Terra Aquatica FloraBloom 0.5l
Terra Aquatica FloraBloom 0.5 litre is the bloom component of the TriPart three-part nutrient system, originally co-developed with NASA scientists and the University of California Davis. FloraBloom delivers the phosphorus, potassium and magnesium required for vigorous root formation during vegetative growth and maximum flower and fruit production during the bloom phase. With an NPK ratio of 0-5-4 supplemented by 3% magnesium oxide, 5% sulphur trioxide and silicic acid for active protection against fungal pathogens and root rot. Use alongside TriPart Grow and TriPart Micro with ratio adjustments per growth stage. The 0.5 litre bottle is the ideal trial format for evaluating the TriPart system.
Terra Aquatica FloraBloom 0.5L – Bloom nutrient from the TriPart three-part system
Flower and fruit quality are the ultimate metrics of any grow — and that is precisely what FloraBloom is engineered to optimise. As the bloom component of the iconic Terra Aquatica TriPart system, this formulation delivers the phosphorus and potassium plants require to express their full genetic potential during flowering and fruiting. The TriPart concept has been the global benchmark since 1976, adopted by hobbyists, commercial growers and research laboratories worldwide. The 0.5 litre bottle provides an accessible entry point for growers evaluating this proven three-part platform.
Formulation breakdown
FloraBloom features an NPK of 0-5-4 supplemented with 3% magnesium oxide and 5% sulphur trioxide. The zero-nitrogen profile combined with elevated phosphorus and potassium concentrations directs nutrition toward flower initiation, fruit development and ripening. Magnesium maintains photosynthetic efficiency even when the plant channels maximum energy into reproductive organs. Integrated silicic acid provides supplementary defence against fungal pathogens.
- Phosphorus (P₂O₅) 5%: drives flower initiation and energy transfer to reproductive sites.
- Potassium (K₂O) 4%: regulates water balance and strengthens cell walls during fruit swell.
- Magnesium (MgO) 3%: central chlorophyll component, maintains active photosynthesis.
- Silicic acid: preventive action against fungal infection and root rot.
Progressive dosage within the TriPart schedule
FloraBloom is used throughout the entire cycle at progressive dosages: low during veg (0.5 ml/L in hydro), ramping up to 2.4 ml/L at peak bloom. In soil, from 0.2 ml/L to 2.1 ml/L. Always combine with FloraGro and FloraMicro. Add each component separately to the reservoir to prevent flocculation.
Why the 0.5 litre format?
The 0.5L bottle is the optimal trial size for growers assessing the TriPart system. Paired with 0.5L bottles of FloraGro and FloraMicro, it forms a complete starter kit covering multiple grow cycles. Also practical as a top-up when one component depletes faster than the others.

How many ml of FloraBloom per litre of water should I use?
Dosage progresses with the growth stage. In hydroponics, start at 0.5 ml/L during early roots and increase to 2.4 ml/L at peak bloom. In soil, from 0.2 to 2.1 ml/L. The official TriPart feed chart provides exact weekly ratios for all three components.
Does FloraBloom contain nitrogen?
No, FloraBloom has an NPK of 0-5-4 — it contains zero nitrogen. Nitrogen supply comes from FloraGro and FloraMicro. By reducing FloraGro and increasing FloraBloom during the transition to flowering, nitrogen naturally decreases in favour of phosphorus and potassium.
What is the difference between FloraBloom and a standalone PK booster?
FloraBloom is not a standalone PK booster but an integral component of the three-part TriPart system. It contains phosphorus, potassium, magnesium, sulphur and silicic acid. By combining the three TriPart components, no separate PK, CalMag or grow nutrients are required.
Is FloraBloom 0.5L compatible with both hard and soft water?
FloraBloom is universal and works with any water type. Only the FloraMicro component differs depending on water hardness: use Hard Water for tap water above 70 mg/L calcium, Soft Water for soft or reverse osmosis water. FloraBloom and FloraGro remain identical.
