Terra Aquatica FloraMicro Hard Water 1l
Terra Aquatica FloraMicro Hard Water 1 litre is the micronutrient foundation of the TriPart three-part nutrient system — the Hard Water variant formulated for tap water exceeding 70 mg/L calcium, which applies to large parts of Flanders and Wallonia. With an NPK of 5-0-1 and an adjusted calcium dosage calibrated to your water source, plus dual-chelated iron and the complete spectrum of EDTA-chelated trace elements, FloraMicro forms the stable base upon which FloraGro and FloraBloom build. Integrated pH stabilisers maintain consistent solution chemistry. Essential from first roots through harvest. Compatible with hydroponics, coco and soil. The 1 litre bottle is the standard format for regular growers.
Terra Aquatica FloraMicro Hard Water 1L – The TriPart base calibrated for hard water regions
In many Belgian municipalities, tap water is naturally rich in calcium and minerals. This is not a disadvantage per se, but your nutrient program must be calibrated accordingly. Terra Aquatica FloraMicro Hard Water 1L is precisely engineered for this: the foundation of the modular TriPart system, calibrated for water exceeding 70 mg/L calcium. The 1 litre bottle is the reference format for growers who run the Terra Aquatica system as their standard base.
Why the Hard Water variant matters
The Hard Water formulation contains less calcium than the Soft Water version, as your tap water already supplies this element. This prevents excess that can cause:
- Calcium accumulation: blocks drip systems and inhibits magnesium and iron uptake.
- pH instability: excess calcium drives pH upward, disrupting nutrient balance.
- Reduced performance: blocked trace element uptake limits overall plant potential.
The remaining micronutrient profile is identical to the Soft Water variant: NPK 5-0-1, iron (0.12% EDDHA/PDTA), boron, manganese, zinc, copper and molybdenum — all chelated for maximum stability.
From growth to bloom: always add first
FloraMicro is used throughout the entire cycle at a relatively constant dosage. In hydroponics: 0.5 to 2.0 ml/L. Always add first to the water, before FloraGro and FloraBloom. It is FloraGro and FloraBloom whose ratios shift per growth phase — FloraMicro remains the constant factor.
The 1 litre format: the logical choice
The 1L bottle delivers the optimal cost-to-volume ratio for regular growers. Pair it with 1L FloraGro and FloraBloom, or choose a TriPack Hard Water bundling all three components in one box.

What is the difference between FloraMicro Hard Water and Soft Water?
The Hard Water variant contains less calcium as your tap water already supplies it. The Soft Water variant contains more calcium to compensate for the deficit in soft and RO water. All other micronutrients are identical. Choose Hard Water above 70 mg/L calcium.
Is Belgian tap water generally hard or soft?
This varies significantly by region. Most of Flanders and Wallonia has hard to very hard water (well above 70 mg/L calcium). Brussels and some Ardennes municipalities have softer water. Check with your local water supplier for the correct choice.
Do I need a CalMag supplement with FloraMicro Hard Water?
With hard tap water, a separate CalMag supplement is virtually never necessary. Your water already supplies calcium, and FloraMicro provides the remaining micro-elements and complementary macronutrients. The three-part TriPart system is designed as a self-sufficient concept.
Does the dosage of FloraGro and FloraBloom change with Hard Water?
No, FloraGro and FloraBloom are universal — their dosage is identical regardless of whether you use FloraMicro Hard Water or Soft Water. Only the FloraMicro component differs. The feed chart for the three components combined remains the same.
