TriPart Micro Hard Water 5 Liters Terra Aquatica is the micronutrient base of the TriPart program for water with more than 70 mg/L of calcium. It provides nitrogen, potassium, and chelated elements throughout the entire indoor cultivation.

TriPart Micro Hard Water 5 Liters Terra Aquatica, previously known as FloraMicro Hard Water, is a concentrated mineral fertilizer developed to complete the TriPart nutritional program in areas where the water contains a high amount of calcium.
The formula provides nitrogen, potassium, microelements, and submicroelements that participate in growth, photosynthesis, enzymatic activity, and the formation of new tissues.
It should be used together with TriPart Grow and TriPart Bloom, adjusting the proportions of the three components according to the stage of cultivation.
The 5-liter format is suitable for indoor installations with irrigation tanks, hydroponic systems, coco fiber, or numerous plants grown in soil.
The hard water version avoids adding an unnecessary amount of calcium when the starting water already contains this mineral in a high concentration.
TriPart Micro Hard Water 5 Liters Terra Aquatica is the central component of the TriPart fertilization system. The range consists of TriPart Grow, TriPart Micro, and TriPart Bloom. Each part provides a different combination of nutrients and allows you to modify the mix during growth, pre-flowering, and flowering.
Micro provides a stable base of nitrogen, potassium, and micronutrients. The hard water formulation incorporates less calcium than the soft water variant, since the water used already provides a considerable amount of this element.
Terra Aquatica recommends choosing this version when a water analysis indicates a calcium concentration higher than 70 mg per liter. Electrical conductivity alone does not allow you to accurately know the amount of calcium, so it is advisable to consult the analysis provided by the water supply company.
The product can be used in soil, coco fiber, hydroponics, and aeroponics. The high solubility facilitates the preparation of tanks and use in automated irrigation systems, as long as the components are properly diluted.
TriPart Micro Hard Water is used to provide the essential microelements that plants need in small amounts. These include iron, manganese, zinc, copper, boron, and molybdenum. These minerals are involved in photosynthesis, chlorophyll production, nitrogen transformation, and numerous enzymatic reactions.
The formula also provides nitrogen, an element related to the formation of leaves, stems, proteins, and vegetative tissues. Potassium participates in the transport of water and sugars, the regulation of stomata, and different metabolic processes.
In indoor cultivation, balanced nutrition is especially important because intense lighting can accelerate growth and increase the demand for minerals. A lack of micronutrients can cause chlorosis, deformities, lower photosynthetic activity, or slow growth.
The hard water version helps avoid an excess of calcium within the solution. Using a soft water formula with highly mineralized water could unnecessarily raise the calcium concentration and make it difficult to balance other elements.
Before using TriPart Micro Hard Water 5 Liters Terra Aquatica, the container must be shaken well. Each TriPart fertilizer should be added to the water separately, mixing carefully after each addition.
TriPart Grow, Micro, and Bloom should not be mixed in concentrated form. Direct contact between the products can generate precipitates and reduce the availability of some minerals.
In hydroponics and coco fiber, the Terra Aquatica guideline table establishes the following amounts for TriPart Micro:
In soil cultivation, the recommended amounts are lower:
These amounts should be combined with the corresponding doses of TriPart Grow and TriPart Bloom. After adding the three fertilizers, electrical conductivity and pH should be measured and adjusted.
The doses are indicative and can be modified according to the variety, plant size, light intensity, temperature, and initial EC of the water. For young plants, it is advisable to start with a moderate concentration and increase it progressively.
In hydroponic systems, the tank level, water temperature, pH, and EC must be checked regularly. In soil or coco, the irrigation frequency should be adapted to drainage, pot size, and drying rate.
The composition of TriPart Micro Hard Water 5 Liters Terra Aquatica includes primary, secondary nutrients, and a wide set of trace elements. The commercial formula has an approximate NPK ratio 5-0-1.
The microelements appear in carefully selected forms and several of them are chelated to improve stability and availability within the nutrient solution.
The percentages may appear expressed differently depending on the labeling and market regulations. The label on the purchased container should be used as a reference to consult the exact legal composition.
TriPart Micro Hard Water 5 Liters Terra Aquatica is a liquid mineral fertilizer developed for water with a high calcium concentration. It is part of the Terra Aquatica TriPart program, previously known as Flora Series.
It should not be considered only a growth stimulator. Micro works as an essential part of complete nutrition and is used from the first roots to flowering, varying the amounts together with Grow and Bloom.
The TriPart system is based on a
