Terra Aquatica FloraMicro Hard Water 5L – Professional-grade foundation for hard water growers
For professional growers operating with hard tap water, both the formulation and the format are critical cost factors. The 5 litre jerry can of FloraMicro Hard Water from Terra Aquatica delivers the lowest cost-per-litre in the range and sustained supply calibrated for calcium-rich water sources that characterise large parts of Belgium and Northern Europe.
Optimised for mineral-rich tap water
Hard tap water brings a substantial dose of calcium and minerals. The Hard Water formulation of FloraMicro is calibrated accordingly: less calcium than the Soft Water variant, preventing surplus that blocks uptake of other elements. The micronutrient package is otherwise identical:
- Nitrogen (N) 5%: balanced mix of nitrate (3.5%) and ammonium (1.5%).
- Iron (Fe) 0.12%: dual-chelated EDDHA + PDTA for extended pH availability.
- Complete trace elements: boron, manganese, zinc, copper and molybdenum — fully EDTA-chelated.
- pH stabilisers: maintain consistent solution chemistry during extended reservoir use.
Yield and supply planning at scale
At an average dosage of 1.5 ml/L, 5 litres of FloraMicro produces over 3,300 litres of nutrient solution. The consistent dosage profile makes consumption highly predictable — a significant logistical advantage for commercial operations. Always add FloraMicro first to the water, followed by FloraGro and FloraBloom.
The investment that pays for itself
The 5L jerry can delivers a substantially lower cost-per-litre compared to smaller formats. Pair with 5L FloraGro and FloraBloom for a complete professional inventory. For growers in hard water regions — which covers the majority of Belgium — this is the most practical and economical choice.

How many litres of nutrient solution does FloraMicro Hard Water 5L produce?
At an average dosage of 1.5 ml per litre, 5 litres of FloraMicro produces over 3,300 litres of nutrient solution. The consistent and predictable consumption rate makes supply planning straightforward for professional operations.
My tap water is hard — do I still need a CalMag supplement?
No, with hard tap water a separate CalMag is virtually never necessary. Your water already contains sufficient calcium, and FloraMicro Hard Water is precisely calibrated for this. The three-part TriPart system covers the full nutritional spectrum without additional supplements.
Can I combine FloraMicro Hard Water with RO water?
If you grow exclusively with RO water, the Soft Water variant is more appropriate as RO water contains virtually no calcium. If you blend RO water with hard tap water, the choice depends on the final calcium level of the mixture — measure it and decide based on the 70 mg/L threshold.
Is the 5 litre format more cost-effective?
Yes, the 5L jerry can offers a substantially lower cost-per-litre compared to the smaller formats. Given that FloraMicro is used at a constant dosage throughout the year, the 5L format represents the most economical option for regular and professional growers.
