Terra Aquatica TriPart FloraBloom - Flowering-Stage Base Nutrient
Best for: Growers running a three-part feeding programme who need the flowering-stage base nutrient to pair with FloraGro and FloraMicro.
Our thoughts
This is the flowering half of one of the longest-running base nutrient systems in hydroponics - Terra Aquatica is the European rebrand of General Hydroponics, and TriPart is essentially the same Flora Series formula growers have relied on for decades. If you want a base nutrient with a genuine track record rather than something new and unproven, this is a safe, well-understood choice.
TriPart FloraBloom is the flowering-stage component of Terra Aquatica's three-part base nutrient system, used alongside FloraGro (vegetative growth) and FloraMicro (micronutrients, used throughout) to build a complete base feed. As the name suggests, the three-part structure lets you adjust the ratio of each component through the grow cycle rather than relying on a single fixed-ratio bottle, shifting the balance from FloraGro-heavy in veg to FloraBloom-heavy through flowering to support the plant's changing nutrient demands.
How it compares
One of the most established base nutrient formulas on the market, sold under different names depending on region.
- Directly equivalent to General Hydroponics' FloraBloom, sold in the US and elsewhere under the original General Hydroponics branding - Terra Aquatica is that same company's European identity, not a separate competing formula.
- Compared to two-part systems like Canna Coco A+B, the three-part structure gives finer control over the grow-to-bloom ratio through the cycle, at the cost of an extra bottle to manage.
- Compared to premium three-part ranges like Advanced Nutrients' pH Perfect Grow/Micro/Bloom, TriPart sits at a lower price point without the built-in pH buffering, so you'll want to check and adjust pH manually.
A well-proven formula rather than a new or unusual one - the main trade-off against pricier three-part systems is manual pH management.
Usage guidance
Early flowering
Start increasing the FloraBloom ratio relative to FloraGro as plants move into pre-flower, following Terra Aquatica's published feed chart for your specific week of flower.
Peak flowering
Dosage typically increases through the flowering stages, commonly cited in the region of 0.5ml/L early on rising toward 2.4ml/L at peak flower - always confirm against the current Terra Aquatica feed chart for your grow type.
Mixing order
Add FloraMicro first, then FloraGro, then FloraBloom, stirring well between each addition to avoid nutrient components reacting directly with each other in concentrated form.
Reservoir use
Suitable for recirculating hydro systems as well as hand watering in coco or soil - adjust concentration to your growing medium and check EC/pH after mixing.

- Companion products: TriPart FloraGro, TriPart FloraMicro, Pro Roots
Who this is for
- Growers already running Terra Aquatica TriPart FloraGro who need the matching bloom-stage component
- Growers wanting finer control over their veg-to-bloom nutrient ratio than a single-bottle feed allows
- Anyone switching from General Hydroponics' US Flora Series and wanting the equivalent European product
- Larger grows where buying the 5L or 10L size brings the per-litre cost down significantly
Buy alongside FloraGro and FloraMicro if you're starting the system from scratch - buying FloraBloom on its own only makes sense if you're already running the other two.
Our take
TriPart FloraBloom is a known quantity - the same formula behind General Hydroponics' Flora Series, rebranded for the European market, with decades of real-world use behind it. Buy the size that matches your reservoir volume and growing scale to avoid paying for concentrate you won't use before it degrades.
One we sell a lot of for growers who want a base nutrient they can trust without having to guess. Proper kit at a price that makes sense.
