertilisers and a pH corrector. This table explains what each one provides, when it is dominant, and which ones require gloves.
The fourth bottle is not a fertiliser
The pH corrector is added last, and its dose does not appear in any table: it depends on your water. The other three are dosed per litre.

Full doses for hydroponics and coco fibre, in millilitres per litre, in the order Grow, Micro, Bloom: first roots 0.5 / 0.5 / 0.5; first true leaves 1 / 1 / 1; growth 1.8 / 1.2 / 0.6; pre-flowering 2 / 2 / 1.5; flowering 0.8 / 1.6 / 2.4. In soil, use the dedicated column of the table: 0.2 ml per litre of each part at the first-roots stage, then 1.5 / 1 / 0.5 in growth and 0.7 / 1.4 / 2.1 in flowering. The pH- is added last, with no fixed dose: it depends on the buffering capacity of your water.
