This pack brings together the three parts of the TriPart system — Grow, Micro and Bloom — in one-litre bottles, along with the pH- adjuster that keeps the solution within the optimal uptake range. It prepares approximately 555 litres of solution at the full growth rate dose, in either soft water or hard water format.

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
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- adjuster that keeps the solution within the range where all of it remains absorbable. A direct successor to the Flora Series, it is manufactured in Fleurance, in the Gers.
🔢 The order of addition
Fill the reservoir, then pour in each part separately, rinsing the measuring jug between each one, mix thoroughly, and finally adjust the pH with the pH- corrector. 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, produce an insoluble phosphate that sinks to the bottom of the container and can no longer be absorbed. Once diluted in the reservoir water, they coexist without issue. The corrector goes in last because each of the three fertilisers alters 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, and 5 to 10% for hard water. The reference point is 70 mg of calcium per litre: below that, use the soft water version; above it, use the hard water version. The drop-based total hardness 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 is suited to the soft water version.
The dosage and the two hazard statements
Never pour one concentrate into another, and never measure by the cap: a volume estimated by eye shifts the concentration of the solution, and the error compounds with every top-up. Micro is classified H318, it causes serious eye damage, and pH- is classified H314, corrosive at pH 1: wear gloves and eye protection when measuring, and rinse thoroughly if splashed. Grow and Bloom carry no hazard classification. Once everything is diluted to working doses, these risks no longer apply.
🧫 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 gives 833 litres, and one litre of Bloom gives 1,666 litres. During pre-flowering, Grow and Micro move to 2 ml per litre and each cover 500 litres. In flowering, the roles reverse: Bloom moves to 2.4 ml per litre, meaning one bottle covers 416 litres and is the first to run out.
🪴 The bottle you'll go through first
If you prepare the same volume of solution at each of the five stages, it is the Micro that runs out first, just, because the sum of its doses across the five stages is the highest of the three: one litre covers approximately 158 litres per stage, or nearly 790 litres over the full cycle. A 30-litre reservoir refreshed every 2 weeks uses 390 litres over 6 months, and the pack comfortably covers that season. In soil, the application chart specifies lower doses, for example 1.5 ml of Grow per litre during growth rather than 1.8, which extends the pack's lifespan further. Our indoor hydroponics guide will help you size a first reservoir.
🎯 pH and conductivity
The target pH runs from 5.5 to 6.5 during rooting and growth, then from 6.4 to 6.8 at pre-flowering and flowering. For the first addition of pH-, allow 4 ml per 50 litres of solution, then top up in small increments whilst measuring. Conductivity is measured afterwards, once pH has been adjusted: in hydroponics and on coco fibre, it rises from 0.3 to 0.6 mS at first root development to 1.3 to 1.8 mS during growth, then 1.8 to 2.0 mS at pre-flowering and 1.4 to 2.2 mS at flowering. If your reading deviates significantly from these benchmarks, adjust the dose of the three fertilisers rather than the dose 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.
